Abstract: A hydrocarbon source feed is upgraded using a solvent deasphalting (SDA) unit employing a solvent having a critical temperature T.sub.c by initially separating from a first hydrocarbon input stream fractions with an atmospheric equivalent boiling temperature less than about T.sub.f .degree. F. for producing a stream of T.sub.f.sup.- fractions and a residue stream (T.sub.f.sup.+ stream), where T.sub.f is greater than about T.sub.c -50.degree. F. In the SDA unit, a second hydrocarbon input stream which includes the residue stream is deasphalted for producing a first product stream of substantially solvent-free asphaltenes, and a second product stream containing substantially solvent-free deasphalted oil (DAO). The source feed may be included in either the first or second input streams. The DAO in the second product stream is thermally cracked for producing an output stream that includes thermally cracked fractions and by-product asphaltenes produced by thermally cracking the DAO.

Abstract: A process for thermally and catalytically upgrading a heavy feed in a single riser reactor FCC unit is disclosed. A heavy feed is cracked in the base of the riser at higher than normal cracking temperatures for at least 1.0 seconds of vapor residence time, then quenched. Quenching with large amounts of quench, preferably downstream of the mid point of the riser, increases conversion as compared to use of the same amount of quench within one second. Small amounts of quench, near the riser outlet, crack heavy feed roughly as well as large amounts of quench, near the base of the riser. High velocity, atomizing quench nozzles reduce riser pressure and/or catalyst slip in downstream portions of the riser, further increasing gasoline selectivity and reducing coke yields.
