ˌhydrodeˌsulphuriˈzation
Also (U.S.) -sulfur-.
[f. hydro- + de- II. 1 + sulphur + -ization.]
The removal (as hydrogen sulphide) of sulphur from crude petroleum or a petroleum product by the action of a catalyst and gaseous hydrogen at a moderately high temperature and pressure.
1950Industr. & Engin. Chem. Sept. 1882/2 Several high sulfur gas oils were reduced in sulfur contents to those of gas oils from sweet crudes by hydrodesulfurization..at 750°F., 300 pounds per square inch pressure,..and 1000 cubic feet of hydrogen per barrel of charge. 1967Proc. 7th World Petroleum Congr. IV. 167/2 Hydrodesulphurization has long been recognized as a means of removing sulfur [from] residual oils and asphalts.
Hence (as a back-formation) ˌhydrodeˈsulphurize v. trans., to subject to hydrodesulphurization; ˌhydrodeˈsulphurized ppl. a., -deˈsulphurizing vbl. n. Also ˌhydrodeˈsulphurizer, an apparatus in which this process is carried out.
1950Industr. & Engin. Chem. Sept. 1881/1 Instead of processing the gas oil, it is possible to hydrodesulfurize the entire crude. 1955Industr. Chemist XXXI. 351/1 The first commercial hydrodesulphurizer applying the Shell trickle technique was recently started up. 1960Times Rev. Industry Jan. 31/1 The regeneration of hydrodesulphurising catalysts for further use. 1967Proc. 7th World Petroleum Congr. IV. 168/2 The hydrodesulfurized product tends to be relatively rich in nickel. |
