Barr, F T

This patent describes a process of producing gas mixtures containing carbon monoxide and hydrogen by subjecting carbonizable materials to a low-temperature carbonization in the form of a dense turbulent bed of finely divided carbonaceous solids. These solids are fluidized by an upwardly flowing gas in a carbonization zone at temperatures around 1000/sup 0/F, which is conducive to substantial cracking of carbonization products boiling above about 700/sup 0/F. This process will produce volatile carbonization products and highly reactive coke having an activity of about T/sub 15/ = 200/sup 0/C and about T/sub 25/ = 245/sub 0/C. The process continues by separating tar fractions above about 700/sup 0/F from the volatile products, returning said fractions to said carbonization zone substantially in the liquid state to be converted therein into lower boiling volatile products and highly reactive coke of said activity. It ends by contacting said highly reactive coke directly with a gasifying medium consisting essentially of steam in a separate gasification zone at gasification conditions adapted to produce said gas mixtures.
