Amylene alkylation give refiners a two-fold advantage: it increases the volume of alkylate available while decreasing Reid vapor pressure (Rvp) and olefinic content of gasoline blendstocks. Historically, refiners have alkylated butylenes and, in some cases, propylene to form a high octane, low Rvp, paraffinic gasoline blendstock. To reformulate gasoline, refiners may alkylate amylenes as well. EPA's complex model is expected to allow refiners more flexibility in meeting reformulated gasoline targets. The availability of increased volumes of alkylate could, for example, allow a refiner to maintain desired reformer severity. EPA published the final version of the complex model in December 1993. Rvp will be a very important parameter. Relatively small Rvp reductions result in relatively large predicted reductions in VOCs and toxics. Alkylating the C[sub 5] cut from the FCC can significantly reduce the Rvp of the finished gasoline pool. And combined with the addition of MTBE, it can reduce benzene, aromatics, olefin and sulfur levels. Depending on the composition of the refiner's gasoline pool, alkylating amylenes and adding MTBE may meet phase 1 of the complex model. This paper describes the following: alkylate characteristics, amylene alkylation, C[sub 5] data, acid consumption, octane, ASTM D-86 distillations, and alkylating TAME raffinate.
