Presented is a selective hydrogenation catalyst and a method of making the catalyst. The catalyst comprises a carrier containing bi-metallic nanoparticles. The nanoparticles comprise a silver component and a palladium component. The catalyst is made by incorporating an aqueous dispersion of the bi-metallic nanoparticles onto a catalyst carrier followed by drying and calcining the carrier having incorporated therein the dispersion. The catalyst is used in the selective hydrogenation of highly unsaturated hydrocarbons contained olefin product streams.

Processes to selectively crack alkyne compounds from a hydrocarbon stream including olefinic and di-olefinic compounds are described. The process includes contacting the hydrocarbon stream with a supported CuO catalyst under conditions sufficient to crack the alkynes to form a product stream that included cracked compounds and further separating the cracked organic compounds from the hydrocarbon stream.

Provided is a technology to convert an oil having a high content of Cl into a solvent. Impurities such as Cl, S, N, and metals are removed from an oil having a boiling point of 340 C. or lower in a waste oil having a high content of Cl, and hydrogenation is carried out to recover an oil, and the oil may be applied as a solvent. Separation by boiling points to meet the properties of the solvent product is performed, a solid acid material and an oil having a high Cl content are mixed, impurities are removed by a heat treatment at a high temperature, and hydrogenation is carried out with a metal oxide catalyst, thereby manufacturing a solvent product.
