Benefits of technology

[0008] The current invention includes a catalyst for and a process for hydrotreating/hydrocracking heavy hydrocarbons. The catalyst is particularly useful for treating de-metallized oil (DMO) and is particularly useful in VGO/DMO hydrocarbon blend. The catalyst acts to catalytically convert the VGO/DMO blend to shorter-chain valuable hydrocarbon products. The catalyst includ

Problems solved by technology

ASA has a non-uniform structure with low acidity and high surface area.
The non-uniform structure tends to create acidic sites that are not available to large molecules, which leads to inferior performance of ASA alone as compared to MCM-41 or a combination of MCM-41 with ASA.
Similarly, the USY and β-zeolite supports suffer from drawbacks related to the microporous nature of th

Embodiment Construction

[0020] Several catalysts were prepared using nickel (Ni) / molybdenum (Mo) metals loadings along with the four different support materials identified above. The four catalyst formulations created in this manner were characterized using gas sorption analyzer, temperature programmed reduction (TPR) and temperature programmed de-sorption (TPD). Moreover, the catalyst formulations were tested in a batch reactor and compared against a commercial catalyst. The outcome of this work showed that the formulation including MCM-41 catalyst support, resulting in NiMo-MCM-41, has performed better than the commercial catalyst on heavy hydrocarbons, in particular, VGO / DMO blends. NiMo-MCM-41 showed higher hydrodesulfurization (HDS) and hydrogenation activities. In addition, it had higher conversion and higher diesel yield than commercial catalyst.

[0021] Most of the hydrocracking catalysts of commercial interest are dual functional in nature, consisting of both a hydrogenation-dehydrogenation compone...

Abstract

This invention relates to a catalyst and a process for treating heavy hydrocarbons using the catalyst. The catalyst is useful for treating heavy hydrocarbons, de-metallize oil (DMO) and is particularly useful in VGO/DMO hydrocarbon blend. It is also useful for DAO. The catalyst acts to catalytically convert the VGO/DMO blend to shorter-chain valuable hydrocarbon products. The catalyst includes a catalytic support material, a catalytic metal impregnated upon the catalytic support material, and a promoter metal on the catalytic support material to enhance catalytic conversion. The combination of the catalytic support material with catalytic metal and promoter metal is operable to catalytically convert VGO/DMO into hydrocarbon products having shorter carbon chains.

Description

RELATED APPLICATIONS [0001] This patent application claims priority to U.S. Provisional Patent Application Ser. No. 60 / 639,909 filed on Dec. 29, 2004, which is incorporated by reference in its entirety.BACKGROUND OF THE INVENTION [0002] 1. Technical Field of the Invention [0003] This invention relates generally to the field of catalytic treatment of heavy hydrocarbons to produce desirable hydrocarbon products, in particular, a novel catalyst operable to catalytically treat de-metallized oil (DMO) and Vacuum Gas Oil (VGO) Blend. [0004] 2. Description of the Prior Art [0005] The flexibility of hydrocracking as a process for refining petroleum has resulted in its phenomenal growth during the past 15 years. Through catalytic treatment, feedstocks can be converted to lower boiling or more desirable products. Hydrocarbon feedstocks suitable for such treatment range from residue to naphtha. Products include such widely diverse materials such as gasoline, kerosene, middle distillates, lubri...
