    Abstract: A class of catalysts which exhibit superior activity maintenance in dehydrocyclization reactions are defined as a type L zeolite having exchangeable cations of which at least 75% are selected from Group IA and calcium and barium cations and containing well dispersed particles of at least one Group VIII noble metal where at least 90% of the noble metal prior to reduction thereof is dispersed in the form of particles having a diameter less than 7 .ANG.. The catalysts may also be identified as type L zeolites loaded with at least one Group VIII noble metal which have a terminal cracking index (as a measure of production of pentanes versus butanes from hexane) of at least 1.5.

    Abstract: An improved catalyst for the synthesis of ammonia is described wherein a promoted iron-derived, pre-reduced catalyst is oxidatively leached with a neutral aqueous solution of potassium cyanide. Preferably an organic carboxylic acid such as citric acid is added to the aqueous solution to maintain the pH at about neutral. The resulting leached catalyst has a markedly higher activity than the unleached catalyst. The leached catalyst may be contacted with a cobalt complex or a nickel salt to incorporate cobalt or nickel therein which catalysts are also useful for ammonia synthesis.

    Abstract: A process comprising passing a first stream comprising residual oil and hydrogen downwardly through a zone containing hydrodesulfurization catalyst under hydrodesulfurization conditions until said catalyst is deactivated. Subsequently, passing a second stream of residual oil and hydrogen upwardly through the deactivated hydrodesulfurization catalyst under thermal cracking conditions, including a temperature above the hydrodesulfurization temperature.

    Abstract: Disclosed is a method for preparing dual colloid catalyst compositions wherein a gel, or colloidal suspension is formed by admixing (a) a 0.6 to 10M aqueous solution containing one or more soluble salts or complexes of one or more transition metals, wherein at least one of the transition metals is reducible and hydrolyzable, and one or more elements selected from Cr, Al, Si, Th, U, the lanthanides, and elements from Groups IA and IIA of the Periodic Table of the Elements, with (b) a 0.5 to 10N aqueous base solution. The solid material is separated from the resulting gel, or colloidal suspension and washed and dried.
