Abstract
A combination operation for upgrading reduced crudes is described which particularly restricts the contact time between hydrocarbons, solid sorbent material and cracking catalyst particles whereby quenching of visbroken product vapors is eliminated, coke formation is substantially restricted and catalytic cracking of hot product vapors of visbreaking contributes to the catalytic cracking thereof in a time-temperature restricted atmosphere providing substantial yields of gasoline and gasoline precursors.
