PEPTIZATION AGENT AND SOLID CATALYST MANUFACTURING METHOD
Methods of solid catalyst manufacture using a peptization agent, a peptization agent, and formed solid catalyst materials are provided. The peptization agent includes one or more oxidized disulfide oil (“ODSO”) compounds. These ODSO compounds peptization agents are used to replace conventional acids used as peptization agents.
Acrylic acid, and methods of producing thereof
Provided herein are methods of producing acrylic acid from beta-propiolactone. Such methods may involve the use of a heterogeneous catalyst, such as a zeolite.
Method for selectively chemically reducing CO.SUB.2 .to form CO
A method for selectively chemically reducing CO.sub.2 to form CO includes providing a catalyst, and contacting H.sub.2 and CO.sub.2 with the catalyst to chemically reduce CO.sub.2 to form CO. The catalyst includes a metal oxide having a chemical formula of Fe.sub.xCo.sub.yMn.sub.(1−x−y)O.sub.z, in which 0.7≤x≤0.95, 0.01≤y≤0.25, and z is an oxidation coordination number.
High activity and high distillate yield hydrocracking catalysts with intimate interaction between unsupported metal oxide and zeolite
A hydroprocessing catalyst with improved performance has been produced that involves an intimately mixed unsupported metal oxide with a zeolite or other acid function. The intimate mixing allows an intimate interaction between the unsupported metal oxide and the acid function. The hydroprocessing catalyst may be used alone or may be incorporated with a portion of a conventional hydrocracking catalyst.
MOLECULAR SIEVE SSZ-121 WITH HIGH ACIDITY, ITS SYNTHESIS AND USE
A novel synthetic crystalline aluminogermanosilicate molecular sieve material, designated SSZ-121 is provided which exhibits increased acidity. The SSZ-121 can be synthesized using 1,3-bis(1-adamantyl)imidazolium cations as a structure directing agent. The synthesis employs a boron pathway to achieve increased acid sites. The SSZ-121 of increased acidity may be used in organic compound conversion reactions and/or sorptive processes.
MOLECULAR SIEVE SSZ-113 WITH HIGH ACIDITY, ITS SYNTHESIS AND USE
A novel synthetic crystalline molecular sieve material, designated SSZ-113 is provided which exhibits increased acidity. The SSZ-113 can be synthesized using 1,3-bis(2,3-dimethyl-1H-imidazolium)propane dications as a structure directing agent. The synthesis employs a boron pathway to achieve increased acid sites. The SSZ-113 of increased acidity may be used in organic compound conversion and/or sorptive processes.
BIOLOGICALLY APPLICABLE WATER-SOLUBLE HETEROGENEOUS CATALYSTS FOR PARA-HYDROGEN INDUCED POLARIZATION
A heterogeneous catalyst composition for para-hydrogen induced polarization includes ligand-capped nanoparticles dispersed in water. The ligand-capped nanoparticles include metal nanoparticles that are surface functionalized with organic ligands, a molecular weight of the organic ligands is no greater than 300 g/mol, and the organic ligands each includes multiple binding moieties as coordinates sites for binding to a nanoparticle surface.
FCC catalyst prepared by a process involving more than one silica material
Process for the preparation of a catalyst and a catalyst comprising more than one silica is provided herein. Thus, in one embodiment, the invention provides a particulate FCC catalyst comprising about 5 to about 60 wt % one or more zeolites, about 10 to about 45 wt % quasicrystalline boehmite (QCB), about 0 to about 35 wt % microcrystalline boehmite (MCB), greater than about 0 to about 15 wt % silica from sodium stabilized colloidal silica, greater than about 0 to about 30 wt % silica from ammonia stabilized or lower sodium colloidal silica, and the balance clay and the process for making the same. This process results in attrition resistant catalysts with good performance.
HETEROGENEOUS CATALYSTS, AND USES THEREOF
Provided herein are heterogeneous catalysts suitable for use in carbonylation reactions, including the production of acrylic acid from ethylene oxide and carbon monoxide on an industrial scale. The production may involve various unit operations, including, for example: a beta-propiolactone production system configured to produce beta-propiolactone from ethylene oxide and carbon monoxide; a polypropiolactone production system configured to produce polypropiolactone from beta-propiolactone; and an acrylic acid production system configured to produce acrylic acid with a high purity by thermolysis of polypropiolactone.
Processes for Upgrading Alkanes and Alkyl Aromatic Hydrocarbons
Processes for upgrading a hydrocarbon. The process can include introducing, contacting, and halting introduction of a hydrocarbon-containing feed into a reaction zone. The feed can be contacted with a catalyst within the reaction zone to effect dehydrogenation, dehydroaromatization, and/or dehydrocyclization of the feed to produce a coked catalyst and an effluent. The process can include introducing, contacting, and halting introduction of an oxidant into the reaction zone. The oxidant can be contacted with the coked catalyst to effect combustion of the coke to produce a regenerated catalyst. The process can include introducing, contacting, and halting introduction of a reducing gas into the reaction zone. The reduction gas can be contacted with the regenerated catalyst to produce a regenerated and reduced catalyst. The process can include introducing and contacting an additional quantity of the feed with the regenerated and reduced catalyst to produce a re-coked catalyst and additional first effluent.
