Alkylation of isobutane with C3--C4 olefins---identification and chemistry of heavy-end production. L.F. Albright and K.V. Wood. Ind. Engng. Chem. Res., June 1998, 37(6), 2110--2120.
The composition of refinery produced alkylates is determined using a gas chromatographic technique. These products often contain 10 to 16% of heavy-end isoparaffins in the C10--C16 range when isobutane is alkylated with C3--C4 olefins using H2SO4 or HF as catalysts. These heavy isoparaffins can have a significant effect on octane number if they are included in gasoline engine fuels. Results show that the amount and composition of the C10 and heavier isoparaffins varies significantly with olefin feed and operating conditions. The analytical technique described is used to optimize alkylation processes. 13 refs.
