    摘要: An improved process for alkylation of isoparaffins with olefins to yield a product which includes a high proportion of highly branched alkylates for blending into gasolines. The improved process comprises contacting the isoparaffins and olefins with a catalyst comprising ZSM-20, preferably a HZSM-20 zeolite or a rare-earth cation exchanged ZSM-20 zeolite.

    摘要: The liquid carrier in a Fischer-Tropsch synthesis slurry reactor system is periodically or continually separated and subjected to cracking and isomerization in the presence of suitable catalysts. The treated carrier is returned to the reactor system and the accumulation of high viscosity paraffin in the reactor slurry is minimized. Suitable catalysts include a mixture of cracking and isomerization catalysts. Zeolite ZSM-45 is a novel constituent of the catalyst system.
