ABSTRACT:

The objective of this project is to investigate three possible routes to the formation of ethers, in particular methyl tert-butyl ether (MTBE), during slurry phase Fischer-Tropsch (FT) reaction. The three reaction schemes to be investigated are: Addition of isobutylene during the formation of methanol and/or higher alcohols directly from CO and H2 during slurry-phase Fischer-Tropsch; addition of isobutylene to FT liquid products including alcohols in a slurry-phase reactor containing an MTBE or other acid catalyst; and addition of methanol to slurry phase FT synthesis making iso-olefins. Work conducted during the second quarter has concentrated in two specific areas: (1) the construction of a laboratory-scale bubble column slurry reactor (BCSR) for use in the study of each of the three routes defined above, and (2) initial selection, characterization and screening of zeolite catalysts for schemes 1 and 2 above. The design of the reactor was completed in the last quarter and its design described in Quarterly Report No. 1. Various catalysts suitable for reaction schemes 1 and 2 have been identified. 4 figs., 9 tabs.
