摘要

This article mainly concerns the performance and behavior and investigation of changes in activity and selectivity of Low Si/Al of ZSM-5 to find the best production distribution. The non-promoted catalyst to be compared with the promoted one was a Si/Al = 31.5 H-ZSM-5, tested previously. Wet Impregnation was made using Ultrasonic system combined by special pH control. The results showed how acid sites changed by the TOS and also how products distribution improved in both phases. Also, the results showed how Strontium decreased Gas and increased liquid production. This leads to achieve MTA (Methanol to Aromatics) or MTHC (Methanol to Hydrocarbons) catalyst.
