Abstract:
A process for improving the dispersion of asphaltenes contained in heavy fuel oil, comprising incorporating in said asphaltene containing heavy fuel oil, from 2 to 2000 parts per million parts of said oil of a) and b) whereina) is at least one amine compound of the formula (I) below â€ƒin which n is 1, 2, 3, or 4, A is a radical selected from the group consisting of the formulae (II) to (V) â€ƒwhere R is a C6 to C22 alkyl, and m is 2, 3, or 4, X is a number from 5 to 120, R1 is H, CH3 or H and CH3, where the oxyalkylene radicals are arranged randomly or in blocks, and b) is an oil-soluble or oil-dispersible neutral or basic metal salt compound containing a metal selected from the group consisting of an alkali metal, an alkaline earth metal, copper, silver, zinc, cadmium, titanium, zirconium, molybdenum, chromium, tungsten, iron, cobalt, nickel, lanthan, cerium, and ytterbium, and an organic acid component selected from the group consisting of a carboxylic acid, sulfonic acid, add ester of phosphoric acid, and acid ester of sulfuric acid, each said add and ester containing a hydrocarbon radical of 8 to 40 carbon atoms as the acid component and emulsifying and/or dispersing said asphaltenes in said heavy fuel oil.
