The patent describes a process for the selective oxidation of methane to methanol using ferric sulphate in acid aqueous solution at a pH of less than 3. This solution is the oxygen carrier and is allowed to trickle through a packed bed of catalyst. The flow of ferric sulphate solution and methane is countercurrent.

Copper: Cupric oxide is also a highly active catalyst for the deep oxidation of CO, methane, methanol, ethanol, and acetaldehyde, and is also used to catalyze the oxidation of methanol to methyl formate and propylene to acrolein. Mixed Oxide Catalysts

Iridium-based catalysts are highly active for the catalytic oxidation of methane to methanol using molecular oxygen as the oxidant in the presence of CO in aqueous solution, under mild conditions. The performance of Ir-ZSM-5 catalyst can be significantly enhanced by adding copper and palladium promoters.

Additionally, since the Pt II Cl x (H 2 O) (4–x) (2–x) catalyst displays modest selectivity for methane versus methanol oxidation (∼1:1) (SI, Table S8), 11 strategies for continuous product removal would be needed to minimize overoxidation. As opposed to a volatile chemical oxidant that may be released at a similar rate as the methanol product, electrochemical oxidation could allow for independent control of oxidant delivery and product release.

Catalytic transformation of methane (CH 4) into methanol in a single step is a challenging issue for the utilization of CH 4. We present a direct method for converting CH 4 into methanol with high selectivity over a Pt/CeO 2 catalyst which contains ionic Pt 2+ species supported on a CeO 2 nanoparticle.

In this new effort, the researchers describe a simpler way to make methanol using water (as an oxidant instead of oxygen) and methane. In their process, water is used to oxidize methane over a bed...

A catalytic system containing Pt and Hg can oxidize methane to methyl bisulfate, but the methanol production from subsequent hydrolysis generates SO 2. Similarly, cationic Pt, Pd, and Au catalysts can oxidize methane with the use of strong oxidizing agents, such as selenic acid, producing environmentally unfriendly byproducts [ 10 , 11 ].
