Production of monoaromatic hydrocarbons from hydrocarbon feedstocks

A process for converting a feedstock comprising dicyclopentadiene to monoaromatic hydrocarbons, the process comprising:

• contacting the feedstock with a first catalyst being a hydrocracking catalyst in the presence of hydrogen in a hydrocracking reaction zone at a pressure of 500 to 3,500 kilopascals, a temperature of 200 to 500° C., and a liquid hourly space velocity of 0.5 to 6 hour 1 to convert at least a portion of the dicyclopentadiene to monoaromatic hydrocarbons, and provide an intermediate product stream comprising the monoaromatic hydrocarbons converted from the dicyclopentadiene, indene or a derivative thereof, naphthalene or a derivative thereof, or a combination comprising at least one of the foregoing, wherein the hydrocracking catalyst comprises
• a zeolite support having an average pore diameter of 5 to 13 nanometers, and
• greater than 3 to 15 weight percent of molybdenum, tungsten, nickel, cobalt, platinum, palladium, or a combination comprising at least one of the foregoing impregnated on the zeolite support, based on a total weight of the hydrocracking catalyst;
• and
• contacting at least a portion of the intermediate product stream with a second catalyst being a selective ring opening catalyst in the presence of hydrogen in a selective ring opening reaction zone at a pressure of 1,000 to 15,000 kilopascals and at a temperature of 100 to 700° C. to convert at least a portion of the indene or a derivative thereof, naphthalene or a derivative thereof, or a combination comprising at least one of the foregoing to additional monoaromatic hydrocarbons, wherein the selective ring opening catalyst comprises
• a zeolite support having a silica to alumina molar ratio of 25 to 100, and
• 0.01 to 20 weight percent of a metal impregnated on the zeolite support of the selective ring opening catalyst, based on a total weight of the selective ring opening catalyst, wherein the metal comprises molybdenum, tungsten, nickel, cobalt, platinum, palladium, or a combination comprising at least one of the foregoing,
• wherein the feedstock comprises the dicyclopentadiene in an amount of greater than 35 weight percent, based on a total weight of the feedstock.

An integrated process for converting a feedstock comprising dicyclopentadiene to monoaromatic hydrocarbons, the process comprising:

• contacting the feedstock with a first catalyst being a hydrocracking catalyst in the presence of hydrogen in a hydrocracking reaction zone to convert at least a portion of the dicyclopentadiene to monoaromatic hydrocarbons, and provide an intermediate product stream comprising the monoaromatic hydrocarbons converted from the dicyclopentadiene, indene or a derivative thereof, naphthalene or a derivative thereof, or a combination comprising at least one of the foregoing, wherein the hydrocracking catalyst comprises
• a zeolite support having an average pore diameter of 5 to 13 nanometers, and
• greater than 3 to 15 weight percent of molybdenum, tungsten, nickel, cobalt, platinum, palladium, or a combination comprising at least one of the foregoing impregnated on the zeolite support, based on a total weight of the hydrocracking catalyst;
• and
• contacting at least a portion of the intermediate product stream with a second catalyst being a selective ring opening catalyst in the presence of hydrogen in a selective ring opening reaction zone to convert at least a portion of the indene or a derivative thereof, naphthalene or a derivative thereof, or a combination comprising at least one of the foregoing to additional monoaromatic hydrocarbons,
• wherein the hydrocracking reaction zone and the selective ring opening reaction zone are within a single reactor,
• wherein the feedstock comprises the dicyclopentadiene in an amount of greater than 35 weight percent, based on a total weight of the feedstock.
