Title: Overview of Persulfate Activators for Textile Wastewater Treatment
Abstract: Recently, sulfate radical based advanced oxidation technologies has shown promising potential for decontamination purposes because of their high reactivity and great oxidative power. Of particular, activated persulfate (PS) processes have gained considerable interest in the treatment of textile wastewater. This presentation outlines ways employed for PS activation, which can be classified as energy, metal-based catalysts, carbon-based materials, base, and natural minerals. In energy-based activation, heat, ultrasound, microwave, and ultraviolet light are commonly used as energy sources to generate the formation of two SO4•– radicals by imparting energy to cause cleavages of the peroxide bonds in PDS anions. In a base-activated PS systems, alkaline addition (pH > 10) can activate persulfate to generate HO, SO4•–, and O2 radicals. Carbon-based and transition metals are the material frequently used in the materials-based activation. In the carbon-oxygen double bonds of activated carbon (AC) structure, the π electrons are highly susceptible to e- transfer. AC or biochar acts as an e--transfer mediator in PS activation to generate organic radicals and SO4•– on or near the surface of AC. Soil organic matter and glucose can also be used to activate persulfate. Low valency transition metals, such as Ag+, Co2+, Cu2+, Fe2+, and Mn2+, can also be used to activate PS by donating one electron through the radiolysis of water. Iron is the most favorable activator among the transition metals due to its non-toxic nature and low cost. However, the selection of a suitable Fe activator is critical. This presentation also reviews the prospect of using Fe-based materials, such as Fe2+ ion, nano-Fe0, Fe0 aggregates, magnetite, magnetic Fe-nanocomposites, and natural Fe2+-containing minerals (biotite, tourmaline, and iron sulfide), as persulfate activators in the PS process for the treatment of textile wastewaters containing azo dyes.

Title: Modeling for Some Meso-scale Phenomena in Pulverized Coal Combustion and Fast Fluidization
Abstract: It is very often for people to face various complex multi-phase reacting flow problems in simulation of large power generation systems and development of new energy conversion processes. The scales of the related phenomena can be different with each other for several orders of magnitude. Compared with the macroscopic and microscopic phenomena, the meso-scale ones are often less investigated and more difficult to model. However, they are often the crucial steps for complete modeling of these cross-scale engineering problems. Modeling of two different types of meso-scale phenomena will be presented and discussed.

The first one is a classical issue for pulverized coal combustion, i.e. whether the primary product of surface oxidation, CO, burns further in the boundary layer of the particle, i.e. a static meso-scale phenomenon. And how this boundary layer phenomenon is influenced by the turbulent flow in the furnace? i.e. a dynamic meso-scale problem. The moving flame front model developed for modeling the stagnant boundary layer reactions, and the binary Mont-Carlo approach for modeling the interactions between the stagnant boundary layer and the turbulent eddies will be reported for this subject.

The second subject is related with development of the chemical looping combustion and the dual fluidized bed gasifier, with which the fast fluidization provides the possibility of great solids flux exchange between different reactors. A newly developed type-A-choking-oriented unified model for fast fluidization dynamics will be reported, in which the meso-scale interactions between the continuous upward dilute flow and the discrete downward dense clusters will be introduced.

Title: Treatment of industrial wastewaters by fluidized-bed Fenton technology
Abstract: In the degradation of toxic wastewater, advanced oxidation processes (AOPs) are favored for high efficiency, low cost and being eco-friendly, using the generated non-selective hydroxyl radical (•OH) for oxidation. Among the AOPs, the Fenton process has been proven to be effective in the treatment of recalcitrant organic compounds. One disadvantage, however, is the production of a large amount of sludge that needs further treatment and disposal. The production of sludge is reduced by the use of fluidized-bed Fenton (FBF) process where iron is crystallized onto the surface of the carriers in the reactor. This presentation gives an overview of the recent developments on the application of FBF process to the treatment of industrial wastewater from thin film transistor liquid crystal display manufacturing, the production of pharmaceuticals, textiles, phenol, phenol derivatives, refractory organics, petrochemicals and other chemicals which shows the potential applicability of FBF technology to reduce the levels of recalcitrant organic contaminants in wastewater. The advantages of FBF process over other technologies that are based on Fenton oxidation in terms of performance, operating conditions and factors affecting the removal efficiency are highlighted. Included also are the reaction kinetics and mechanisms involved and the carriers that were used. Finally, large-scale applications are presented and described.

Title: Hydrogen the Fuel for 21st Century
Abstract: Non-Conventional Energy Sources, such as solar and hydrogen energy will remain available for infinite period. One of the reasons of great worry for all of us is reducing sources of conventional energy. We are consuming more energy than can be produced by nature. The results will be elimination of all the conventional sources of energy from the world most probably in this century itself. The other aspect is pollution added by these sources in our environment. The more we use these sources the poorer is our quality of life on this planet.
 
One of the frequently discussed candidates is hydrogen which when burnt in air produces a clean form of energy. In the last one decade hydrogen has attracted worldwide interest as a secondary energy carrier. This has generated comprehensive investigations on the technology involved and how to solve the problems of production, storage and applications of hydrogen. The interest in hydrogen as energy of the future is due to it being a clean energy, most abundant element in the universe, the lightest fuel, richest in energy per unit mass, produced easily using any source of energy and unlike electricity, it can be easily stored. Hydrogen gas is now considered to be the most promising fuel of the future.  It will provide, Cheap Electricity, Cook Food, Drive Car, Run Factories, Jet Planes, Hydrogen Village and for all our domestic energy requirements.
 
Hydrogen Energy Systems is making inroads in several directions. All the major car companies are manufacturing hydrogen fuel automobiles. Some cities have started demonstration projects using Hydrogen fuel transit buses. Long lasting, light and clean metal hydride batteries are already commercial for laptop computers. Larger capacity batteries are being developed for electrical cars. Hydrogen is already being used as the fuel of choice for space programmes around the world. It will be used to power aerospace transports to build the international space station, as well as to provide electricity and portable water for its inhabitants.
 
In short hydrogen shows the solution and also allows the progressive and non-traumatic transition of today’s energy sources, towards feasible safe reliable and complete sustainable energy chains. The present article deals with the storage, application and characterization aspect of hydrogen in the present energy scenario.
 
There are sufficient environmental and public health benefits of direct hydrogen fuel to justify moving ahead based on what we know already about fossil fuels, their consequences and their limitations. The coming decade will definitely see greater and greater use of “Green Power” so as to ensure less dependence on ‘Fossil Fuels’ and also in order to prevent environmental degradation.

Title: Generalized Building Energy Efficiency and New Energy Utilization
Abstract: The development of human society is a non-stop gear, and the way we use energy is about the future. How to use resources reasonably and effectively is the pressure we face. The increase in population is the problem of resource allocation—insufficient inventory of traditional energy sources. Economic development is a double-sided blade, and ecological environmental protection is our focus. Research and development of new energy and renewable energy is a way to block dependence on traditional energy sources.  The broad definition of building energy conservation is proposed, and the significance of using new energy to building energy conservation is expanded from the perspective of macro environment, including the use of integrated energy, solar energy, and energy islands to achieve zero energy consumption in building energy conservation. The construction has effectively promoted the development of zero energy consumption in terms of the life cycle and environmental protection.
