摘要
The effect of the rare earth elements (REEs) content in range from 0 to 3 wt.% in the cracking catalyst on n-undecane and cumene transformations in the presence of heterocyclic sulfur and nitrogen compounds was studied. The catalyst samples acidity increased at raising the REEs content in the catalysts up to 2 wt.%. The catalyst acidity was sharply reduced with a further increase in the REEs. This phenomenon led to an enhanced conversion of the feed and a decreased formation of highly poisonous nitrogen compounds. The relative conversions of n-undecane and cumene in the presence of nitrogen and sulfur compounds were 95 and 97 rel.%, accordingly.
