Abstract: The disclosure relates to olefin oligomerization processes and related zeolites and structure directing agents. The olefin oligomerization processes can exhibit relatively high conversions. The zeolites can exhibit comparatively high stabilities. The zeolites can have relatively high ratios of external surface area to total surface area. An exemplary zeolite is a beta zeolite having a relatively high ratio of external surface area to total surface area. The disclosure also relates to structure directing agents, and methods of using the structure direction agents to prepare the zeolites.

Abstract: A process for producing a monoalkylated benzene comprises contacting benzene with a mixture comprising dialkylated and trialkylated benzenes in the presence of a transalkylation catalyst composition under transalkylation conditions effective to convert at least part of the dialkylated and trialkylated benzene to monoalkylated benzene, wherein the catalyst composition comprises a metallosilicate zeolite comprising openings defined by 14-membered rings of tetrahedrally coordinated atoms and the transalkylation conditions include a temperature in the range of 160° C. to 220° C.
