抄録

A fixed-bed process to convert light paraffins to aromatics was completed, test operated in a demonstration plant. Normally, this reaction is conducted in a continuous or swing type regeneration system to prevent carbon build-up on the catalyst. The new light naphtha aromatization (LNA) process is catalyzed by zinco-aluminosilicate, that has higher activity and extended stability. In a 2250 barrels per day demonstration plant, the process was operated continuously for more than 1000h, attaining over 95wt% conversion and over 50wt% aromatics yield.<br>The demonstration unit consists of two sections, reaction and separation. The former includes three fixed bed reactors arranged with preheaters in series, replacing the conventional heavy naphtha reforming unit. Catalyst regeneration is semi regenerative.<br>The catalyst was discharged from the reactor after regeneration and analyzed for properties and activity. The results indicated that the catalyst is stable, after cyclic operation of reaction and regeneration.
