The present invention pertains to a process for the hydroprocessing of heavy hydrocarbon feeds, preferably in an ebullating bed process, by contacting the feed with a mixture of two hydroprocessing catalysts meeting specified pore size distribution requirements. The process combines high contaminant removal with high conversion, low sediment formation, and high process flexibility.

Heavy feed HPC process using a mixture of catalysts

The present invention pertains to a process for hydroprocessing a heavy hydrocarbon oil, comprising contacting a heavy hydrocarbon oil in the presence of hydrogen with a mixture of hydroprocessing catalyst I and hydroprocessing catalyst II. The process of the invention combines high contaminant removal with high conversion, low sediment formation, and high process flexibility.

HPC process using a mixture of catalysts

The present invention pertains to a method for hydroprocessing a heavy hydrocarbon oil, comprising bringing a heavy hydrocarbon oil into contact with hydroprocessing catalyst I in the presence of hydrogen in a first stage, after which the effluent of the first stage is contacted in whole or in part with hydroprocessing catalyst II in the presence of hydrogen in a second stage. The method according to the invention combines efficient contaminant removal with high cracking rate and low sediment formation. The invention also pertains to the combination of catalysts.

Two-stage heavy feed hpc process

The present invention pertains to a catalyst comprising 7&#x2013;20 wt. % of a Group VIB metal component, calculated as trioxide on the weight of the catalyst, and 0.5 to 6 wt. % of a Group VIII metal component, calculated as oxide on the weight of the catalyst, on a porous inorganic carrier. The catalyst has a specific surface area of 100&#x2013;180 m/g, a total pore volume of at least 0.55 ml/g, at least 50% of the total pore volume in pores with a diameter of at least 20 nm (200 &#x212b;), 10&#x2013;30% of the total pore volume in pores with a diameter of at least 200 nm (2000 &#x212b;), and 0&#x2013;1% of the total pore volume in pores with a diameter above 1000 nm (10000 &#x212b;). The catalyst is particularly suitable for the hydroprocessing of heavy hydrocarbon feeds of which at least 50 wt. % boils above 538&#xb0; C. (1000&#xb0; F.). It is especially advantageous for the hydroprocessing of feedstocks of which at least 80 wt. % boils above 538&#xb0; C. (1000&#xb0; F.).

High-macropore hydroprocessing catalyst and its use

The invention pertains to a hydroprocessing catalyst suitable for the conversion of heavy hydrocarbon oils, which comprises 7&#x2013;20 wt. % of Group VI metal, calculated as trioxide, and about 0.5&#x2013;6 wt. % of Group VIII metal, calculated as oxide, on a carrier comprising alumina, the catalyst having a surface area of about 100&#x2013;180 m/g, a total pore volume of about 0.55 ml/g or more, a % PV(&#x3e;200 &#x212b; d) of at least about 50%, a % PV(&#x3e;1,000 &#x212b; d) of at least about 5%, a % PV(100&#x2013;1,200 &#x212b; d) of at least about 85%, a % PV(&#x3e;4,000 &#x212b; d) of about 0&#x2013;2%, and a % PV(&#x3e;10,000 &#x212b; d) of about 0&#x2013;1%. The catalyst of the present invention shows improved metals and asphaltene removal, combined with appropriate sulfur, nitrogen, and Conradson carbon removal. Additionally, the catalyst shows a decrease in sediment formation and an improved conversion in ebullating bed operations. In fixed bed operation, the catalyst produces product with an improved storage stability. The invention also pertains to a process for hydroprocessing heavy hydrocarbon feeds with the catalyst according to the invention in fixed bed or ebullating bed operation.
