use of nickel as a catalyst for industrial processes

Nickel-Based Catalyst - an overview ScienceDirect Topics

The industrial process often adopts an adiabatic pre-reforming step where a nickel-based catalyst decomposes complex hydrocarbons according to equation [15.3] to avoid cracking in the actual reformer and feeds it with an uniform stream independently of the composition of the primary fuel. Pre-reformer operating temperature is set according to ...

Nickel Bis(diselenolene) as a Catalyst for Olefin ...

2016-9-28  Abstract. Nickel bis (dithiolene) reversibly binds olefins via a known interligand binding mechanism, but the complex has limited practical use, due to a competitive intraligand addition which results in decomposition. The present work examines an alternative nickel-based complex that eliminates the decomposition route.

5 Important Uses of Nickel Refractory Metals and Alloys

5 Important Uses of Nickel. Nickel is a silver-white metal with element symbol Ni and a relative atomic mass of 58.69. Nickel has a density of 8.9g / cm³, a melting point of 1455 ° C, and a boiling point of 2730 ° C. Because nickel is hard, has good ductility, magnetic and corrosion resistance, and can be highly polished, it has been widely used in industry and our daily lives.
