K-PROMOTED MO/CO- AND MO/NI-CATALYZED FISCHER-TROPSCH SYNTHESIS OF AROMATIC HYDROCARBONS WITH AND WITHOUT A CU WATER GAS SHIFT CATALYST

摘要

With increasing population, economic development and limitednsupplies of fossil fuels, new approaches are needed to makenrenewable liquid fuels.1 The catalytic conversion of biomass-derivednsynthesis gas (CO + H2) to liquid hydrocarbons is an approach thatnhas been intensely studied for several decades. 2, 3 The major focus inngas-to-liquids (GTL) technology has been Fischer Tropsch (FT)nsynthesis 4, which converts synthesis gas into liquid hydrocarbonnfuels (Equation 1). Traditionally commercial catalysts used cobalt,niron and ruthenium 4, 5 though a variety of catalysts can be used.4nMolybdenum, on a zeolite (ZSM-5) support, has shown promise fornthe conversion of synthesis gas to liquid hydrocarbons 6 as havencobalt and nickel.2 However these systems can produce a wide rangenof hydrocarbons (C1-C60) during the reaction.6
