Stray politicians wandering in the political arena without party may put ''white collar'' people alongside businessmen, farmers, and wage-workers in their broadside appeals, but no platform of either major party has yet referred to them directly.
contact usmethanol was being manufactured from hydrocarbon feedstock (natural gas and coal) through a gasification process at production levels small compared to diesel or gasoline, the process was well established and could be scaled. Any feedstock that could be gasified into synthesis gas could potentially be used in the manufacture of methanol.
contact us· For the novel process, only 17.3% of the coal carbon is removed from the clean syngas and 77.6% of the coal carbon is fed into the methanol synthesis for methanol production. Finally, 73.8% of the coal carbon is converted into methanol and the purge gas with 3.7% of the coal carbon is combusted with coke-oven gas for heating the chemical ...
contact usCalcium looping is a promising technology to capture CO2 from the process of coal-fired power generation and gasification of coal/biomass for hydrogen production.
contact usCement production also is a key source of CO2 emissions, due in part to the significant reliance on coal and petroleum coke to fuel the kilns for clinker production. Globally, CO2 emissions from cement production were estimated at 829 MMTCO2 in 2000 7, approximately 3.4% of global CO 2 emissions from fossil fuel combustion and cement production.

contact usSince the mid- to late 1990s, the number and size of coal mines known as mountaintop removal mines increased dramatically in parts of ia, West ia, Pennsylvania, and Kentucky. The final step in processing this coal creates sludge that contains coal dust, sediment, and possibly heavy metals and chemicals. Mine operators contain the coal sludge in nearby valleys, behind huge earthen ...
