摘要：NOVELTY - Preparation of modified molecular sieve comprises adding molecular sieve and nitrate into water, soaking, drying and calcining. USE - Preparation of modified molecular sieve for dimethyl ether synthesis. ADVANTAGE - The bifunctional catalyst made from modified molecular sieve has the activity of current bifunctional catalyst and it can increase the selectivity of reaction target product of dimethyl ether. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for the preparation of bifunctional catalyst for dimethyl ether synthesis comprising mixing the modified molecular sieve with methanol synthesis catalyst, tableting and calcining.
