Publisher Summary In steam cracking, research activities have been concentrated increasingly on feedstocks boiling above naphtha, during the last decade. This development was co-initiated [l] and has been accompanied by the Department for Basic Organic Materials of the Central Institute of Organic Chemistry of the G.D.R. Academy of Sciences in Leipzig. The chapter illustrates special problems in olefin production from atmospheric gas oil (AGO) and vacuum gas oil (VGO) via two routes that are steam cracking of products obtained by hydrocatalytical pretreatment of the straight-run fractions and the direct pyrolysis of the straight-run hydrocarbon fractions in the presence of a special catalyst.
