Poster summary

In this work, a series of 1 wt.% Pd/MgO catalysts was synthesized. Such methods as aerogel preparation, xerogel preparation, and incipient wetness impregnation were used. It was shown that the preparation route affects texture and dispersion of the active metal. The Pd/MgO catalysts were investigated in the process of acetylene hydrogenation to ethylene (4% C2H2 + 96% H2; 20 – 90 °C). It was found that the aerogel method is promising for the synthesis of Pd/MgO catalyst for selective hydrogenation of acetylene to ethylene.
