Thomson - Web page: https://patentgrep.com/patent/US5326922A ## CPC - C07C 5/52: with a hydrocarbon as an acceptor, e.g. hydrocarbon disproportionation, i.e. 2CnHp -> CnHp+q + CnHp-q - C07C 2/58: Catalytic processes - C07C 2529/70: of types characterised by their specific structure not provided for in groups C07C2529/08 - C07C2529/65 - C07C: ACYCLIC OR CARBOCYCLIC COMPOUNDS ## Abstract The transfer of hydrogen from a paraffin to an olefin is carried out in the presence of, as catalyst, MCM-36. Especially when the paraffin reactant is an isoparaffin, the olefin produced from the reacted isoparaffin may react with unreacted isoparaffin to also produce an alkylate product. ## Claims ### Claim 1 A process for transferring hydrogen from a paraffin to an olefin, said process comprising contacting said paraffin and said olefin under sufficient hydrogen transfer conditions, said paraffin and said olefin being contacted with a catalyst comprising MCM-36, said MCM-36 being a pillared, layered material having the X-ray diffraction pattern of Table 6. ### Claim 2 (depends on 1) A process according to claim 1, wherein the layers of the MCM-36 have a composition comprising the molar relationship X.sub.2 O.sub.3 :(n)YO.sub.2, wherein n is at least about 5, X is a trivalent element and Y is a tetravalent element, said MCM-36 having the X-ray diffraction pattern of Table 7. ### Claim 3 (depends on 2) A process according to claim 2, wherein X is selected from the group consisting of aluminum, boron, gallium and combinations thereof and Y is selected from the group consisting of silicon, germanium and combinations thereof. ### Claim 4 (depends on 2) A process according to claim 2, wherein X comprises aluminum and Y comprises silicon. ### Claim 5 (depends on 1) A process according to claim 1, wherein the paraffin contains from 4 to about 8 carbon atoms and the olefin contains from 2 to 12 carbon atoms. ### Claim 6 (depends on 1) A process according to claim 1, wherein the paraffin is isobutane. ### Claim 7 (depends on 1) A process according to claim 1, wherein the mole ratio of total isoparaffin to total olefin is from about 1:2 to about 500:1. ### Claim 8 (depends on 1) A process according to claim 1, wherein the mole ratio of total paraffin to total olefin is from about 5:1 to about 100:1. ### Claim 9 (depends on 1) A process according to claim 1, wherein the reaction temperature is from about -25.degree.
