Partial Oxidation Of Methane. With the catalysis of K 2 PdCl 4 and H 5 PMo 10 V 2 O 40 in CF 3 COOH methane can be oxidized into CH 3 COOH and CF 3 COOCH 3 using molecular oxygen as the oxidant at a. Although HCHO selectivities in excess of 85 could be obtained at very low conversions sodium contamination as low as 300 ppm Na was found to lower both activity and selectivity to formaldehyde. Noncatalytic partial oxidation of methane occurs only at very high temperatures. Among the alternatives the catalytic partial oxidation for the production of synthesis gas from methane CPOM is more energy efficient since it has fast kinetics and is exothermic thus avoiding the need of large reactors and large amounts of.

POM in fixed-bed reactors requires an oxygen separation plant with high operation cost and safety risks. However the high reaction temperature required in thermocatalysis decreases the costperformance ratio. Hwang 2 a and Nam Hwi Hur 1 b. Cernik1 and Andrew M. The Cu 2 O 2 2 site is found to be active for the partial oxidation of methane to methanol and although it has a higher energy barrier in the methane activation step it involves a very low energy barrier in the methanol formation step 363 kJ mol 1 as well as a lower methanol desorption energy 525 kJ mol 1. Although methane is the simplest hydrocarbon which gives formaldehyde and methanol as partial oxidation products the direct utilization of these reactions for the manufacture of formaldehyde and methanol has remained extremely difficult.
