Abstract
Abstract This invention relates to a catalyst for hydrotreatment of hydrocarbons comprising one or more of metals selected from the group consisting of transition metals and metals of group IIb of the periodic table supported on sepiolite. More particularly it relates to a catalyst effective in the selective demetallization treatment of hydrocarbons.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
74 words
A method for hydrotreating to dometalize hydrocarbons with pressurized hydrogen at a pressure of from about 10 to about 350 kg/cm 2 and at a temperature of from about 300° to about 500° C. in the presence of a catalyst comprising sepiolite having supported thereon at least one catalytic metallic component of at least one metal selected from the group consisting of metals of group IIb and the transition metals of the periodic table.
Claim 2
Independent Claim
74 words
A method for hydrotreating to dometalize hydrocarbons with pressurized hydrogen at a pressure of from about 10 to about 350 kg/cm 2 and at a temperature of from about 300° to about 500° C. in the presence of a catalyst comprising sepiolite having supported thereon at least one catalytic metallic component of at least one metal selected from the group consisting of metals of group IIb and the transition metals of the periodic table.
Claim 3
Dependent Claim
28 words
