Abstract
The paper describes the hydrogenating thermo-catalytic processing of plastic waste on the developed new catalysts based on natural zeolite from the Tayzuzgen deposit (Kazakhstan), with molybdenum additives (on the base of (NH 4 ) 6 Mо 2 O 24 •4H 2 O).Fuel oil from the Kumkol oil field (Kazakhstan), characterized by a high content of paraffin hydrocarbons, high pour point and low sulfur content was used as additional raw material, source of hydrogen and a paste generator.Analysis of the reaction products shows that the process proceeds mainly with the formation of aromatic compounds, alkanes, cycloalkanes, alkenes and cycloalkenes, isoalkanes.According to the composition of hydrocarbon fractions with a boiling point of up to 180°С on a catalyst with 0.5% Mo, the content of saturated hydrocarbons was relatively high (20.92%),for catalysts containing 1.0% Mo, there was a high content of aromatic hydrocarbons (21% and 45%).The highest yield of the gasoline and diesel fractions is observed at a concentration of Mo (VI) -0.5%.The total yield of liquid distillate obtained by thermal catalytic hydrogenation processing of plastic waste amounted to 34.59% wt.The optimal conditions for the process of hydrogenation of thermal catalytic processing of polymer waste into motor fuels were determined.The synthesized catalysts showed their activity and selectivity and can be used in the process of hydrogenation of thermal catalytic processing of polymer waste into motor fuels.
