Catalytic dewaxing process for the production of high VI lubricants in enhanced yield |
摘要 |
A catalytic hydrodewaxing process is described for producing liquid hydrocarbon lubricant base stock from liquid hydrocarbon feedstock in greater yield and viscosity index equivalent to solvent dewaxing methods. The process involves contacting a feedstream comprising hydrogen and the hydrocarbon feedstock with shape selective metallosilicate catalyst particles under hydrodewaxing conditions sufficient to produce a base stock having a predetermined viscosity index without regard to the base stock pour point temperature produced by the process. Pour point depressants are added to the base stock to lower the pour point temperature of the base stock to a predetermined temperature.
