Abstract

1307542 Reducing coke formation in tubular cracking ESSO RESEARCH & ENG CO 21 May 1970 24628/70 Heading C5E In the production of unsaturated hydrocarbons, e.g. ethylene and butadiene, by thermal cracking of a hydrocarbon feed in the presence of steam in a tubular furnace, coke formation is reduced by providing a phosphorus compound and/or a bismuth compound in the vapour phase in the cracking zone. Suitable compounds are listed, and may be added continuously or intermittently or even as a pretreatment of the tubes since they have been found to exhibit a lasting effect. Coke reduction is obtained even with highsulphur feeds. In examples the feed is ethane or high-sulphur ethane, and the P or Bi is added in the form of H 3 PO 4 , trimethyl phosphate, PH 3 or Bi 2 O 3 .
