The study of catalytic activity of copper nanoparticles in the reaction of hydrogenation of hexyne-1

The process of hydrogenation of unsaturated hydrocarbons is one of the main processes of the petrochemical industry. Unsaturated hydrocarbons are practically inseparable from alkanes, which have the same mass, and to obtain high-quality gasoline unsaturated hydrocarbons are to be eliminated. Furthermore, acetylenic hydrocarbons must be removed from an olefinic feedstock, which is intended for the production of polymers. These problems can be solved by using catalysts with different selectivities. The article studied the copper nanoparticles in the hydrogenation reaction hexyne-1. The nanoparticles were obtained by means of levitation blasting and mixed with inerton. Analysis of the reaction mixture was performed by means of gas chromatography. We calculated the rate constants at different temperatures and measured the activation energy of the reaction. It is shown that the first hexyne-1 is converted to hexene-1, followed by hexane. Thus, the catalyst shows the analyzed selective properties, which enables selection of the conditions for obtaining the priority of a particular product.
