Mesoporous material with active metals

Abstract

A process for treating organic compounds includes providing a composition which includes a substantially mesoporous structure of silica containing at least 97% by volume of pores having a pore size ranging from about 15 Å to about 30 Å and having a micropore volume of at least about 0.01 cc / g, wherein the mesoporous structure has incorporated therewith at least about 0.02% by weight of at least one catalytically and / or chemically active heteroatom selected from the group consisting of Al, Ti, V, Cr, Zn, Fe, Sn, Mo, Ga, Ni, Co, In, Zr, Mn, Cu, Mg, Pd, Pt and W, and the catalyst has an X-ray diffraction pattern with one peak at 0.3° to about 3.5° at 2θ. The catalyst is contacted with an organic feed under reaction conditions wherein the treating process is selected from alkylation, acylation, oligomerization, selective oxidation, hydrotreating, isomerization, demetalation, catalytic dewaxing, hydroxylation, hydrogenation, ammoximation, isomerization, dehydrogenation, cracking and adsorption.

CROSS-REFERENCE TO RELATED APPLICATIONS [0001] The present application is a continuation in part of U.S. application Ser. No. 09 / 995,227 filed Nov. 27, 2001 and incorporated by reference herein, which is a continuation in part of U.S. application Ser. No. 09 / 390,276 filed Sep. 7, 1999, now issued as U.S. Pat. No. 6,358,486 B1, to which priority is claimed.BACKGROUND [0002] 1. Field of the Invention [0003] The present invention relates to a mesoporous material, particularly a catalytic material, and use of the mesoporous material for the conversion of organic compounds, particularly hydrocarbons. [0004] 2. Background of the Prior Art [0005] Most of today's hydrocarbon processing technologies are based on zeolite catalysts. Zeolite catalysts are well known in the art and possess well-arranged pore systems with uniform pore sizes. However, these materials tend to possess either only micropores or only mesopores. Micropores are defined as pores having a diameter less than about 2 nm. Me...

AI Technical Summary

Benefits of technology

"The patent text describes a process for treating organic compounds by using a catalyst that can reduce high metals, sulfur, nitrogen, and CCR content in petroleum oils. The process involves using a mesoporous structure of silica containing active heteroatoms, such as Al, Ti, V, Cr, Zn, Fe, Sn, Mo, Ga, Ni, Co, In, Zr, Mn, Cu, Pd, Pt, and W. The catalyst has a specific X-ray diffraction pattern with one peak at 0.3 to 3.5° at 2θ. The process can be used for various reactions such as alkylation, acylation, oligomerization, selective oxidation, hydrotreating, isomerization, dehydrogenation, cracking, and adsorption. The high metals, sulfur, nitrogen, and CCR content in residual fractions can limit their effective use in catalyst processing and cause various problems such as premature aging of catalyst, unwanted side reactions, and emissions. The invention provides an efficient method to reduce these contaminants and improve the quality of residual petroleum oils."

Problems solved by technology

Principal metal contaminants are nickel and vanadium, with iron and small amounts of copper also sometimes present.

The high metals, sulfur, nitrogen, and CCR content of the residual fractions generally limit their effective use as charge stocks for subsequent catalyst processing such as catalytic cracking and hydrocracking.

The metal contaminants deposit on the special catalysts for these cracking processes and cause the premature aging of the catalyst and / or unwanted side reactions such as cracking to coke, dry gas and hydrogen.

During the FCC process, much of the sulfur ends up in the FCC catalyst's coke, which is burned during regeneration, resulting in substantial SOx emissions.

Some of the nitrogen contributes to NOx emissions, and some nitrogen (the basic nitrogen compounds) becomes bound to the active sites of the FCC catalyst and renders it ineffective.

CCR, a measure of a molecule's tendency to coke rather than crack and / or distill, is also an undesirable property for charge streams processed by catalytic cracking.
