Abstract
Abstract Catalysts having a substantially spherical shape, a void center and a hole in the external surface communicating to the void center, have been found to give superior results in known hydrotreating reactions where sulfur, nitrogen and/or oxygen is removed from a hydrocarbon feed stock.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
85 words
In the process of hydrotreating a hydrocarbon feed stock containing compounds with carbon-sulfur bonds, carbon-nitrogen bonds and carbon-oxygen bonds by contacting the hydrocarbon feed stock with hydrogen at an elevated temperature and with a hydrotreating catalyst to remove sulfur, nitrogen and oxygen from the hydrocarbon feed stock, the improvement comprising, using as at least part of said catalyst an amphora catalyst having a substantially spherical shape, a void center therein and an opening on the external surface of said catalyst communicating with said void center.
Claim 2
Dependent Claim
85 words
In the process of hydrotreating a hydrocarbon feed stock containing compounds with carbon-sulfur bonds, carbon-nitrogen bonds and carbon-oxygen bonds by contacting the hydrocarbon feed stock with hydrogen at an elevated temperature and with a hydrotreating catalyst to remove sulfur, nitrogen and oxygen from the hydrocarbon feed stock, the improvement comprising, using as at least part of said catalyst an amphora catalyst having a substantially spherical shape, a void center therein and an opening on the external surface of said catalyst communicating with said void center.
Claim 3
Dependent Claim
14 words
The process of claim 1 wherein the amphora catalyst is an alumina based catalyst.
Claim 4
Dependent Claim
32 words
The process of claim 1 wherein the amphora catalyst contains at leastt one compound of the elements selected from the group consisting of Group VIB and Group VIII of the Periodic Table.
Claim 5
Dependent Claim
9 words
The process of claim 1 wherein sulfur is removed.
Claim 6
Dependent Claim
9 words
The process of claim 1 wherein nitrogen is removed.
Claim 7
Dependent Claim
9 words
The process of claim 1 wherein oxygen is removed.
Claim 8
Dependent Claim
22 words
The process of claim 1 wherein the catalyst employed in said contacting comprises at least 20% by weight of said amphora catalyst.
Claim 9
Dependent Claim
22 words
The process of claim 1 wherein the catalyst employed in said contacting comprises at least 50% by weight of said amphora catalyst.
Claim 10
Dependent Claim
18 words
The process of claim 1 wherein substantially all of said catalyst in said contacting comprises said amphora catalyst.
