In collaboration with Jiangsu Sopo Co. and China Wuhuan Engineering, the technology is based on molecular sieve membrane dehydration technology and leads to 99,6 % pure ethanol. China’s acetic acid production capacity is more than ten million tons per year, but a weak value chain for downstream products such as acetate, vinyl acetate, terephthalic acid, acetic anhydride led to the concept for hydrogenation of acetic acid to ethanol.
