hydrofining, vbl. n.|ˈhaɪdrəʊfaɪnɪŋ|
[f. hydro- + refining vbl. n.]
A catalytic process in which a petroleum product is stabilized and its sulphur content reduced by treatment with gaseous hydrogen under relatively mild conditions, so that unsaturated hydro-carbons and sulphur compounds undergo selective hydrogenation.
1931C. Ellis Hydrogenation Org. Subst. xlviii. 578 The term hydrofining is best applied to those treatments by hydrogen which are carried out at temperatures in the lower ranges,..where no extensive alteration of the carbon-containing molecule occurs. On the other hand, where great disturbance of carbon structure results the process is better denominated hydroforming. 1955Petroleum Refiner May 154/1 Hydrofining was found to..improve the burning quality of West Texas No. 1 fuel oil. 1970J. R. Hughes Storage & Handling Petroleum Liquids (ed. 2) 5 Hydrofining and autofining aim to remove or reduce the content of unwanted sulphur compounds.
So ˈhydrofined ppl. a., obtained by hydrofining.
1931C. Ellis Hydrogenation Org. Subst. xlviii. 577 The hydrofined lubricating oils are not as readily oxidized as the untreated oils. 1955Petroleum Refiner May 153/2 The quality of the raw and hydrofined distillates was determined by inspection tests, measurement of hydrogen content, and burning-quality tests. |
