    ABSTRACT: The most important concerns of the petroleum refining Industry in the near future are: meeting the growing market of cleaner fuels, gradual substitution of scarce light low -sulfur refinery feeds by heavy high -sulfur ones, and the decreasing demand for heavy fuel oil .One solution of the above problems is using residue upgrading processes. Furthermore, economic and strategic reasons promote the exploitation of refining residua and also considerable reserves of very heavy crude oils. Accordingly, the selection of proper processes is an important challenge of the petroleum refiners. The present article – considering the aforementioned problems – discusses the most appropriate ones.

    ABSTRACT: We report an experimental investigation of secondary reactions of intermediates in delayed coking. Thermal cracking reactions of intermediates, for example coker naphtha (C5 ~180 °C), light coker gas oil (LCGO, 180–350 °C), middle coker gas oil (MCGO, 350–440 °C), and heavy coker gas oil (HCGO, >440 °C), were investigated. The results reveal that cracking of coker naphtha and LCGO is low under these experimental conditions. Thermal cracking MCGO exceeds that of LCGO. Among all the intermediates, thermal cracking is greatest for HCGO. The secondary reactions of HCGO produce not only gas and liquid products, but also coke. This increase in the yields of gas and coke is attributed to secondary reactions of HCGO and MCGO. Inhibition of the secondary reactions of intermediates results in a greater yield of liquid.
