Abstract

The invention is in the field of catalysis. More specifically, the invention pertains to catalytic hydrogenation processes and catalysts used therein. According to the invention there is provided a process for the hydrogenation of hydrocarbon resins, in particular hydrocarbon resin feeds with a relatively high sulfur content using a cobalt promoted nickel on silica/alumina catalyst, the catalyst per se, and the process of preparing said catalyst.

First claim

1 . A process for hydrogenation of a hydrocarbon resin feed containing one or more sulfur compounds, the process comprising:
contacting said hydrocarbon resin feed with hydrogen in the presence of a catalyst, wherein said catalyst is a cobalt promoted supported nickel on silica and alumina catalyst, said cobalt promoted catalyst having
a nickel content, calculated as Ni of 45 to 85 wt. %;
a silicon content, calculated as SiO 2 , of 13.75-45 wt. %; and
an aluminum content, calculated as Al 2 O 3 , of 1-15 wt. %,
based on the weight of the reduced catalyst.

2 . The process according to claim 1 , wherein said catalyst has a cobalt content, calculated as Co, of 0.25-12 wt. %, based on the weight of the reduced catalyst.

3 . The process according to claim 1 , wherein said catalyst has a pore volume between 2 and 60 nm of at least 0.35 ml/g of catalyst.

4 . The process according to claim 1 , wherein the one or more sulfur compound content of the hydrocarbon resin is more than 40 ppm, calculated as sulfur, based on the weight of the hydrocarbon resin feed.

5 . A cobalt promoted supported nickel on silica and alumina catalyst, wherein said catalyst comprises:
a nickel content, calculated as Ni of 45 to 85 wt. %; a silicon content, calculated as SiO 2 , of 13.75-45 wt. %; an aluminum content, calculated as Al 2 O 3 , of 1-15 wt. %; and a cobalt content, calculated as Co, of 0.25-1.5 wt. %,
based on the weight of the reduced catalyst.

6 . The catalyst according to claim 5 , wherein the catalyst has a pore volume between 2 and 60 nm of at least 0.35 ml/g of catalyst.

7 . A process for preparing a cobalt promoted supported nickel on silica and alumina catalyst, said process comprises:
coprecipitating one or more nickel salts, cobalt salts, aluminum salts and one or more silicon compounds at a pH-value of 7.0-9.0, recovering the coprecipitated material from the precipitation liquid, washing the recovered copercipitated material; and treating the washed recovered copercipitated material to produce said catalyst, wherein said catalyst comprises:
a nickel content, calculated as Ni of 45 to 85 wt. %;
a silicon content, calculated as SiO 2 , of 13.75-45 wt. %;
an aluminum content, calculated as Al 2 O 3 , of 1-15 wt. %;
a cobalt content, calculated as Co, of 0.25-4 wt. %
based on the weight of the reduced catalyst.

8 . The process according to claim 7 , wherein said catalyst has a cobalt content, calculated as Co, of 0.25-1.5 wt. %, based on the weight of the reduced catalyst.

9 . The process according to claims 7 , wherein said catalyst has a pore volume between 2 and 60 nm of at least 0.35 ml/g of catalyst.

10 . (canceled)

11 . The process according to claim 3 , wherein said catalyst has a pore volume between 10 and 60 nm of at least 0.20 ml/g of catalyst.

12 . The process according to claim 4 , wherein the one or more sulfur compound content of the hydrocarbon resin is more than 100 ppm, calculated as sulfur, based on the weight of the hydrocarbon resin feed.

13 . The catalyst according to claim 6 , wherein the catalyst has a pore volume preferably between 10 and 60 nm of at least 0.20 ml/g of the catalyst.

14 . The process according claims 9 , wherein said catalyst has a pore volume between 10 and 60 nm of at least 0.20 ml/g of catalyst.
