The significance of coal in the world economy remains unquestionable for decades. It is also expected to be the dominant fossil fuel in the foreseeable future. The increased awareness of sustainable development reflected in the relevant regulations implies, however, the need for the development and implementation of clean coal technologies on the one hand, and adequate analytical tools on the o...

Fischer-Tropsch synthesis is a part of Gas-to Liquids (GTL), Biomass-to-Liquids (BTL) and Coal to Liquids (CTL) technologies, which produce alternatives clean fuels from natural gas, biomass and coal. The catalytic performance of cobalt catalysts in Fischer-Tropsch synthesis strongly depends on the size of cobalt particles in nanoscale range (6-30 nm). Cobalt catalysts are usually prepared via ...

Executive Summary Western Research Institute (WRI) and its cosponsor Novinda Corporation (the Company was originally known as Amended Silicates, Inc.) proposed the development, characterization and testing of sorbents based on clay deposits abundant in Wyoming for the in-flight capture of mercury in pulverized coal derived flue gasses. As a part of the State of Wyoming’s Clean Coal Technologies...

The Clean Coal Technology (CCT) Demonstration Program is a government and industry co-funded effort to demonstrate a new generation of innovative coal utilization processes in a series of " showcase " facilities built across the country. These projects are carried out on a sufficiently large scale to prove commercial worthiness and generate data for design, construction, operation, and technica...

Carbon dioxide (CO2) emitted from conventional coal-based power plants is a growing concern for the environment. Chemical looping combustion (CLC), pre-combustion and oxy-fuel combustion are promising CO2 capture technologies which allow clean electricity generation from coal in an integrated gasification combined cycle (IGCC) power plant. This work compares the characteristics of the above thr...

Abstract This paper analyzed the current situation and development trends of energy consumption carbon emissions, trend coal in China. In context recently established peak neutralization targets, this put forward main problems associated with green low-carbon utilization coal. Five key technological innovation directions mining were proposed, including development, intelligent efficient mining,...
