Coal gasification plants lauded for clean power production.(COAL IN THE SPOTLIGHT)Mayer, Tony
Under the effects of environmental pollution, macro-economical conditions, markets downturn, and squeeze of clean energy, the operation condition of China's whole coal industry attracts more attentions in recent years. This study aims to investigate the comprehensive competitiveness of coal industry in ...
Pressurized coal gasification is not only the key part of the Integrated Gasification Combined Cycle (IGCC) but also the better approach to increase the gasification reaction rate and capacity of the unit gasifier. In this work, the gasification characteristics for a sub-bituminous coal with an air...
Worldwide, natural gas is the fuel typically used while in India 82% of DRI is produced in coal-based rotary kilns with the remainder being produced via gas-based routes (natural gas, syngas from coal gasification, coke oven gas, and gas using the Corex process). From there, the DRI, ...
The cement industry, an industry characterised by low margins, is responsible for approximately 7% of anthropogenic CO2 equivalent (CO2e) emissions and holds the highest carbon intensity of any industry per unit of revenue. To encourage complete decarbon
Underground coal gasification is a candidate process for converting the world's coal resources into energy, liquid fuels, and chemicals. In this article, a one-dimensional model of a reacting coal block called COALGAS is used to investigate the effects of operating conditions and coal properties ...
The "El Tremedal" Underground Coal Gasification (UCG) trial sponsored by Belgian, Spanish and United Kingdom government organisations and the European Community has conducted two gasification phases during the summer-autumn of 1997, of nine and five days duration respectively. A gas of good quality...
Several traditional reducing agents, such as pulverized coal, coke, diesel and natural gas, can be used to reduce magnetic iron in copper slag in an electric furnace with the blowing and stirring method. The main elements of waste cooking oil are C, H, and O; thus, the chemical composition...
Syngas can be obtained from different carbonaceous resources through the gasification of natural gas, coal, or biomass. Hence, this process presents a suitable alternative in order to produce base chemicals from resources other than crude oil. However, the lowest production costs of syngas and the ...
In co-gasification, the effect of parameters becomes very important when dealing with the co-gasification of different mixed materials. The objective of this review to study the effect of temperature, blending ratio, and equivalence ratio (ER) on catalytic co-gasification of biomass-coal, biomass-...
