ABSTRACT:
A process for the anaerobic digestion of organic carbonaceous material is disclosed. The process includes the steps of (a) hydrolyzing organic carbonaceous material to produce a digester stream including hydrolysis products; (b) subjecting the digester stream to a first methanation phase operating at thermophilic conditions to produce a gaseous product including methane; and (c) subjecting the digester stream to a second methanation phase operating at mesophilic conditions to produce further gaseous product including methane, and to recover heat. An apparatus for the anaerobic digestion of organic carbonaceous material is also disclosed.
