hydrofiningn.

/ˈhʌɪdrəʊfʌɪnɪŋ/

Etymology: < hydro- comb. form + -fining (in refining 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.

1931 C. 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.
