Selective sorption by zeolites
Patent
·
OSTI ID:6609174
An improved adsorptive separation process by the selective sorption properties of certain members of a novel class of zeolites is provided. The novel class of zeolites is characterized by a silica to alumina mole ratio greater than 12 and a Constraint Index within the approximate range of greater than 2 to about 12. The process of this invention involves selective separation of waxy paraffinic compounds in admixture with stocks containing paraffinic compounds, e.g. crude oils, heavy oils, distillate oils and lube base oils, by contacting the mixture with a zeolite having a SiO/sub 2//Al/sub 2/O/sub 3/ mole ratio of at least about 12 and a Constraint Index within the range of greater than 2 to about 12 to effect the selective sorption of said waxy paraffinic compounds by said zeolite.
