Extraction Process - an overview | ScienceDirect Topics

Extraction Process. The extraction process frequently consists of a steam reforming step in which a carbon-bearing feed stock is transformed into a syngas or reformate consisting mainly of H2 and CO, followed, when necessary, by a shift reaction in which the CO in the reformate is made to react with additional water and is transformed into H2 and CO2.
