Four new aluminophosphate molecular sieves were prepared in test quantities. Chemical modification to increase their catalytic activity is planned. One of these (unmodified), AlPO/sub 4/-11, was tested and found rather inactive for propylene oligomerization. Appendix A reports synthesis work on both Task 1 and Task 2 catalysts. Data from seven tests of propylene oligomerization with several catalysts are reported in Appendix C. Changing from methanol to propylene feed eliminated earlier problems associated with the solid part of methanol reaction products. Tests with UCC-101, a proprietary UCC, large pore molecular sieve of moderate acidity, resulted in reaction products having both gasoline and diesel fractions. Tests with LZ-105-6, similar in properties to Mobil's ZSM-5, resulted in good yield of gasoline range product with very little diesel range product. Feeding water along with the propylene and hydrogen was found to markedly reduce the rate of deactivation of both LZ-105 and UCC-101. Another new UCC proprietary molecular sieve, UCC-104, was active and very selective for the production of gasoline range hydrocarbons (more than 95% selective to C/sub 5//sup +/). At low temperatures, the UCC-104 produces less propane than the LZ-105-6, i.e., the UCC-104 is more selective to liquid product formation than catalysts like ZSM-5. Results of seven Task 2 tests appear in Appendix C. In four runs the catalysts had reasonable activity but were not as selective to liquid products as desired.
