  • Production of high viscosity index lube base oils
    Patent number: 8524069
    Abstract: The invention below shows a preferred method to make high quality base oil at unexpectedly high yields using a combination of hydrotreatment of high waxy feedstocks accompanied by hydroisomerization of the resulting wax to produce an extra high VI lube of greater than 140VI and at least ?18 deg C. pour point or less. The preferred combinations of conditions identified below can surprisingly lead to unexpectedly high yields. This allows the use of higher oil content (or lower wax content) feedstocks.
    Type: Grant

    Date of Patent: September 3, 2013
    Assignee: ExxonMobil Research and Engineering Company

  • Catalytic Dewaxing Process
    Publication number: 20110180453
    Abstract: In a catalytic dewaxing process, a catalyst comprising from 40 to 80 wt % of ZSM-48 having a silica to alumina molar ratio of less than 200:1 and from 0.3 to 1.5 wt % of a metal or metal compound from Groups 8 to 10 of the Periodic Table of the Elements is provided in a reaction zone. The catalyst is periodically contacted in the reaction zone under dewaxing conditions with a first hydrocarbon feedstock having a wax content of less than 50 wt % and with a second hydrocarbon feedstock having a wax content of 50 wt % or more.

  • Process for producing gasoline of increased octane and hydrogen-containing co-produced stream
    Publication number: 20100155300
    Abstract: The present invention is directed to a process for producing an increased yield of gasoline of increased octane rating by the integration of a membrane separation processing step into the gasoline production process. The integrated process also increases hydrogen production from the reformer.
