Electrophilic reactions at single bonds. 20. Selective monohalogenation of methane over supported acidic or platinum metal catalysts and hydrolysis of methyl halides over .gamma.-alumina-supported metal oxide/hydroxide catalysts. A feasible path for the oxidative conversion of methane into methyl alcohol/dimethyl ether

Structure and phase analysis of one-pot hydrothermally synthesized FePO4-SBA-15 as an extremely stable catalyst for harsh oxy-bromination of methane

“…Photochemical or thermal halogenation of hydrocarbon with halogen is known as a free radical chain process and lacks selectivity. Many interesting works [1][2][3][4] have been carried out to improve the selectivity of methyl halide. However, halogens are highly corrosive to equipment and dangerous to handle which present a big trouble for the industrialization.…”

New route for light olefins production from chloromethane over HSAPO-34 molecular sieve

“…Some promising results appeared to be of great importance in the field of catalytic conversion of chloromethane to higher hydrocarbons. In 1985, Olah et al described a very interesting three-steps catalysis process for the transformation of methane to higher hydrocarbons through monohalogenation of methane, hydrolysis of halide methane to methanol, and then the MTG reaction on HZSM-5 [1]. In 1988, Taylor et al invented a cyclic process for the production of gasoline from methane with chloromethane as the intermediate [2,3] and the transformation was reduced to two stages, i.e.…”

Demonstration of CO2 Conversion to Synthetic Transport Fuel at Flue Gas Concentrations

“…With CDU processes in mind, the two obvious candidates for the starting hydrocarbon and alcohol shown in Figure 3 would be methane and methanol, both readily synthesized by the hydrogenation of CO2 (Figure 4) (Mikkelsen et al, 2010;Saeidi et al, 2014). The selective formation of methyl halide from the reaction of methane and the elemental halogen is somewhat challenging, due to the higher reactivity of the products than starting materials, although appropriate choice of rare-earth or precious metal catalyst can yield the desired product (Olah et al, 1985;Podkolzin et al, 2007). By comparison, the conversion of methanol into any of the methyl halides is rather trivial using the hydrogen halide to carry out nucleophilic substitution.…”
