摘要
A process for post synthesis treatment of ZSM-5 catalyst for converting ethylene to liquid fuel products providing substantially improved catalyst life. The treatment comprises either a base treatment, an acid treatment or a two-step treatment where one is with an acid and the other is with a base. The base treatment is provided by a weak sodium hydroxide such as less than 1 Molar concentration. The acid treatment is stronger acid where, for example, a hydrogen chloride solution at greater than 2 Molar concentration is used.
