In order to increase the amount of catalytic metal which can be incorporated in a zeolite catalyst by contact of zeolite with solution of a given amount of chemical containing the catalytic metal, or conversely to reduce the amount of such chemical needed to incorporate a given desired amount of catalytic metal in the catalyst, a zeolite containing a cation, e.g., sodium, replaceable by ammonium ion, is contacted with an aqueous solution of ammonium metalate, e.g., molybdate, and a second ammonium compound, e.g., ammonium chloride, said second ammonium compound providing additional anion for balancing the change of said cation in the solution.
An oil spill recovery system for removal of oil spill contaminants from the surface of a body of water has a suction blanket which can be deployed by a host vessel, there being a plurality of air pressure lines through the blanket with suction ports to induce the flow of water and any oil spill in communication with the ports through the conduits into a common collection chamber, and the contaminants can then be exhausted or removed from the collection chamber as necessary and separately collected.
The invention features metal-containing catalysts including a crystalline microporous metal oxide structure encapsulating an amount of metal which reflects the amount of metal introduced into the metal oxide structure.
