  • Patent number: 7304195
    Abstract: A process for increasing the production of benzene from a hydrocarbon mixture. A process for producing an aromatic hydrocarbon mixture and liquefied petroleum gas (LPG) from a hydrocarbon mixture, and a solvent extraction process for separating and recovering polar hydrocarbons from a hydrocarbon mixture containing polar hydrocarbons (that is, aromatic hydrocarbons) and nonpolar hydrocarbons (that is, non-aromatic hydrocarbons) are integrated, thereby it is possible to increase the production of benzene.
    Type: Grant

  • Patent number: 7301063
    Abstract: A process for increasing the production of light olefin hydrocarbons from a hydrocarbon feedstock. A process for producing an aromatic hydrocarbon mixture and liquefied petroleum gas (LPG) from a hydrocarbon mixture, and a process for producing a hydrocarbon feedstock which is capable of being used as a feedstock in the former process, that is to say, a fluidized catalytic cracking (FCC) process, a catalytic reforming process, and/or a pyrolysis process, are integrated, thereby it is possible to increase the production of C2-C4 light olefin hydrocarbons.

  • Patent number: 7297831
    Abstract: Disclosed is a process of preparing aromatic hydrocarbons and liquefied petroleum gas (LPG) from a hydrocarbon mixture, in which a non-aromatic compound in the hydrocarbon feedstock mixture is converted into a gaseous material having a large amount of LPG through hydrocracking, and an aromatic compound therein is converted into an oil component having large amounts of benzene, toluene, and xylene (BTX) through dealkylation and transalkylation, in the presence of a catalyst obtained by supporting platinum/bismuth onto a mixture support having zeolite and an inorganic binder. The gaseous product is separated into LPG and a mixture of methane and ethane depending on differences in boiling point through distillation, while the liquid product is separated into benzene, toluene, xylene, and C9+ aromatic compounds depending on differences in boiling point through distillation.
