Dual stage light alkane conversion to fuels

A system for converting light hydrocarbon feedstock to produce liquid transportation fuels, the system comprising:

• a supply of light hydrocarbon feedstock comprising at least one C3-C5 alkane;
• a first-stage conversion reactor operable to receive the light hydrocarbon feedstock and facilitate contact between the light hydrocarbon feedstock and a first fixed-bed catalyst, the first-stage conversion reactor further operable to maintain a first temperature in a range from 400 degrees Celsius to 650 degrees Celsius and a first pressure in a range from 0 psig to 100 psig;
• a first separator operable to receive and partially condense a first effluent from the first-stage conversion reactor, the first separator further comprising an outlet for a first condensed hydrocarbon liquid comprising at least five carbon atoms and an outlet for a first gas phase product comprising at least one C2-C4 olefin;
• a second-stage conversion reactor operable to receive the first gas phase product from the first separator and facilitate contact between the first gas phase product and a second fixed-bed catalyst, the second-stage conversion reactor further operable to maintain a second temperature in a range from 200 degrees Celsius to 400 degrees Celsius and a second pressure in a range from 0 psig to 500 psig;
• and
• a second separator operable to receive and partially condense a second effluent from the second-stage conversion reactor, the second separator further comprising an outlet for a second condensed liquid hydrocarbon comprising at least one five carbon atoms and an outlet for an unconverted gas comprising at least one C3-C4 alkane.
