Abstract:H2S evolution during different oil shale samples pyrolysis was studied in fixed bed in the nitrogen atmosphere. The results show the H2S evolution is influenced by pyrolysis conditions and properties of oil shale. The yield of H2S released for two samples had a marked change at 300-600℃ of final temperature and 5-50℃/min of heating rate. Both the H2S yields of two samples increase with grain size increasing. While the H2S yields of Huadian oil shale was far more than that of Wangqing under same pyrolysis condi… Show more
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.
