6.2.5 COS Hydrolysis | netl.doe.gov

Most of the sulfur in the coal is converted to hydrogen sulfide (H2S) during gasification. However, depending on the gasification temperature and moisture content, approximately 3 to 10% of the sulfur is converted to carbonyl sulfide (COS). In applications where very low sulfur (< 10 ppmv) syngas is required, converting COS to H2S before sulfur removal may be necessary, because most current .

Ethanol From Cellulose: A General Review

Starchy materials require a reaction of starch with water (hydrolysis) to break down the starch into fermentable sugars (saccharification). Typically, hydrolysis is performed by mixing the starch with water to form a slurry which is then stirred and heated to rupture the cell walls. . or freezing—all of which require high-energy consumption .

Hydrolysis of cellulose to glucose by solid acid catalysts .

As the main component of lignocelluloses, cellulose is a biopolymer consisting of many glucose units connected through β-1,4-glycosidic bonds. Breakage of the β-1,4-glycosidic bonds by acids leads to the hydrolysis of cellulose polymers, resulting in the sugar molecule glucose or oligosaccharides. Mineral acids, such as HCl and H 2 SO 4, have been used in the hydrolysis of cellulose.
