Aromatization of Ethane and Propane on Modified Pentasils.

1. Platinum- and zinc-containing catalysts based on pentasil HTsVM have been studied in the aromatization of C2-C3 alkanes. It is shown that modification of the H form of the zeolite by zinc oxide (0.5% Zn) doubles the yield of aromatic hydrocarbons from ethane. For propane, the yield of aromatic hydrocarbons on the most active samples reaches 53%. 2. It is shown that HTsVM successfully aromatizes propane with a yield of up to 37% based on alkane admitted. 3. The contribution of thermal process to the conversion of C2-C3 alkanes in the range 500–700°C has been determined. It amounted to about 10% for propane (500°C) and ethane (600°C).
