SELECTION OF A BINDER FOR A ZEOLITE-CONTAINING CRACKING CATALYST ON AL-PILLARED TAGAN MONTMORILLONITE

It was shown that the strength of Al(2.5) NaHMM + HLaY + NaMM catalysts increases significantly with the introduction of NaMM. The optimal amount of NaMM additive is 10 mass%. With an increase in the calcination temperature of this catalyst, an increase in strength is observed, which reaches a maximum value (223.4 N/sm(2)) at 600 degrees C. A further increase in the amount of introduced NaMM to 15 and 20 wt.% reduces the strength of the catalysts at all studied calcination temperatures. On Al (2.5) NaHMM + HLaY + NaMM catalyst, a large amount (42.5%) of gaseous hydrocarbons is formed at 500 degrees C, which decreases with an increase in cracking temperature to 550 degrees C. The gasoline yield at 500 degrees C is 42.0%, light gas oil 5.5%. With an increase in cracking temperature, the yield of gasoline decreases to 39.5%, and light gas oil increases to 15.8%. Under these conditions, a decrease in the yield of gaseous hydrocarbons to 28.8% is observed. Comparison of the results of VG cracking on catalysts with and without NaMM binder showed that the introduction of NaMM does not significantly affect the yield of gasoline.
