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

Potential for Coal-to-Liquids Conversion in the United States—Fischer–Tropsch Synthesis

The United States has the world s largest coal reserves and Montana the highest potential for mega-mine development. Consequently, a large-scale effort to convert coal to liquids (CTL) has been proposed to create a major source of domestic transportation fuels from coal, and some prominent Montanans want to be at the center of that effort. We calculate that the energy efficiency of the best exi...

Technology Development for Iron and Cobalt Fischer-Tropsch Catalysts

A cobalt catalyst (25%Co/γ-Al2O3, prepared by slurry phase impregnation) was used in a fixed bed reactor under a pressure/density tuned supercritical fluid mixture of n-pentane/nhexane. By using an inert gas as a balancing gas to maintain a constant pressure, the density of the supercritical fluid could be tuned near the supercritical point while maintaining constant space velocity within the r...

REACTORS, KINETICS, AND CATALYSIS Diagnostic NonlinearAnalysisof Fischer-Tropsch Synthesis in Stirred-Tank Slurry Reactors

Multiplicity of steady states was experimentally obser®ed, somewhat sporadically, for ( ) Fischer Tropsch FT synthesis in stirred tank slurry reactors in the reactor originally ( ) at the wax-producing normal steady state suddenly jumping to a high-temperature ( ) methane-producing steady state for some time and e®entually returning to the normal steady state. A diagnostic nonlinear analysis sh...

Development of an Integrated Structure of CHP and Heavy Hydrocarbons Liquids Using Fischer-Tropsch Synthesis

Recent developments in gas-to-liquid conversion industry lead to reduction in initial investment, and it is expected by growth in demand for refined products in countries and the need to import these products in the countries. Implementing such projects can prevent currency outflow. In this article an integrated structure is developed for producing liquid fuels from natural gas through Fischer-...
