Abstract
The study revealed the effect of a clay with different content of iron oxides introduced into the cracking catalyst composition on the distribution of feedstock sulfur in the products and on the amount of sulfur oxides formed upon regeneration of the coked catalyst after cracking of the model sulfur-containing feedstock with a sulfur content of 10 000 ppm from 2-methylthiophene or benzothiophene. The use of a sulfur compound with a higher molecular weight increased the fraction of the feedstock sulfur passing into liquid products and coke. When iron oxidecontent in the catalyst was increased from 0.61 to 1.53 wt.% upon cracking of the model feedstock, the yield of liquid products increased, the conversion of model hydrocarbon decreased, and the yield of coke on the catalyst grew from 3.8 to 5.2 wt.%; in the process, the fraction of the feedstock sulfur that passed into SO2 increased fourfold.
