    Abstract: A method of coating a catalyst to a support for use in acrolein oxidation reaction. Metallic salt components of the catalyst including molybdate, vanadate and tungstate are dissolved in a liquid to form a suspension of particles of the catalyst. The precipitation of the catalyst particles is controlled by homogenizing the catalyst particles suspended in the liquid. The phase separation between the catalyst particles and the liquid can be substantially slowed down by the homogenization. Then the catalyst is coated on an inert support by applying the suspension of the catalyst particles to the support. In the suspension, the total weight of water is about 0.8 to about 5 times of the total weight of the metallic salts in the catalyst. This method of preparing suspension minimizes the amount of the liquid required to dissolve the metallic salts, which reduces the amount of time and energy to be used in evaporating the liquid from the suspension. Additionally, in obtaining catalyst from the suspension prepared by this method, it is possible to avoid the deterioration of the catalytic performance since less heat is required to evaporate the water.

    Abstract: A process and catalyst for the partial oxidation of paraffinic hydrocarbons, such as ethane, propane, naphtha, and natural gas condensates, to olefins, such as ethylene and propylene. The process involves contacting a paraffinic hydrocarbon with oxygen in the presence of a catalyst under autothermal process conditions. The catalyst comprises a Group 8B metal and, optionally, a promoter metal, such as tin or copper, supported on a fiber monolith support, preferably a ceramic fiber mat monolith. In another aspect, the invention is a process of oxidizing a paraffinic hydrocarbon to an olefin under autothermal conditions in the presence of a catalyst comprising a Group 8B metal and, optionally, a promoter metal, the metals being loaded onto the front face of a monolith support. An on-line method of synthesizing and regenerating catalysts for autothermal oxidation processes is also disclosed.

    Abstract: This invention relates to methods for spraying liquid compositions containing volatile solvent by using compressed fluids, such as carbon dioxide or ethane, to form solid particulates, coating powders, and catalyst materials, which can be produced with narrow particle size distributions and can be sprayed at higher solids levels, in ambient air or with heated air applied to just the spray instead of a spray chamber. Novel catalyst supports can be produced having a beneficial morphology such as for olefin catalysis. Drier water-borne coatings can be applied to substrates by using compressed fluids to spray water-borne coating compositions having conventional water levels, thereby reducing runs and sags and shortening dry times.
