Two processes which can be integrated to simultaneously improve gasoline quality and quantity are reviewed. The first process to upgrade the quality of the butene stream produced in the refinery was improved through a study of the variables, operating temperature, operating pressure, space time, butadiene concentration in feedstock, and hydrogen concentration, that affect the simultaneous catalytic hydrogenation of butadiene and complete isomerization of butene-1 to butene-2. The second process studied was the use of the methyl-tert-butyl ether (MTBE) section in which the product from the hydroisomerization section of the system is fed to the MTBE section of the system producing a high octane quality ether suitable for gasoline blending. The effects of the following variables on the MTBE process were determined: operating temperature, operating pressure, space time, methanol/-isobutylene feed mole ratio, recycle rates of products, and reactor configuration. Pilot plant data are presented for the evaluation of the hydrogen/isobutene and sulfuric acid alkylation processes. Butene-2 was found to be the preferred feedstock for the hydrogen/isobutene process. Isobutylene was found to yield an alkylate inferior to either 1-butene or 2-butene, regardless of which alkylation process was used. (BLM)
