Xylenes and Benzene Process by China Petrochemical Technology

The S-TDT process can produce mixed xylenes and benzene in an aromatics complex through disproportionation of toluene and transalkylation of toluene and C9+ aromatics (C9+ A) using toluene and C9+ A as feedstocks. The commercially proven HAT series catalysts are … Continue reading
