ABSTRACT:

Some ZSM-5 supported ruthenium catalysts, prepared from Ru sub 3 (CO) sub12 and the acid form of ZSM-5 have been evaluated for their ability to catalyze synthesis gas conversion. The effect of weight percentage ruthenium loading and temperature of evaluation have been studied. Liquid hydrocarbons with varying percentages of aromatics, olefins and saturates are produced. This study on the three Ru/ZSM-5 catalyst indicated that the desired product can be obtained in relatively high yields when the Ru loading and temperature are selected. The product distribution for the 7.32% and 2.88% Ru/ZSM-5 catalysts are similar; however, the products obtained from the 0.98% catalyst were different from the other two catalysts. The aromatic content for the 0.98% catalyst was consistently higher than the 2.88% and 7.32% samples. Therefore, if a gasoline high in aromatics is desired the 0.98% Ru/ZSM-5 catalyst would warrant further study. The temperature affected the yield of the oil. The peak oil production occurred around 260 exp 0 C to 280 exp 0 C. Thus, if the yield of the oil is the main concern the catalysts should be investigated at these two temperatures.
