  • Patent number: 9573847
    Abstract: The present invention is directed to a method of continuously calcining a limestone particle mix comprising a fine fraction of limestone particles and a coarser fraction of limestone particles. The limestone particles heat treated in a flash calciner in which the mixture is entrained and heated in process gas for an amount of time sufficient to fully calcine the fine fraction but not the coarser fraction. The process gas is separated from the heated limestone mixture. The mixture is directed to a retention vessel in which the mixture is retained for an amount of time sufficient to fully calcine the coarser fraction utilizing the process heat present in the limestone mixture. No external heat needs to be added to the retention vessel during the retention step to promote calcination.

  • Patent number: 9573865
    Abstract: A process for increasing the yield of C3 olefin in fluidized bed catalytic cracking of hydrocarbon feedstocks is disclosed. C4 fraction produced from the cracking of hydrocarbon feedstock in the primary reaction zone (riser), optionally with external source of C4 stream is fed into the stripper which acts as a secondary reaction zone at an elevated temperature and at an optimum WHSV. The elevated temperature is achieved by injecting a part of the regenerated catalyst from regenerator, which is at a higher temperature, directly into the stripper through a dedicated additional lift line. This raises the activity of catalyst inside the stripper. The direct injection of regenerated catalyst into the stripper, besides producing higher yields of propylene, improves the stripping efficiency leading to enhanced recovery of strippable hydrocarbons.

  • Patent number: 9573884
    Abstract: Fatty amide compositions and their derivatives are disclosed. The fatty amides comprise a reaction product of a metathesis-derived C10-C17 monounsaturated acid, octadecene-1,18-dioic acid, or their ester derivatives with a primary or secondary amine. Derivatives made by reducing, quaternizing, sulfonating, alkoxylating, sulfating, and sulfitating the fatty amide are also included. The amine reactant can be diethylenetriamine or (2-aminoethyl)ethanolamine, which provide imidazoline amides or esters, respectively. In one aspect, the ester derivative of the C10-C17 monounsaturated acid or octadecene-1,18-dioic acid is a lower alkyl ester. In other aspects, the ester derivative is a modified triglyceride made by self-metathesis of a natural oil or an unsaturated triglyceride made by cross-metathesis of a natural oil with an olefin. The compositions are valuable for cleaners, fabric treatment, hair conditioning, personal care, antimicrobial compositions, agricultural uses, and oil field applications.
