Abstract

The digestibility of cellulosic plant matter to ruminants is increased by mixing the particulate matter with water, an acid catalyst selected from carbonic, sulphuric, phosphoric, hydrochloric and acetic acids to give a pH of 3 and a metal catalyst selected from iron, ferric chloride, ferric sulphate, ferric nitrate, manganese and non-toxic manganese salts, subjecting the mixt. to an oxygen partial pressure of about 20-30 psig at about 105 degrees-110 degrees C for 12-20 mins., blowing off resulting gases of oxidation and hydrolyzing the resulting oxidized mixt. at elevated temp. e.g. 180 degrees c, and 135-150 psig pressure under satd. steam conditions. In the oxidn. at least a portion of the lignin-cellulose bonds are broken and at least a portion of the cellulose molecules fragmented, and in the hydrolysis at least a portion of the cellulose is converted into saccharides and saccharide acids. The process may be applied to matter such as corncobs, rice halls, bagasse, wheat straw, oat straw, rice straw and the trunks, limbs, stems and leaves of tree and shrubs. This is less specific regarding the nature of the acid and metal catalysts and the timeS, pressures and temperatures.
