Abstract
A process for removing suspended solids particularly difficultly filterable inorganic solids from an oil obtained as a refinery process bottom fraction from both steam and catalytic cracking units (e.g. catalytic cracker bottoms) or from coal conversion processes (e.g. coal tar) by adding to the oil an agglomerating agent comprising an oxyalkylated phenol formaldehyde resin glycol ester whereby said solids are clustered together into readily filterable agglomerates.
Claims9
A process for reducing the particulate solids content of a hydrocarbon oil fraction comprising:
- providing a hydrocarbon oil fraction boiling in the range of from about 200.degree. C. to about 550.degree. C.;
- treating said hydrocarbon oil fraction with an agglomeration aid wherein the resulting mixture contains from 10 to 1000 weight parts per million of said aid based on the total weight of said mixture, said agglomeration aid comprising oxyalkylated phenol formaldehyde resin glycol ester of Mw ranging from 500 to 50,000;
- and,
- recovering a hydrocarbon oil bottoms portion having a reduced content of filterable solids.
