Low pressure xylene isomerization |
摘要 |
Long on-stream periods of low pressure, vapor phase isomerization of xylenes is achieved in a system having tolerance of ethyl benzene in the charge by using a zeolite catalyst such as zeolite ZSM-5 at partial pressure of eight carbon atom aromatics below 100 pounds per square inch and temperature of 500 DEG F. to 800 DEG F.
