(US20150329444) Processes for the disproportionation and isomerization of a C5 hydrocarbon feed using a liquid catalyst comprising an ionic liquid and a carbocation promoter are described. The ionic liquid is unsupported, and the reactions occur at temperatures below about 200° C.
(US9181150) 1. A hydrocarbon conversion process comprising: disproportionating a hydrocarbon feed comprising C5 alkanes by contacting the hydrocarbon feed with a liquid catalyst in a reaction zone under disproportionation conditions to form a product mixture comprising at least about 5 wt % C4- alkanes, and at least about 5 wt % C6+ alkanes in 30 min based on the C5 alkanes in the hydrocarbon feed, wherein the liquid catalyst comprises an unsupported ionic liquid and a carbocation promoter, and wherein a mass ratio of the liquid catalyst to the hydrocarbon feed is less than 0.75:1; wherein the ionic liquid comprises an organic cation where R1-R4 are independently selected from C1-C20 hydrocarbons, C1-C20 hydrocarbon derivatives, halogens, and H; wherein the ionic liquid comprises an anion selected from the group consisting of AlCl4-, Al2Cl7-, Al3Cl10-, AlCl3Br-, Al2Cl6Br-, Al3Cl9Br-, AlBr4-, Al2Br7-, Al3Br10-, GaCl4-, Ga2Cl7-, Ga3Cl10-, GaCl3Br-, Ga2Cl6Br-, Ga3Cl9Br-, CuCl2-, Cu2Cl3-, Cu3Cl4-, ZnCl3-, FeCl3-, FeCl4-, Fe3Cl7-, PF6-, and BF4-; and wherein the carbocation promoter comprises 2-chloro-2-methylpropane, 2-chloropropane, 2-chlorobutane, 2-chloro-2-methylbutane, 2-chloropentane, 1-chlorohexane, 3-chloro-3-methyl pentane, or combinations thereof.
