hydroformingn.

/ˈhʌɪdrəʊfɔːmɪŋ/

Etymology: < hydro- comb. form + -forming, after reforming n.¹

In the petroleum industry, a catalytic reforming process that converts the paraffins and alicyclic compounds in low-octane petroleum naphtha to aromatic compounds by dehydrogenation at a high temperature and moderate pressure in the presence of gaseous hydrogen. Frequently attributive.

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.
