摘要：

Catalysts based on mesoporous silica gel doped with cerium, terbium and modified with silver (Ce-Ag/MPS, Tb-Ag/MPS) were obtained by the template method. The physicochemical characteristics of the obtained catalyst were studied by low-temperature nitrogen adsorption-desorption, scanning electron microscopy, X-ray diffraction analysis, inductively coupled plasma mass spectrometry, and IR spectrometry. The possibility of using the obtained samples as effective and selective catalysts for the hydrogenation of 1-hexyne/1-hexene and 1-heptyne/1-heptene hydrocarbon mixtures (with 30% alkyne content) in the temperature range of 130-160 degrees C and a hydrogen pressure of 3 atm was studied. It was found that the Tb-Ag/MPS catalyst is more effective, maintaining alkene selectivity with increasing hydrogenation temperature.
