Abstract: A VERTICAL DOWNFLOW REACTOR FOR CONTACTING A TWO-PHASE, VAPOR-LIQUID REACTION MIXTURE WITH SOLID CATALYST CONTAINED IN ONE OR MORE REACTOR VESSEL CATALYST ZONES. MEANS ARE PROVIDED IN THE UPPER PORTION OF SUCH VERTICAL RACTOR TO SEPARATE ANY SOLID PARTICULATE CONTAMINANTS FROM SAID REACTION MIXTURE PRIOR TO ADMITTING THE REACTION MIXTURE INTO A REACTOR VESSEL CATALYST ZONE. MEANS ARE ALSO PROVIDED FOR EVENLY DISTRIBUTING VAPOR AND LIQUID COMPONENTS OF THE REACTION CHARGE MIXTURE ACROSS THE HORIZONTAL CROSSSECTIONAL AREA OF A REACTOR VESSEL CATALYST ZONE.

Abstract: EFFFLUENTS FROM A FIRST CATALYST ZONE AND QUENCH FLUID TO FROM A NEW TWO-PHASE VAPOR-LIQUID REACTION MIXTURE AND REACTOR INTERNAL PARTS FOR EVELY REDISTRIBUTING THE NEW REACTION MIXTURE ACROSS THE TOP HORIZONTAL CROSS-SECTION OF A SECOND CATALYST ZONE.

A VERTICAL, DOWNFLOW REACTOR FOR CONTACTING A TWO-PHASE VAPOR-LIQUID REACTION MIXTURE WITH SOLID CATALYST CONTAINED IN TWO OR MORE REACTOR VESSEL CATALYST ZONESS, WHEREIN SUCH REACTOR HAS MEANS FOR INJECTING QUENCH FLUID BETWEEN SUCCEEDING CATALYST ZONES. SUCH REACTOR COMPRISES REACTOR INTERNAL PARTS LOCATED INTERMEDIATE TO TWO CATALYST ZONES FOR INTIMATELY MIXING VAPOR AND LIQUID REACTION

Abstract: A process for manufacturing high octane gasoline from a low octane paraffinic naphtha, which comprises hydrocracking a first portion of the naphtha to yield a C4 fraction comprising isobutane and a hydrocracked light naphtha fraction having a relatively high octane number, catalytically cracking a second portion of the naphtha to yield a C3-C4 fraction comprising propylene, butylenes and isobutane and a catalytically cracked light naphtha fraction having a relatively high octane number, and reacting, in an alkylation zone the hydrocracked C4 fraction and the catalytically cracked C3-C4 fraction to yield a high octane gasoline alkylate. The proportion of naphtha charged to the hydrocracking zone and the catalytic cracking zone are adjusted such that isobutane, butylene and propylene charge to the alkylation zone are in stoichiometric balance.
