Cation promotion effects in zeolite-supported F-T catalysts. Fourth quarterly report, June 1984-August 1984. [Cyclopropane]
During this quarter, June 1, 1984, to August 31, 1984, investigations focussed on two main tasks CO hydrogenation and cyclopropane hydrogenation. CO hydrogenation have been performed at atmospheric pressure and in the temperature range 220 to 300/sup 0/C. The catalysts used were Ru supported on the following zeolites: NaY, LiY, KY, CsY, RbY, HY, NaX and KL. All catalysts have been analyzed by atomic absorption and found to contain 3 +- 0.1 wt% Ru. The following features are discussed in this report: activity and selectivity; dependence of the olefin fractions upon the nature of the support; and relationship between the composition of C/sub 4/ fractions and the support acidity. Another microreactor system has been constructed for performing cyclopropane hydrogenation over a series of 0.15 wt % Ru/zeolites. 5 references.
