Amoco Oil Company is investigating a selective catalytic cracking process to convert the Fischer-Tropsch gasoline and wax fractions to high value transportation fuels. The wax feedstock for this program is a commercial sample of Fischer-Tropsch product from Sasol. The wax feedstock readily converts over conventional fluid catalytic cracking (FCC) catalysts (85%+ conversion) to high yields of C(sub 4)-gas and gasoline. The work in this area focuses on the effects of process variables and catalyst types. Some initial wax cracking tests on the pilot plant unit continue. These test results also show high conversion (85%+) of the wax feedstock to light gases and gasoline. The ranking of the three zeolite catalyst types for C(sub 4)-C(sub 5) iso-olefin production is similar to the findings of the small scale screening test program. The catalytic cracking test results from both the small scale test unit and the pilot plant suggest that very mild process conditions and low activity catalysts are needed to lower the overall wax conversion. The target light olefin yields vary with catalyst type and the process conditions.
