Abstract
A method of reducing the fouling propensity of a hydrocarbon feed stream having a Total Base Number based on ASTM method D2896-11 of less than 150 ppm and/or a P-value according to ASTM method D7060-09 of less than 1.15 which method comprises processing the feed stream such that the product obtained has a calculated Total Base Number of at least 150 ppm, a calculated P-value of at least 1.15 and a calculated Po-value higher than the FRmax of the feed stream, more specifically blending at least two hydrocarbon feed streams to prepare a blend having these properties.
