Method of making a fluoride functionalized zeolite catalyst and method of use
A method for producing a fluoride functionalized zeolite catalyst is described, having a F/Si molar ratio of 0.1:1-3:1. The method involves mixing a fluoride salt with zeolite components to form a gel, which is then hydrothermally treated and calcined. The fluoride functionalized zeolite catalyst may be used for cracking an olefin stream into ethylene, propylene, and butylene, with high selectivity towards propylene. The fluoride functionalized zeolite catalyst may be used for 50 or more hours with a stable conversion rate and low coke formation.
CATALYSTS AND PROCESSES FOR THE CONVERSION OF SYNTHESIS GAS TO LIQUEFIED PETROLEUM GAS (LPG) HYDROCARBONS
Liquefied petroleum gas (LPG) synthesis catalyst systems are disclosed that provide activities for both alcohol (e.g., methanol) synthesis and in situ dehydration of the alcohol (e.g., methanol) to hydrocarbons, and particularly the LPG hydrocarbons propane and/or butane. The incorporation of a stabilizer such as platinum and/or yttrium (e.g., as yttria or yttrium oxide) can benefit these catalyst systems, particularly in terms of improving their activity and/or stability. Other advantages may be realized by the incorporation of promoters such as manganese (Mn), magnesium (Mg), and/or silicon (Si) into these catalyst systems, such as to improve selectivity to, and/or yield of, desired LPG hydrocarbons.
Catalyst binders for filter substrates
Provided is a catalyst washcoat comprising (i) a molecular sieve loaded with about 1 to about 10 weight percent of at least non-aluminum promoter metal (wherein the promoter metal weight percent is based on the weight of the molecular sieve); and (ii) about 1 to about 30 weight percent of a binder having a d90 particle size of less than 10 microns (wherein the binder weight percent is based on the total weight of the washcoat). In another aspect of the invention, the catalyst washcoat is applied to a wall-flow filter to form a catalyst article. In another aspect of the invention the catalyst article is part of an exhaust gas treatment system. And in yet another aspect of the invention, provided is a method for treating exhaust gas using the catalyst article.

Systems and methods for cracking hydrocarbon streams utilizing cracking catalysts
According to one or more embodiments, a hydrocarbon feed stream may be cracked by a method comprising contacting the hydrocarbon feed stream with a cracking catalyst in a reactor unit. The hydrocarbon feed stream may have an API gravity of at least 40 degrees. The cracking catalyst may comprise one or more binder materials, one or more matrix materials, and *BEA framework type zeolite.
FCC catalyst compositions containing boron oxide
Described are fluid catalytic cracking (FCC) compositions, methods of manufacture and use. FCC catalyst compositions comprise particles containing a non-zeolitic component and one or more boron oxide components. In embodiments, the FCC catalyst composition contains a zeolite component and optionally a rare earth component and a transition alumina. FCC catalytic compositions may comprise a first particle type containing one or more boron oxide components and a first matrix component mixed with a second particle type containing a second matrix component, and a zeolite. The FCC catalyst compositions can be used to crack hydrocarbon feeds, particularly resid feeds containing high V and Ni, resulting in lower hydrogen and coke yields.
Selective process and catalysts for the production of renewable fuels and distillates of high molecular weight
The present invention relates to a process for the conversion of plant oils, animal fats, waste food oils and carboxylic acids into renewable liquid fuels, such as bio-naphtha, bioQAV and renewable diesel, for use in combination with fossil fuels. The process is composed of two steps: hydrotreatment and hydrocracking. The effluent from the hydrotreatment step contains aromatics, olefins and compounds resulting from the polymerization of esters and acids. This is due to the use of partially reduced catalysts without the injection of a sulfiding agent and allows for the production of bioQAV of suitable quality for use in combination with fossil kerosene. Concurrently, the process generates, in addition to products in the distillation range of naphtha, kerosene and diesel, high molecular weight linear paraffins (up to 40 carbon atoms).
