Abstract: Detergent type alkylaryl sulfonates are prepared by separating normal paraffins from a petroleum fraction, dehydrogenating the normal paraffins to form mono-olefins, reacting the mono-olefins with a monocyclic aryl compound such as benzene and sulfonating the resulting alkylaryl hydrocarbons. Novel dehydrogenation catalysts comprising cobalt, zinc or mixtures, or oxides thereof and one or more noble metals of the platinum or palladium families deposited upon low acidity alumina are employed for the dehydrogenation of n-paraffins. The procedure using such novel catalysts results in improved conversions and the production of a purer product.

Abstract: The present invention relates to a method for preparing, activating and regenerating a metal supported catalyst, comprising: treating a Ma-Mb-Mc metal supported catalyst at 10-700° C. by using an ammonia or nitrogen-containing organic matter, wherein the Ma metal is an active metal selected from one or more of a noble metal atom or a transition metal, the support is a common industrial porous catalyst, and the Ma metal is dispersed on the support in a state of single atomic site. According to the Md-Mb-Mc metal supported noble metal/zinc catalyst treated by the method of the present invention, the direct dehydrogenation conversion rate and selectivity of catalyzing light alkanes are remarkably improved; the method for preparing the catalyst is simple in process, the catalytic activity after regeneration is still kept, and the catalyst can be industrially produced on a large scale.

Abstract: A method for preparing acrylic acid, more specifically, to a method for preparing acrylic acid under a neutral condition at high yield in a short time without using a base, unlike the prior art in which a base is essentially used. The acrylic acid is produced using a supported catalyst having a specific composition when preparing acrylic acid by oxidation of allyl alcohol. Particularly, the preparation method can recover acrylic acid rather than acrylic acid salt as a final product, and thus has an advantage that the overall process cost can be reduced by eliminating essential processes in the prior art, such as ion exchange after the acidification process required for the conversion of acrylic acid salt to acrylic acid.
