Research Trends in Fischer-Tropsch Catalysis for Coal to Liquids Technology

1 IntroductionCoal oil and coal gas were important fuel sources for heating and lighting in the last two centuries.Coal became less important with the start of the oil era and the widespread availability of natural gas.One of the major incentives for this transition was the decrease of the pollution by coal combustion.Coal remains one of the cheapest fossil resources and it is abundantly available in many places in t...  (本文共10页) 阅读全文>>

Fischer–Tropsch synthesis over iron catalysts with corncob-derived promoters

1.IntroductionWith the rapid development of economy,the demands of liq-uid hydrocarbons increasingly enlarge.Generally,Fischer–Tropschsynthesis(FTS)is considered as a promising route for the pro-duction of liquid hydrocarbons and other chemical raw materialsfrom syngas derived from coal,natural gas and biomass[1–5].Al-though cobalt and iron-based catalysts are common FTS catalysts,iron-based catalysts can be used und...  (本文共7页) 阅读全文>>

Fuzzy model prediction of Co(Ⅲ)/Al_2O_3 catalytic behavior in Fischer-Tropsch synthesis

1.Introduction Fischer-Tropsch synthesis(FTS)is an interesting and promising pathway for the conversion of synthesis gas to transportation fuels.FTS has been recognized as an important alternate technology to petroleum refining in the production of liquid fuels and chemicals from syngas derived from coal, natural gas and other carbon-containing materials[1?3].Sev- eral metals(including Fe,Co,Ni and Ru)are considered ...  (本文共8页) 阅读全文>>
