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.

Claim (Index 1):
A method for converting a light hydrocarbon feedstock to produce liquid transportation fuels, the method comprising:\n a) providing a light hydrocarbon feedstock comprising at least 80 wt % of hydrocarbon molecules that contain five or less carbon atoms; b) cracking and quenching the light hydrocarbon feedstock to produce a raw cracked olefins stream comprising ethylene, propylene, butenes, acetylene and dienes, hydrogen, methane and unconverted feedstock; b) contacting the raw cracked olefins stream with a first stage catalyst, wherein the catalyst, temperature and pressure in the first stage conversion reactor  25  are configured to produce a first stage effluent comprising at least 10 wt % of hydrocarbons that are characterized by a boiling point ranging from 193\u00b0 C. to 360\u00b0 C. at 1 atm; c) separating the first stage effluent in a first separator to produce a first condensed liquid hydrocarbons comprising at least five carbon atoms, and an unconverted light olefin stream comprising four or less carbon atoms; d) converting the uncondensed gas-phase hydrocarbons in a second stage reactor at a second temperature that is at least 20\u00b0 C. higher than the first temperature, to produce a second stage effluent; e) separating the second stage effluent in a second separator to produce an unconverted light olefin stream comprising four or less carbon atoms, and a second condensed liquid hydrocarbons comprising at least five carbon atoms.
