  • Publication number: 20220306947
    Abstract: Embodiments of the disclosure include processes for ring-opening of hydrocarbon species comprising aromatic and cycloparaffinic rings in hydrocarbon feeds to produce ring-opened products. In particular, the process comprises contacting hydrocarbon species comprising aromatic and cycloparaffinic rings with hydrogen in the presence of a ring-opening catalyst comprising a noble metal on a low-acidity crystalline material containing external pockets to facilitate ring-opening of the hydrocarbon species comprising aromatic and cycloparaffinic rings. The processes are useful in the transformation of polynuclear aromatic hydrocarbons (PAHs) to ring-opened products.

  • Patent number: 11389788
    Abstract: Provided is a scalable delamination of a SSZ-70 framework zeolite, without the need for sonication, which has been previously made difficult by the charged nature of the imidazolium structure-directing agents that are required for zeolite synthesis. The method comprises contacting a B-SSZ-70 zeolite precursor with a zinc source such as zinc nitrate and a fluoride source.

  • Publication number: 20220213394
    Abstract: Embodiments of the disclosure include processes for selective ring-opening of cycloparaffins in hydrocarbon feeds to produce hydrocracked cycloparaffins. In particular, the process comprises contacting a hydrocarbon feed comprising cycloparaffins with hydrogen and a catalyst comprising an unsulfided, low-acidity, metal-containing zeolite under hydrocracking conditions; wherein the metal is selected from the group consisting of platinum, nickel, rhodium and mixtures thereof. The processes are useful for upgrading petroleum streams to lubricant base stocks.
