摘要： The present invention is related to a process for the preparation of zeolitic material through condensed gel crystallizations and their use in an FCC Catalyst composition. The present disclosure describes methods for improved preparation of zeolites by preparing an aqueous precursor mixture; removing at least 5 wt % of the total water from the aqueous precursor solution to create a solution with greater solids content; crystallizing the solution of step (b) to create a zeolite product. The resulting zeolite is used in an FCC catalyst composition comprising about 2 to about 80 wt % one or more zeolite, about 15 to about 50 wt % quasicrystalline boehmite, about 0 to about 50 wt % microcrystalline boehmite, and greater than about 0 to about 25 wt % silica.

摘要： A catalytic cracking agent has an active component consisting of a phosphorus-modified molecular sieve and a non-phosphorus-modified molecular sieve or only consisting of a phosphorus-modified molecular sieve. According to an electron probe microanalysis (EPMA), the D value of phosphorus in the catalytic cracking agent is ≥65%, preferably ≥68%, provided that the active component consists of the phosphorus-modified molecular sieve and the non-phosphorus-modified molecular sieve, or the D value of phosphorus in the catalytic cracking agent is ≥82%, preferably ≥84%, provided that the active component only consists of the phosphorus-modified molecular sieve.

摘要： Systems and methods for processing a plastic are disclosed. The system includes a feeding device in fluid communication with a cracking unit. A feed stream comprising a plastic is depolymerized in the feeding device at a depolymerization temperature to produce a hydrocarbonaceous wax stream. The hydrocarbonaceous wax stream is then cracked in the cracking unit. The cracking is conducted at a cracking temperature that is lower than, or the same as the depolymerization temperature.

摘要： The present invention relates to a core-shell composite catalyst, wherein the core is a spinel-structure XYaOb catalyst, wherein X and Y, being different from each other, are metal elements selected from main group II, transition elements and main group III of the Periodic Table of Elements; a is a number between 1-15, preferably between 1-5; b is the number of oxygen atoms required to satisfy the valence of the elements; the shell is a molecular sieve catalyst, preferably selected from one or more of ZSM-5, ZSM-11, ZSM-35 and MOR, more preferably selected from ZSM-5 and ZSM-11. When the core-shell composite catalyst is used for preparing p-xylene directly from syngas in one step, the process is simple and easy to operate; the selectivity toward p-xylene in xylene products is high; the conversion of syngas is high; and the service life of the catalyst is long. In addition, the present invention also relates to the preparation method of core-shell composite catalyst, and use thereof as the catalyst in the one-step preparation of p-xylene from syngas.

摘要： An improved MFI zeolite having low aluminum occupation at intersection sites characterized by an ortho-xylene to para-xylene uptake ratio of 0.1 to about 0.55. Processes for converting hydrocarbon or oxygenate to a product comprising light olefins and/or aromatics using the improved MFI zeolite as catalyst are also disclosed. Para-xylene in the product may be greater than about 24% of the xylenes.

摘要： Catalytic compositions for depolymerizing polyolefin-based waste material into useful petrochemical products and methods of use are described. The compositions are a composite of at least one zeolite catalyst with one or more co-catalyst(s) that is a solid inorganic material. These composite catalysts, along with heat, are used to both increase the depolymerization reaction rate of the feed streams and suppress poisoning effects of non-polyolefin polymers that may be present. This results in a shorter residence time in the depolymerization unit and more efficient process.

摘要： The technology relates to a method of preparing a supported molybdenum catalyst, using a simultaneous acid-base mediated ion exchange process and continually monitoring pH, where molybdenum ions are dispersed inside zeolite channels and located in proximity to the acidic aluminum sites. This process leads to high catalytic activity and resistance to deactivation.

摘要： The present invention addresses to a process for the production of aromatic compounds from streams containing linear chains with 5 to 18 carbon atoms, of fossil or renewable origin, and application in the field of catalytic cracking aiming at a regenerator operation at much lower temperature, between 480° C. and 620° C., preferably the temperature should be between 500° C. and 600° C. The coked catalyst generated by the cracking of light streams with low potential for delta coke generation can have the combustion effected at a lower temperature. The regeneration temperature must be at least 40° C. and at most 100° C. higher than the reaction temperature, keeping the catalyst circulation high to maintain the energy balance in the reaction section. The minimum regeneration temperature can be ensured by installing an air preheating furnace before entering the regenerator and passing through the air distributor inside the regenerator. The used catalyst must contain zeolite with pores of intermediate size. Such conditions greatly favor the production of aromatics and the octane rating of the produced naphtha.

摘要： A process for producing olefins from the hydrocarbon feed includes introducing the hydrocarbon feed into a Solvent Deasphalting Unit (SDA) to remove asphaltene from the hydrocarbon feed producing a deasphalted oil stream, wherein the SDA comprises a solvent that reacts with the hydrocarbon feed, and the deasphalted oil stream comprises from 0.01 weight percent (wt. %) to 18 wt. % asphaltenes; introducing the deasphalted oil stream into a steam catalytic cracking system; steam catalytically cracking the deasphalted oil stream in the steam catalytic cracking system in the presence of steam and a nano zeolite cracking catalyst to produce a steam catalytic cracking effluent; and separating the olefins from the steam catalytic cracking effluent.
