重炭化水素の接触式熱分解によるエチレンおよびプロピレンの製造プロセス
Document Type and Number:
Japanese Patent JP4590435
Kind Code:
B2
Abstract:
A catalytic pyrolysis process for production of ethylene and propylene from heavy hydrocarbons, comprises that heavy hydrocarbons are contacted with a pillared interlayered clay molecular sieve and/or phosphorus and aluminum or magnesium or calcium modified high silica zeolite having a structure of pentasil contained catalysts in a riser or downflow transfer line reactor in the presence of steam and catalytically pyrolysed at a temperature of 650 DEG C to 750 DEG C and a pressure of 0.15 to 0.4MPa for a contact time of 0.2 to 5 seconds, a weight ratio of catalyst to feedstock of 15:1 to 40:1 and a weight ratio of steam to feedstock of 0.3:1 to 1:1. The yields of ethylene and propylene by the present invention are over 18wt%.
