“…Catalysts based on Sibunit have been successfully used earlier in the processes of selective hydrogenation [24][25][26]. We have also previously shown that bimetallic Pd-Ga [4,27], Pd-Ag [28,29], and Pd-Zn [30,31] catalysts supported on Sibunit (C) exhibit high selectivity in the reaction of acetylene hydrogenation to ethylene, both in the liquid and gas phases.…”

“…Ethylene is a key industrial chemical mainly derived from thermal cracking of hydrocarbons. The cracked gas usually contains traces of acetylene which can deactivate the catalyst for downstream ethylene polymerization. At the same time, acetylene will also cause quality degradation of polyethylene . Selective hydrogenation is the most economical and convenient way to handle the acetylene impurity in cracked gas, and has always attracted the attention of many researchers. , Meanwhile, acetylene hydrogenation is still a study of great potential application value in producing ethylene in countries where oil is scarce but rich in coal resources. , It can alleviate the dependence of these countries on crude oil to a large extent. In the process of acetylene semihydrogenation, preventing the intermediate product ethylene from being further hydrogenated to ethane has always been the crucial topic.…”

“…Supported bimetallic catalysts based on palladium are widely used for practically important hydrocarbon conversion reactions such as hydrogenation, dehydrogenation, methanol steam reforming, oxidation processes, hydrodeoxygenation etc. [1][2][3][4][5][6][7][8] The traditional synthesis scheme of such catalysts includes the deposition of the active component precursors on the support, followed by the stages of drying and heat treatment. Reductive treatment is the most important procedure, since the decomposition of the precursors and their interaction with each other, as well as the formation of the morphology and size of the catalyst particles are occur.…”
