The review considers the modern structure of methanol production and consumption. The main processes of methanol conversion and the catalysts for their implementation are reported: the production of formaldehyde, hydrocarbons (МТН) and olefins (МТО) as well as the generation of hydrogen from methanol by steam conversion, partial oxidation, autothermal reforming and decomposition.

In the present work, several parameters affecting on the catalytic behavior were studied in the process of partial oxidation of methanol to formaldehyde, such as: Mo/Fe ratio in unsupported catalysts, weight percent of the metallic phase in the supported catalysts, the effect of different supports, the method of Mo-Fe deposition on the supports, and the stability of the prepared catalysts against coke. These catalysts were characterized by X-ray diffraction (XRD), Fourier Transform Infra Red (FT-IR), Thermogravimetric Analysis (TGA), Scanning Electron Microscopy (SEM), N2 adsorption-desorption, and Atomic Adsorption Spectroscopy (AAS) methods. The best results (the methanol conversion = 97 % and formaldehyde selectivity = 96 %) were obtained for Mo-Fe/g-Al2O3 prepared by co-precipitation method with Mo/Fe = 1.7, 50 wt.% of Fe-Mo phase, 2 mL/h methanol flow rate, and 120 mL/min air flow rate at 350 oC.

Abstract: A growing interest in hydrogen use has been observed due to its environmentally friendlycharacteristics. However, the current methods of hydrogen production from natural gas are based on steammethane reforming, partial oxidation, and autothermal reforming. These processes produce a mixture ofhydrogen and carbon oxides and after water-gas shift reactions, in order to increase the production ofhydrogen, a large amount of CO2 is generated and possibly released in the atmosphere. In this context, thecatalytic methane decomposition has been receiving attention as an alternative route to the production ofCOx-free hydrogen. It has been reported that the appropriate group of catalysts and reactors can lead to aviable process. Current investigations attempt to increase the yield of hydrogen. The present work aims toevaluate the processes currently used for that and to present the preliminary results obtained with cobaltcatalysts for methane decomposition. A comparison between the conventional processes and the suggestedones is made, and the major advantages in the use of methane decomposition are presented.

The promoter ZrO2 was applied to prevent Cu crystallites from sintering over CZ (ca. Cu 30 wt.% and Zn 70 wt.%) under partial oxidation of the methanol (POM) reaction. Gold was selected to promote the performance of CZrZ (ca. Cu 31 wt.%, Zr 16 wt.%, and Zn 53 wt.%) catalyst to overcome a high ignition temperature of 175 °C and CO selectivity (SCO) (>10% at T. > 200 °C). Experimentally, the deactivation rate constant of A5CZrZ (ca. Au 5 wt.%, Cu 31 wt.%, Zr 17 wt.%, and Zn 47 wt.%) and CZrZ was 1.7 times better than A5CZ (ca. Au 5 wt.%, Cu 31 wt.%, and Zn 64 wt.%) and CZ. The methanol conversion of CZrZ and A5CZrZ catalysts was kept higher than 70% for 12 h in an accelerated aging process. Meanwhile, the Au prompted more methoxy species oxidizing to formate on Cu+-rich A5CZrZ surface at lower temperature, and also improved CO transfer from formate reacting with moveable oxygen to form CO2. The SCO can lower to ca. 6% at 200 °C after adding 3–5% of gold promoter. These features all prove that the CZ catalyst with ZrO2 and Au promoters could enhance catalytic activity, lower the SCO and ignition temperature, and maintain good durability in the POM reaction.
