.~ Synthesis catalyst, solvent, or component thereof used as agent in hydrocarbon purification or separation {1}
703
.~.~ By interaction with nonhydrocarbon
DEFINITION
Classification: 585/703
By interaction with nonhydrocarbon:
(under subclass 702) Subject matter in which the used or to-be-used catalyst interacts with a nonhydrocarbon to separate the nonhydrocarbon from the hydrocarbon.
(1) Note. The separating action may be "physical", that is, adsorption or dissolving the nonhydrocarbon, or may be "chemical", that is, a reaction with the nonhydrocarbon, catalyzing a reaction of the nonhydrocarbon, etc.
(2) Note. Where the interaction of the catalyst is with both a hydrocarbon component and a nonhydrocarbon component, the patent is placed in subclass 702 and cross-referenced here.
