摘要:
A method of stabilizing a catalyst for the conversion of aromatic hydrocarbons in the presence of hydrogen such as the isomerization of C.sub.8 aromatic hydrocarbons to increase the content of p-xylene, is carried out by contacting a catalyst in advance of start-up with hydrocarbons in the liquid phase at a temperature preferably of about 50.degree. to about 250.degree. C. and preferably at elevated pressure up to about 50 Kg/cm.sup.2 in the absence of hydrogen; the catalyst being prepared by the acid leaching of a hydrogen form mordenite to produce a mordenite having a silica to alumina molar ratio of about 15 to 21. Preferably, the hydrocarbons used for the contacting have the composition of the feed to be converted.
摘要:
A C.sub.8 aromatic hydrocarbon mixture which typically may consist essentially of xylenes and ethylbenzene, the latter being present in an amount of not more than 40 weight percent, is converted to a product containing an increased proportion of p-xylene by bringing it into contact with an acid leached hydrogen form mordenite having a silica to alumina mole ratio of 15-21 at a temperature in the range of 180.degree. to 250.degree. C. under a pressure of atmospheric to 200 Kg/cm.sup.2. Hydrogen may be present in the system in a mole ratio of hydrogen to C.sub.8 aromatic hydrocarbon mixture of 0-10.
