STUDY OF PALLADIUM CATALYST IN THE PROCESS OF ACETYLENE HYDROGENATION IN THE ETHANE-ETHYLENE FRACTION

To purify the ethane-ethylene fraction from acetylene impurities, it is subjected to catalytic hydrogenation. The process of purification of the ethane-ethylene fraction (EEF) of pyrogas from the admixture of acetylenic hydrocarbons is based on the reaction of catalytic hydrogenation of alkynes. The hydrogenation reaction proceeds in the presence of metal or oxide catalysts. To study the kinetics of acetylene hydrogenation, a contact containing 0.04 wt % palladium on α-alumina with a specific surface area of 9 m²/g was used as a catalyst. Tests of the finished catalyst were carried out at temperatures of 40 - 60 ⁰C, a pressure of 2.3-2.5 MPa and a molar ratio of hydrogen and acetylene 1.6-1.9. The selectivity of acetylenic hydrogenation on this catalyst was 90%.
