Abstract:The fraction compositions, group compositions and structure compositions of seven catalytic stocks were determined by means of vacuum distillation, mass spectrum, element analysis and molecular mass measurement. The effects of the compositions of different catalytic stocks on catalytic cracking reactions were discussed. It is shown that tae gum and asphaltene in the seven catalytic stocks were not very high except residual oil; The saturated hydrocarbon in the seven were all higher; Aromatic contents were lowe… Show more
scite is a Brooklyn-based startup that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
