  • Low acid inventory alkylation
    Patent number: 5120895
    Abstract: A process and apparatus are disclosed for acid continuous alkylation of a hydrocarbon-containing feedstream in which the inventory of acid is reduced. The apparatus used combines a reactor, settler and heat exchanger in a single vessel. The acid phase flows out of the reactor only for acid makeup, to account for acid consumption, and regeneration.

  • Zeolite-clay composition and uses thereof
    Patent number: 5079201
    Abstract: A hydrous aluminosilicate adsorbent composition in which the active adsorbent is a mixture of non-fibrous clay with non-fibrous zeolite. The composition is useful as a feed supplement in animal husbandry, and as a topical adsorbent for veterinary use. The mixture has a high capacity for adsorption of ammonium cations, and a synergistically high selectivity for their adsorption. Beneficial effects as feed supplement may arise from lowering the amount of ammonia passed to the liver from the alimentary canal.
