An ASG system for polygeneration with CC includes a devolatilizer that pyrolyzes solid fuel to produce char and gases. A burner adds exothermic heat by high-pressure sub-stoichiometric combustion, a mixing pot causes turbulent flow of the gases to heat received solid fuel, and a riser micronizes resulting friable char. A devolatilizer cyclone separates the micronized char by weight providing micronized char, steam and gases to a gasifier feed and oversized char to the mixing pot. An indirect fluid bed gasifier combustion loop includes a gasifier coupled to the gasifier feed, a steam input to provide oxygen for gasification and to facilitate sand-char separation, and an output for providing syngas. A burner provides POC to a mixing pot which provides hot sand with POC to a POC cyclone via a riser, where the POC cyclone separates sand and POC by weight and provides POC and sand for steam-carbon reaction.

Char preparation system and gasifier for all-steam gasification with carbon capture

Various embodiments disclosed relate to cooling shale gas via reaction of methane, light hydrocarbons, or a combination thereof, with water. In various embodiments, the present invention provides a method of cooling syngas. The method includes contacting the hot syngas with methane or light hydrocarbons. The hot syngas includes water and has a temperature of about 800&#xb0; C. to about 3000&#xb0; C. The contacting is effective to endothermically react the methane or light hydrocarbons with the water in the hot syngas to form carbon monoxide and hydrogen and to provide a cooled syngas having a lower temperature than the hot syngas.
