متن کاملAtmospheric methanol measurement using selective catalytic methanol to formaldehyde conversion
A novel atmospheric methanol measurement technique, employing selective gas-phase catalytic conversion of methanol to formaldehyde followed by detection of the formaldehyde product, has been developed and tested. The effects of temperature, gas flow rate, gas composition, reactor-bed length, and reactor-bed composition on the methanol conversion efficiency of a molybdenum-rich, ironmolybdate ca...
متن کاملCarbon dioxide/methanol conversion cycle based on cascade enzymatic reactions supported on superparamagnetic nanoparticles.
The conversion of carbon dioxide into important industrial feedstock is a subject of growing interest in modern society. A possible way to achieve this goal is by carrying out the CO2/methanol cascade reaction, allowing the recycle of CO2 using either chemical catalysts or enzymes. Efficient and selective reactions can be performed by enzymes; however, due to their low stability, immobilization...
متن کاملBiochemistry of methanol poisoning. III. The enzymic pathway for the conversion of methanol to formaldehyde.
Abstrsct—An enzyme system capable of oxidizing both methanol and ethanol in the 0 presence of DPN was purified almost nine ty-fold from the liver of the rhesus monkey. Data for theK, values for the two alcohols and DPN and for the R values in the presence of some inhibitors are presented. The enzyme ap rs to be identical to liver alcohol hydrogenase AD 1. Eihlili competitively inhibited the oxi...
متن کاملOxidation of methanol to formaldehyde on supported vanadium oxide catalysts compared to gas phase molecules.
The oxidation of methanol to formaldehyde on silica supported vanadium oxide is studied by density functional theory. For isolated vanadium oxide species silsesquioxane-type models are adopted. The first step is dissociative adsorption of methanol yielding CH3O(O=)V(O-)2 surface complexes. This makes the O=V(OCH3)3 molecule a suited model system. The rate-limiting oxidation step involves hydrog...
