ALLOYED ZEOLITE CATALYST COMPONENT, METHOD FOR MAKING AND CATALYTIC APPLICATION THEREOF
The presently disclosed and claimed inventive concept(s) generally relates to a method of making a solid catalyst component comprising a zeolite with a modifier and at least one Group VIII metal alloyed with at least one transition metal and a process of converting mixed waste plastics into low molecular weight organic compounds using the solid catalyst component. The process of converting mixed waste plastics into low molecular weight organic compounds may employ the use of a non-thermal catalytic plasma reactor, which may be configured as a fluid bed reactor or fixed bed reactor.
Hydrocracking catalyst for heavy fraction of bio-oil, method for preparing the same and method for bio-oil upgrading using the same
Disclosed herein are a catalyst for hydrocracking reaction of high molecular weight components in bio-oil, a method for preparing the same and a method for bio-oil upgrading using the same. The catalyst includes a zeolite carrier; and at least one metal selected from the group consisting of nickel (Ni), ruthenium (Ru) and cerium (Ce) supported on the carrier. The catalyst promotes the hydrocracking of high molecular weight compounds contained in the bio-oil, but also inhibits the polymerization reaction of the decomposed product, thereby more effectively enhancing the hydrocracking reaction of the bio-oil.

Phosphorus-containing rare-earth-containing MFI structure molecular sieve rich in mesopore, preparation method, and catalyst containing same and application thereof
A rare earth- and phosphorus-containing molecular sieve of MFI structure rich in mesopores has a ratio of n(SiO.sub.2)/n(Al.sub.2O.sub.3) of more than 15 and less than 70. The molecular sieve has a content of phosphorus of 1-15 wt %, calculated as P.sub.2O.sub.5 and based on the dry weight of the molecular sieve. The content of the supported metal in the molecular sieve is 1-10 wt % supported metal M1 and 0.1-5 wt % supported metal M2 based on the oxide of the supported metal and the dry weight of the molecular sieve. The supported metal M1 is one or two selected from lanthanum and cerium, and the supported metal M2 is one selected from iron, cobalt, nickel, copper, manganese, zinc, tin, bismuth and gallium; the volume of mesopores in the molecular sieve represents 40-70% by volume of the total pore volume of the molecular sieve by volume.
SELECTIVE HYDROCRACKING OF NORMAL PARAFFINS
Provided is a process for hydrocracking normal paraffins into lighter normal paraffins with minimal formation of iso-paraffins. The process comprises hydrocracking a hydrocarbon feedstock comprising normal paraffins under hydrocracking conditions. The reaction is run in the presence of a selected catalyst, e.g., an LTA-type zeolite, with a requisite topology and acid site density. The zeolite has a framework type with voids greater than 0.50 nm in diameter, which are accessible through apertures characterized by a longest diameter of less than 0.50 nm and a shortest diameter of more than 0.30 nm. The reaction conducted in the presence of such a selected zeolite produces an n-paraffin rich product.
PROMOTOR FOR ACTIVE PHASE METALS DISPERSION IN HYDROPROCESSING CATALYSTS AND METHOD OF MAKING THE CATALYST
A composition comprising a promotor component is disclosed comprising a mixture of one or more catalytically active components and one or more oxidized disulfide oil (ODSO) compounds, including a water-soluble fraction of ODSO. A composition comprising an aqueous solution of one or more catalytically active components and a promotor component is also disclosed. In certain embodiments the ODSO is obtained from the effluent of an enhanced MEROX process. The compositions facilitate transfer of catalytically active components (or components that will be catalytically active in the finished solid catalyst material) onto the surface of support materials.
Method for manufacturing of multi-level pore zeolite and utilization as catalyst for hydroisomerization of normal paraffins of multi-level pore zeolite prepared thereby
The present disclosure relates to a method for preparing a multi-level pore zeolite, including: (A) a step of mixing a silicon precursor, an aluminum precursor, a phosphorus precursor, a structure directing agent and water; a step of (B) adding phenylphosphonic acid, carbon black or a mixture thereof to the mixture prepared in the step (A) and mixing the same; a step of (C) crystallizing the mixture prepared in the step (B) by heat-treating the same; and a step of (D) calcining the crystallization product, and utilization of the prepared multi-level pore zeolite as a catalyst for hydroisomerization of normal paraffins. The catalyst exhibits improved isoparaffin yield when it is used as a catalyst for hydroisomerization of normal paraffins such as diesel or lube base oil by supporting an active metal component because residence time of reactants and products in the zeolite crystals are decreased due to mesopores and the proportion of external acid sites to total acid sites is low. Also, cloud point and pour point are effectively improved and high hydroisomerization reactivity is achieved without product loss.
