Chen, N Y; Pelrine, B P

A process is described for hydrodewaxing feedstocks containing wax components which causes the feedstock to be characterized as high-pour. The process comprises contacting the feedstock in liquid form, under hydrodewaxing conditions, includes elevated temperature, with a catalyst composition in a reaction zone wherein the catalyst composition comprises a zeolite having a constraint index within an approximate range of about 1 to 12 and having an alpha-value of about 1 to about 10; maintaining the catalyst in the liquid feedstock and subjecting the liquid feedstock to agitation equivalent to from 50 to 500 rpm, while allowing products of hydrodewaxing, produced under the hydrodewaxing conditions, to volatize, from the reaction zone, to produce a product of at least substantially constant pour joint which is less than that of the feedstock.
