METAL MOLYBDATE/IRON-MOLYBDATE DUAL CATALYST BED SYSTEM AND PROCESS USING THE SAME FOR METHANOL OXIDATION TO FORMALDEHYDE |
摘要 |
A process and fixed bed reactor for oxidizing methanol in a reactant gas feed stream to formaldehyde. The process comprises introducing the reactant gas feed stream into an upstream region containing a first metal molybdate catalyst (substantially free of a volatile Mo/MoO3 species) under oxidizing conditions to form a partially oxidized reactant gas feed stream which is then introduced under oxidizing conditions into a downstream region containing a second metal molybdate catalyst to further oxidize any residual methanol contained therein. A fixed bed reactor comprising an upstream region and a downstream region containing the aforementioned first and second metal molybdate catalysts, respectively, is utilized to implement the inventive process to yield a product gas stream containing formaldehyde preferably at a conversion of 85 % or more and a selectivity of 90 % or more. |
