Abstract
A method for producing a product comprising at least one selected from C2+ hydrocarbons, oxygenates, and combinations thereof from light gas comprising one or more of carbon dioxide, methane, ethane, propane, butane, pentane, and methanol by forming a dispersion of light gas in a liquid feed, wherein the dispersion is formed at least in part with high shear forces and wherein at least one of the liquid feed and the light gas is a hydrogen source. A system for carrying out the method is also presented.
Claims23
A system for producing a product comprising at least one selected from oxygenates, C2+ hydrocarbons, and combinations thereof, the system comprising:
- a light gas feed consisting essentially of carbon dioxide, methane, ethane, propane, butane, or a combination thereof;
