Patent ID: 8664459

Claim:
A process for hydrogenating olefins, said process comprising: introducing a feed gas comprising an olefin having one point of unsaturation at a concentration greater than 6 mole %, H2, and at least one sulfur compound through an inlet of a reactor vessel at an inlet temperature from 100° C. to 250° C., said reactor vessel containing a bed of a sulfided metal catalyst said catalyst comprising from 2 wt % to 20 wt % NiO and from 9wt % to 40 wt % MoO 3 on an unsulfided basis supported on an alumina support; contacting said olefin having one point of unsaturation and said H 2 with said catalyst to react said olefin having one point of unsaturation and said H 2 under reaction conditions effective to hydrogenate said olefin having one point of unsaturation to produce a saturated hydrocarbon; and withdrawing an outlet gas mixture comprising said saturated hydrocarbon from said reactor vessel through an outlet at an outlet temperature from 120° C. to 425° C., wherein said reactor is operated adiabatically.
