ABSTRACT:

In the fifteenth quarter work continued for two major tasks: (1) Slurry Catalyst Development, and (2) Catalyst A Development. For task one, parametric gas phase screening tests were concluded on a ''modified'' conventional catalyst and an optimum preparation and activation procedure chosen for diesel fuel selectivity. A short term slurry test of this catalyst showed promising results. Further work in modifying the composition of this catalyst may be worthwhile. Two tests were conducted on Catalyst A this quarter: (1) A test to determine the effect of air calcination pretreatment. At the same process conditions, the bulk activity was nearly three times that of the uncalcined batch of this catalyst. The diesel fuel fraction, however, was considerably lower. (2) A retest of a modified version of this catalyst, A'. The results of this test indicte that: the selectivity of A' is highly dependent on the CO/H sub 2 ratio; temperature affects both the activity and product selectivity (a 15% increase in bulk activity and a shifting of products into the lower molecular weight region resulted from an increase in temperature from 240 to 260 deg C); and reproducibility of lower temprature results are not possible after extended testing at a higher temperature level indication that the performance of the catalyst is dependent on its history of operating conditions. A number of gas phase activation procedures were tested on Catalyst A'. No appreciable difference in activity and selectivity was observed. A test of air calcination pretreatment before gas phase activation, however, resulted in an appreciable increase in bulk activity and increase in the yield of gasoline fuel. (ERA citation 11:005022)
