Abstract: The present disclosure relates generally processes and systems for converting a mixture of light hydrocarbons to liquid transportation fuels by first cracking the light hydrocarbons to an intermediate comprising olefins, which is converted by contacting with a catalyst comprising at least one zeolite in two separate conversion stages with an intervening recovery of liquid product. The first stage conversion favors oligomerization of larger olefins to form diesel range products that are collected prior to directing unconverted smaller olefins to be oligomerized in a second stage conversion conducted at a higher temperature and lower pressure.
