1. A process in which olefinic and carbocyclic petroleum products are converted to high-octane branched-chain alkanes in the presence of hydrogen and a catalyst under pressure and heat.
2. A manufacturing technique in which high-pressure hydraulic fluid is used to mold a sheet or tube of metal stock by forcing it against the surface of a die.

hy′dro·form′er n.


1. (Chemistry) the catalytic reforming of petroleum to increase the proportion of aromatic and branched-chain hydrocarbons
2. (General Engineering) engineering a forming process in which a metal component is shaped by a metal punch forced against a die, consisting of a flexible bag containing a fluid
