Abstract:
The effect of adding clay with different contents of iron oxides to a catalytic cracking system on the distribution of feedstock sulfur in synthesized products and the amount of sulfur oxides formed during the regeneration of coked catalyst after the cracking of a model sulfur-containing feedstock with a sulfur content of 10000 ppm, derived from 2-methylthiophene or benzothiophene has been studied. The fraction of the feedstock sulfur converted into liquid products and coke can be seen to grow when a sulfur-containing component with a higher molecular weight is used. Raising the content of iron oxide in the catalyst from 0.61 to 1.53 wt % increases the yield of liquid products during the cracking of a model feedstock, reduces the conversion of a model hydrocarbon. The yield of coke on the catalyst grows from 3.8 to 5.2 wt %, and the fraction of feedstock sulfur converted into SO2 quadruples.
