Abstract
A process is disclosed for converting distillate to gasoline-range hydrocarbons using a two-stage catalyst system including a first catalyst containing platinum, palladium, or platinum and palladium, and an acidic support, and a second catalyst containing iridium and an inorganic oxide support, and optionally nickel.
Claims19
A process for maximizing octane by converting a low octane distillate feedstream to a high octane gasoline-range hydrocarbons comprising:
- a) contacting the low octane distillate feedstream, in a first reaction zone, with a first catalyst comprising a metal component selected from the group consisting of platinum, palladium, and combinations thereof, and an acidic support in the presence of hydrogen to produce an intermediate product;
- and
- b) contacting said intermediate product, in a second reaction zone, with a second catalyst comprising iridium and an inorganic oxide support to produce a high octane gasoline-range product.

- a) contacting the low octane distillate feedstream, in a first reaction zone, with a first catalyst comprising a metal component selected from the group consisting of platinum, palladium, and combinations thereof, and an acidic support in the presence of hydrogen to produce an intermediate product,
- wherein said first reaction zone includes a temperature in the range of from about 220° C. to about 260° C., a pressure in the range of from about 200 psig to about 300 psig, and a WHSV for said low octane distillate feedstream of about 0.1 to about 10 hr.−1;
- and
- b) contacting said intermediate product, in a second reaction zone, with a second catalyst comprising iridium and an inorganic oxide support to produce a high octane gasoline-range product, wherein said second reaction zone includes a temperature in the range of from about 280° C. to about 330° C., a pressure in the range of from about 200 psig to about 300 psig, and a WHSV of from about 0.1 to about 10 hr.−1.
