Abstract:
1. A carbon-to-liquids system comprising: a source of syngas; a first vessel configured to shift the syngas to increase a hydrogen to carbon monoxide ratio (H a source of hydrogen gas coupled in flow communication with the shifted syngas, said source of hydrogen configured to be mixed with said shifted syngas to increase the H a second vessel configured to receive the hydrogen gas and shifted syngas mixture, said second vessel comprising a catalyst configured to facilitate a Fischer-Tropsch synthesis reaction; a hydrogen recovery filter coupled in flow communication with said second vessel and configured to extract hydrogen from an un-reacted hydrogen/shifted syngas mixture to produce a hydrogen-lean syngas, the extracted hydrogen is injected into the shifted syngas to increase the H a lean oil system comprising an absorber and a stripper, said absorber and said stripper coupled in flow communication with said hydrogen recovery filter to process the hydrogen-lean syngas to produce a crude natural gas, a liquefied petroleum gas, and at least one of a high pressure fuel gas, low pressure fuel gas, and purified hydrogen (H an oligomerisation system coupled in flow communication with said lean oil system to produce naphta; and a catalyst regeneration system coupled in flow communication with said oligomerisation system and said second vessel, said catalyst regeneration system configured to recycle naphta received from said oligomerisation system to facilitate catalyst recovery.
