Abstract: According to one or more embodiments, the flow of catalyst in a fluidized catalytic processing system may be controlled by a method including determining the amount of catalyst present in a first catalyst bed of the fluidized catalytic processing system. The fluidized catalytic processing system may include a first catalyst bed, a second catalyst bed, a third catalyst bed, and a fourth catalyst bed. The method may include comparing the amount of catalyst present in the first catalyst bed with a threshold catalyst amount. When the amount of catalyst present in the first catalyst bed is less than the threshold catalyst amount, the method may include regulating flow of catalyst from the second catalyst bed to the third catalyst bed such that an increased target amount of catalyst is maintained in the second catalyst bed.

Abstract: Disclosed in embodiments herein are ionomers and methods of making the same. The ionomers comprise a neutralized blend of olefin-carboxylic acid copolymers and Group II, Group IIIA, and transition metal salts. The method includes mixing an acid copolymer formed from an ?-olefin monomer and an ?,?-ethylenically unsaturated carboxylic acid having at least one carboxylic acid group with an amine-containing aqueous solution to form an aqueous dispersion containing an amine salt of the acid copolymer. The method further includes mixing a solution of a Group IIA , Group IIIA, or transition metal salt with the aqueous dispersion containing the amine salt of the acid copolymer to exchange at least a portion of the amine salt for the Group IIA , Group IIIA, or transition metal salt, thereby forming the ionic copolymer.
Abstract: Organic isocyanates are converted to ureas by heating in the presence of certain cobalt, magnesium, chromium and lanthanide series organometallic catalysts. The process requires no water or other reactants. The process is particularly useful for removing small quantities of monoisocyanates from a solvent stream recovered from a polyisocyanate manufacturing process. The urea compounds in some instances can be recycled back into the polyisocyanate manufacturing process and reacted with polyisocyanate compounds to form biurets.

Abstract: Alkyl ether amines are used as foam control compounds in foodstuff processing. The alkyl ether amines can be used at various stages during industrial processing of vegetables, fruits, and plants, such as potatoes and beets. The alkyl ether amines are generally of lower molecular weights and therefore easily transported to the foam layer to break the foam structure. Further, the alkyl ether amines are water soluble and therefore can be readily removed from the food processing system.

Abstract: Chemical formulations for chemical products can be represented by digital formulation graphs for use in machine learning models. The digital formulation graphs can be input to graph-based algorithms such as graph neural networks to produce a feature vector, which is a denser description of the chemical product than the digital formulation graph. The feature vector can be input to a supervised machine learning model to predict one or more attribute values of the chemical product that would be produced by the formulation without actually having to go through the production process. The feature vector can be input to an unsupervised machine learning model trained to compare chemical products based on feature vectors of the chemical products. The unsupervised machine learning model can recommend a substitute chemical product based on the comparison.

Abstract: Monoisocyanate impurities are removed from a process stream obtained when solvent is separated from a polyisocyanate product. The monoisocyanates are reacted with amine compounds at specific molar ratios to produce ureas. The ureas can be discarded by burning, landfilling or otherwise. Alternatively the ureas can be recycled back into the polyisocyanate manufacturing process, where they are formed into biuret compounds that can remain with the polyisocyanate product.
