Abstract

1282946 Crude oil and fuel compositions SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ NV 18 Dec 1969 [20 Dec 1968] 61720/69 Headings C5E and C5G The flow properties of wax-containing crude oils and heavy fuel compositions are improved by the addition of 0À001-2 wt. per cent of polysaccharide derivatives having saturated aliphatic hydrocarbon side chains with more than 15 carbon atoms. Suitable polysaccharides are starch paste, dextrins, starch, amylose, amylopectin and cellulose. The side chains are preferably unbranched and contain up to 30 carbon atoms and can be attached to the polysaccharide either directly or via a carbonyl group. Suitable derivatives have molecular weights between 1000 and 1,000,000 and are made by reacting aliphatic acid chlorides, e.g. of stearic acid or of hydrogenated rape oil fatty acids, with the polysaccharide, e.g. amylose or dextrin. Suitable fuels are crude oils, distillates flashed from atmospheric residues, and blends of atmospheric residues of crude oils with hydrocarbon distillates and contain wax of melting point above 35‹ C. and boiling point above 350‹ C.
