Abstract
Official abstract text for this publication.
A method for producing formaldehyde from methanol. The method includes the steps of packing a catalyst comprising platinum, bismuth and a support material into a reactor, introducing a reactant mixture containing methanol into the reactor such that the reactant mixture containing methanol is in close contact with the catalyst, and heating the reactant mixture containing methanol to a temperature for a period of time.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for producing formaldehyde from methanol, the method comprising: packing a catalyst comprising platinum, bismuth and a support material into a reactor; introducing a reactant mixture containing methanol into the reactor such that the reactant mixture containing methanol is in close contact with the catalyst; and heating the reactant mixture containing methanol to a temperature for a period of time. 2. The method of claim 1 , wherein the operating temperature is in the range 273 K-423 K. 3. The method of claim 1 , wherein the reactant mixture includes an inert gas. 4. The method of claim 3 , wherein the inert gas is one of argon, helium and nitrogen. 5. The method of claim 1 , wherein platinum loading in the catalyst is in the range of 0.1-5.0 weight %. 6. The method of claim 1 , wherein bismuth loading in the catalyst is in the range of 0.1-5.0 weight %. 7. The method of claim 1 , wherein the support material is one of activated carbon and SiO 2 . 8. The method of claim 1 , wherein the particle size of the support material is from 200 mesh to 10 mesh. 9. The method of claim 1 , the reactor is a tubular reactor.
