  • Process for the preparation of clean fuel and aromatics from hydrocarbon mixtures catalytic cracked on fluid bed
    Patent number: 8933283
    Abstract: This invention relates to a petroleum refining method for producing high value-added clean petroleum products and aromatics (Benzene/Toluene/Xylene) together, by which low pollution petroleum products including liquefied petroleum gas or low-sulfur gas oil and aromatics can be efficiently produced together from a fluid catalytic cracked oil fraction.

  • Process for increasing production of benzene from hydrocarbon mixture
    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.

  • Process for increasing production of light olefin hydrocarbon from hydrocarbon feedstock
    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.

  • Process for separating normal paraffins from hydrocarbons and applications for the separated hydrocarbons
    Patent number: 6870073
    Abstract: There is provided with a process for separating normal paraffins from hydrocarbons of C5-10 using zeolite molecular sieve 5A, which comprises the steps of (a) selective adsorption (b) cocurrent purge (c) countercurrent desorption. The present process employs butane for purge and desorption step to achieve excellent desorption efficiency and recycles butane in liquid phase to reduce the investment cost. The optimum operating conditions for feedstock change and adsorption capacity reduction are determined by NIR system for on-line monitoring and control. The separated normal paraffins can be efficiently applied to raw material for ethylene production and the separated non-normal paraffins can be efficiently applied to raw material for aromatic hydrocarbons production.
