Research Highlights The hydrogenation activity of nickel supported on SBA-15 catalysts, which are prepared by pretreatment with ammonia/water vapour, is improved approximated 100%. The formation of NH 4 NO 3 during pretreatment, which helped to reduce NO 2 /O 2 generation thus enhancing the dispersion of NiO, was considered to be the main reason for the increased Ni 0 dispersion and the ...

The impure metal is reacted with pure carbon monoxide at 50° and the carbonyl produced fractionated several times prior to pyrolysis at around 200°. The nickel thus obtained has a purity of 99.90-99.99% depending upon the materials used. Electrolytic methods for producing high purity nickel depend upon the production of high purity nickel salts.

Catalysts. Most metals catalyse HDS, but it is those at the middle of the transition metal series that are most active. Although not practical, ruthenium disulfide appears to be the single most active catalyst, but binary combinations of cobalt and molybdenum are also highly active.

The Reduction Catalyst The reduction catalyst is the first stage of the catalytic converter. It uses platinum and rhodium to help reduce the NOx emissions. When an NO or NO2 molecule contacts the catalyst, the catalyst rips the nitrogen atom out of the molecule and holds on to it, freeing the oxygen in the form of O2.
