Crude residua can be thermally cracked to more valuable products by using a reaction diluent such as Tetralin, which gives up hydrogen to cracked residua. The Tetralin is dehydrogenated to naphthalene, and the residua are converted into lower boiling products with little coke and dry gas.
tribution quotients for strontium. Dsr, and barium, DBa, were calculated for stages throughout the extractor. I n the scrub section, Ds, had values in the range of 0.7 to 1.1. while DBs had values, except for stage 3, in the range of 0.2 to 0.3.The separation factors, p values, for the scrub section were in
scite is a Brooklyn-based organization 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 and 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.
