A surfactant is obtained by treating a mixture of 20 to 95 wt. % of a thermal cracking oil fraction obtained by thermally cracking a petroleum heavy residual oil at 400°to 700°C., for example, by delayed coking and 80 to 5 wt. % of other aromatic source, for example, an aromatic fraction having a co

A surfactant is obtained by treating a mixture of 20 to 95 wt. % of a thermal cracking oil fraction obtained by thermally cracking a petroleum heavy residual oil at 400°to 700°C., for example, by delayed coking and 80 to 5 wt. % of other aromatic source, for example, an aromatic fraction having a comparatively high boiling point with an acid catalyst, and sulfonating and neutralizing the product. This surfactant is used as a dispersing agent for a coal-oil mixture (COM).

A water soluble surface active agent obtained by sulfonating a reaction product boiling higher than hydrocarbons contained in a mixture and not lower than 260°C., under sulfonating conditions, followed by neutralization, which reaction product is obtained by treating said mixture in liquid phase in the presence of an acid catalyst at a reaction temperature of 0°to 330°C. to alkylate aromatics with aliphatic olefins followed by distillation, said mixture consisting of: (A) 20-95 weight percent of a thermal-cracked oil distillate obtained from a delayed coking process for coking a petrolic heavy residual oil at a temperature not lower than 400°C. and not exceeding 700°C., said distillate containing aliphatic olefins; and, either (B) 80-5 weight percent of one or more members boiling in the range of 150°to 250°C. and selected from the following (a) through (c): (a) a thermal-cracked by-product oil distillate obtained by thermal cracking of a petrolic light oil at a temperature of 750°to 850°C. followed by treatment for reducing the content of unsaturated compounds; (b) an reformate distillate obtained by catalytic reforming of a petrolic light oil boiling in the range of 50°to 250°C., followed by treatment for reducing the content of unsaturated compounds if necessary; and (c) an aromatic distillate consisting mainly of aromatic hydrocarbons and obtained by separation from said thermal-cracked by-product oil distillate (a) and/or said reformate distillate (b); or (C) 80-5 weight percent of aromatic hydrocarbons having a boiling range lower than 150°C. and not having an aliphatic double bond.
