  • Publication number: 20190055482
    Abstract: An integrated process for increasing olefin production is described through which heavy cracker residues of fluid catalytic cracking unit and steam cracking unit are completely mixed, and mixed stream is properly recycled and further combined with atmospheric tower bottoms. Combined stream is deasphalted and hydrotreated to produce a proper feedstock for steam cracking unit for manufacturing light olefin compounds. The integrated process produces higher amount of light olefins than a substantially similar process without processing the heavy cracker residues.

  • Patent number: 10207255
    Abstract: In an embodiment, a method for making a catalyst, comprises: forming a mixture comprising a germanium source, an alkali metal source, an aluminum source, and a silica source, wherein the mixture has a pH; adjusting the pH of the mixture to a value of greater than or equal to 9.5; crystallizing and calcining the mixture to form a zeolite; depositing platinum on the zeolite; and calcining the zeolite to form the final catalyst. The final catalyst is non-acidic and has an aluminum content of less than or equal to 0.75 wt % based on the total weight of the final catalyst excluding any binder and extrusion aide and a Si:Al2 mole ratio of greater than or equal to 125.

  • Patent number: 8772192
    Abstract: A catalyst and its preparation and use are disclosed. The catalyst is a silicalite having germanium (Ge) included within the framework of the silicalite prepared in a particular manner. The catalyst may be used in a method of converting hydrocarbons wherein a hydrocarbon feed is contacted with the catalyst. The catalyst may be formed by preparing an aqueous reaction mixture of a silica-containing silicalite precursor material and a germanium source. The reactants of the reaction mixture are allowed to react. The reacted reaction mixture is heated under conditions to form crystals of a silicalite having germanium included within the framework of the silicalite. The crystals are then calcined to form the catalyst. In certain embodiments, a noble metal may be deposited upon the germanium-containing silicalite.

  • Publication number: 20110132804
    Abstract: This invention relates to a process for the increasing the octane number of a naphtha hydrocarbon feed having a predominantly paraffin content with a germanium-containing zeolite catalyst. The catalyst is a non-acidic germanium zeolite on which a noble metal, such as platinum, has been deposited. The zeolite structure may be of MTW, MWW, MEL, TON, MRE, FER, MFI, BEA, MOR, LTL or MTT. The zeolite is made non-acidic by being base-exchanged with an alkali metal or alkaline earth metal, such as cesium, potassium, sodium, rubidium, barium, calcium, magnesium and mixtures thereof, to reduce acidity. The catalyst is sulfur tolerant. The hydrocarbon feed may contain sulfur up to 1000 ppm. The present invention could be applicable to a feedstream which is predominantly naphthenes and paraffins.
