Thermochemical conversion of biomass offers an efficient and economically process to provide gaseous, liquid and solid fuels and prepare chemicals derived from biomass. Computational fluid dynamic (CFD) modeling applications on biomass thermochemical processes help to optimize the design and operation of thermochemical reactors. Recent progression in numerical techniques and computing efficacy ...

In the current world, increasingly developed industries of mankind have caused huge pollution to earth on which we live. And water resources, are source human life, also being seriously polluted and destroyed. Water has become an urgent need deal with in today’s world. order achieve sustainable development, people constantly using new materials process treatment. Biochar material is one them. t...

Fixed nitrogen is an essential chemical building block for plant and animal protein, which makes ammonia (NH3) a central component of synthetic fertilizer for the global production of food and biofuels. A global project on artificial photosynthesis may foster the development of production technologies for renewable NH3 fertilizer, hydrogen carrier and combustion fuel. This article presents an a...

A one-step, gas-phase photothermocatalytic process for the synthesis of hydrocarbons, including liquid alkanes, aromatics, and oxygenates, with carbon numbers (Cn) up to C13, from CO2 and water is demonstrated in a flow photoreactor operating at elevated temperatures (180-200 °C) and pressures (1-6 bar) using a 5% cobalt on TiO2 catalyst and under UV irradiation. A parametric study of temperatu...

Solar thermochemical hydrogen (STCH) generation is a promising approach for eco-friendly H2 production, but conventional STCH redox compounds cannot easily achieve desirable thermodynamic and kinetic properties phase stability simultaneously due to rather limited compositional space. Expanding from the nascent high-entropy ceramics field, this study explores new class of compositionally complex...

n this special issue, three papers belong to the path 1 , six papers o the path 2 , and two papers to the path 3 . The thermal path to generate electricity is referred as “concenrated solar power” or CSP. The greatly insolated “sunbelt” reions of the world include large Asian regions in China and India s well as the southwestern United States, southern Europe, Ausralia, the MENA regions, etc. T...
