Thread Content

Recently, a research team from the Shanghai Research Institute of Petrochemical Technology developed a clean production technology for catalysts used in the vapor-phase alkylation of benzene to produce ethylbenzene, which can effectively reduce the emission of \"three wastes\" during the catalyst production process. The research team successfully synthesized high-crystallinity, small-grain ZSM-5 molecular sieves under sodium-free conditions, reducing the amount of template used by over 70% and eliminating the ammonium exchange step; producing 1 ton of catalyst can prevent the generation of 60 tons of ammonia-containing wastewater. This technology underwent industrial pilot testing in September this year, completing the entire production process for producing ethylbenzene via benzene alkylation using a cleaner catalyst method; it took only one and a half years from laboratory research to industrial production.
