A recently granted patent (Publication Number: US11766666B2) discloses a catalyst for converting alkene or alkane into aromatics. The catalyst comprises a zeotype material, a binder, and a metal phosphide. The zeotype material is a microporous substance, which can be selected from various options including alumino-silicate zeolite, alumino-phosphate molecular sieve, silico-alumino-phosphate molecular sieve, metallo-alumino-phosphate molecular sieve, or a combination thereof. The zeotype material can have a framework selected from MFI, MTW, MEL, TON, TUN, IMF, BEA, FAU, MOR, AEI, CHA, AFI, MWW, MTT, LTL, FER, EMT, or a combination thereof.

The binder material, which can be present in the catalyst in a range of 0 to 50% by weight, is selected from options such as silica, alumina, alumina-silica, zirconia, titania, aluminum phosphate, or a combination thereof. In this particular embodiment, the binder material is alumina. The metal phosphide, which is present in a range of 0.01% to 10% by weight, comprises a phosphide of nickel (Ni). However, the metal phosphide can also include phosphides of other metals such as cobalt (Co), gallium (Ga), iron (Fe), zinc (Zn), copper (Cu), manganese (Mn), indium (In), tin (Sn), molybdenum (Mo), or a combination thereof. The metal phosphide has an atomic ratio of metal to phosphorus in a range of 3:1 to 0.5:1.

The catalyst is configured to convert olefin-containing hydrocarbons, specifically those containing at least one alkene, into aromatic hydrocarbons such as benzene, toluene, xylenes, or a combination thereof. The alkene can be selected from options including ethylene, propylene, butylene, or a combination thereof. The zeotype material, particularly ZSM-5 zeolite, is characterized by a silica to alumina ratio (SAR) in the range of 20 to 100.

This patented catalyst offers a promising solution for the conversion of alkene or alkane into valuable aromatic hydrocarbons. By utilizing a combination of zeotype material, binder, and metal phosphide, the catalyst demonstrates potential for efficient and selective conversion of olefin-containing hydrocarbons into desired aromatic compounds. The specific composition and ratios of the catalyst components provide flexibility and control over the conversion process. Further research and development based on this patent could lead to advancements in the field of hydrocarbon conversion and the production of valuable aromatic compounds.
