Abstract
An improved reactor for chemical reaction includes a wetproofed catalyst therein for increasing the rate of reaction between the reactants and/or controlling selectivity of the products, if there is more than one reaction product. The wetproofed catalyst may be used in addition to the other catalytic systems already known in the art. The reaction occurs in the presence of two or more fluid phases. The types of reaction may be reduction-oxidation, hydration and the like. The wetproofed catalyst is a solid, particulate catalyst including surface portions which are wetproofed so that the catalyst is not flooded by any of the reactants, reaction products or other fluids in the reaction chamber. Wetproofing of the surface portions of the catalyst may be accomplished in various ways, as described, and various materials may be used for the catalyst. Reaction conditions may be subambient temperature and pressure, to elevated temperature and pressure and the reaction may be operated on a batch, batch continuous, or continuous basis. It is important that each reactant contact the catalyst and each other, but that neither reactant flood the catalyst. The reaction chamber is of relatively simp…
