Abstract
The invention is directed to a process for the production of cyclohexane by catalytic hydrogenation of benzene using hydrogen, said process comprising the hydrogenation of benzene in the presence of a supported nickel catalyst having a nickel content of at least 10 wt. %, calculated as nickel, said catalyst containing sulfur, or compounds thereof, as promotor.
Claims9
A process for the production of cyclohexane, said process comprising the hydrogenation of benzene in the presence of a catalyst consisting essentially of nickel and sulfur or compounds thereof, said catalyst having a nickel content of at least 10 wt. % calculated as nickel.
A process for the production of cyclohexane consisting of the catalytic hydrogenation of benzene with a catalyst consisting essentially of nickel and sulfur or compounds thereof, said catalyst having a nickel content of at least 10 wt. % calculated as nickel said process comprising:
- a) a pressure of between 3 and 150 bar;
- b) a temperature of between 100.degree. C. and 350.degree. C.;
- c) a liquid or gas phase;
- d) utilizing catalyst particles in the shape of granules, pellets or extrudates in the size range from 1/100 inch to 1/2 inch;
- and
- e) recovering the cyclohexane so produced.
