New practice of diameter-transformed fluidized bed reactor in the petrochemical industry
Motor gasoline standards are becoming increasingly stringent—in particular, the olefins content requirement in motor gasoline is getting lower and lower. Among these standards, China standard motor gasoline VI (B) requires that the olefin content should be < 15 vol%.
Reduce dry gas and coke with a more flexible FCC technology
To meet increasingly stringent specifications for cleaner gasoline and to produce more clean fluid catalytic cracking (FCC) naphtha with lower olefins, a novel FCC technologya for maximizing isoparaffins was developed in the late 1990s. The technology’s principal is based on the formation and conversion of olefins in two different reaction zones.
Consider new processes for clean gasoline and olefins production
Advanced technologies promote propylene yield while reducing olefins in gasoline
