ABSTRACT:

A project to convert various cellulosic materials to quality liquid hydrocarbon transportation fuels is described. The major accomplishment was achieving projected liquid hydrocarbon yields of 30 to 40 gals/ton of cellulosic feedstock (dry, ash free) for synthesis gas compositions corresponding to that obtainable for average feedstocks and using relatively inexpensive cobalt/alumina type impregnated catalysts. The utility of using dolomite to adjust the H sub 2 /CO pyrolysis gas ratio was demonstrated. An iron liquefaction catalyst study was completed that confirmed the detriment of olefins in the feedgas for these type of catalysts (as opposed to cobalt based catalysts. Two completely new fluidized bed reactor systems were designed and installed to accommodate the liquefaction catalyst development work. An extensive simulator study on gasification transfer loop systems resulted in recommendations for system improvements. Modifications of the 6'' fluidized bed liquefaction reactor were also started based on simulator work.(ERA citation 08:029301)
