Abstract: The production of formaldehyde by oxidizing dehydrogenation of methanol in the presence of a silver catalyst which consists of three or more layers each of specific weight and particles of specific particle size and having a specific total layer thickness. Formaldehyde prepared according to the process of the invention is a disinfectant, tanning agent, reducing agent and valuable starting material for the production of synthetic resins, adhesives and plastics.

Abstract: Sulfur-free combustion gases of low soot content are produced by mixing oxygen and an off-gas of a defined composition in a defined weight ratio, passing the final mixture thus obtained through a defined number of slit channels of gas burners into a combustion chamber and combusting it at a defined temperature. Compared to the prior art, the process of the invention gives sulfur-free combustion gases, containing little or no soot (in general containing no detectable soot), more simply and more economically. These gases are used for heating, in particular for raising steam.

Abstract: Formaldehyde is manufactured by oxidative dehydrogenation of methanol in the presence of a silver catalyst and of certain amounts of steam and formaldehyde, some formaldehyde and a part of the water being withdrawn from the reaction mixture and recycled. The formaldehyde manufactured by the process may be used as a disinfectant, tanning agent, reducing agent and starting material for the manufacture of synthetic resin, adhesives and plastics.
