Special Issue Information

Dear Colleagues,

This issue is a continuation of the previous successful Special Issues “New Catalysts and Reactors for the Synthesis or Conversion of Methanol”.

The scientific community widely considers global warming a major challenge to our society. The main cause of this critical issue is the increase in CO2 concentrations in the atmosphere due to the massive use of fossil fuels, which has only grown in recent years. Methanol is a versatile matter used both for industrial purposes and for various day-to-day life activities. As it exhibits high effectiveness as an energy carrier, renewable methanol has been proposed by Nobel Prize winner G. Olah as a means to close the CO2 loop. Methanol can be environmentally synthesized from any feedstock, and its reforming reaction does not alter the net CO2 emissions to the atmosphere.

One of the ways to address this problem is to use CO2 as a resource in the synthesis of valuable products, such as methanol, which can be obtained from CO2, and hydrogen provided from renewable energy (solar or wind power). In the industry, methanol synthesis using the catalyst CuO/ZnO/Al2O3 occurs at a high pressure (50 bar). This is, of course, very costly, and hence, one of the main aims of researchers is to find the right modifications to the traditional catalyst in order to make it work at a lower pressure while maintaining its high selectivity.

Methanol to hydrocarbon (MTH) is a promising process because it supplies a wide range of compounds as important intermediates in petrochemical synthesis, such as light olefins and high-quality gasoline. The conversion of methanol to hydrocarbons can be catalyzed by various catalysts (HZSM-5 for methanol to gasoline, SAPO-34 for methanol to olefines, etc.). The role of both catalysts and reactors in these reactions is very important, and the kinetic modeling of coke formation is necessary to reveal the effect of the coke content on the product distribution of the reaction and optimize the design and operation of the reactor.

In this Special Issue entitled “New Catalysts and Reactors for the Synthesis or Conversion of Methanol, 2nd Edition”, we welcome all kinds of works in the form of original research papers or short reviews that reflect the state-of-the-art of the research area dealing with methanol applications, based on new catalysts or reactors.

Dimethyl carbonate (DMC) is widely used as an intermediate and solvent in the organic chemical industry. In recent years, compared with the traditional DMC production methods (phosgene method, transesterification method), methanol oxidation carbonylation method, gas-phase methyl nitrite method, and the direct synthesis of CO2 and methanol method have made much progress in the synthesis process and development of catalysts. The key to the industrial application of DMC synthesis technology is the design and development of high-performance catalysts. Therefore, this paper reviews the research status of the methanol oxidative carbonylation method, gas-phase methyl nitrite method, and direct synthesis method of CO2 and methanol in the aspects of new catalyst design, catalyst preparation, and catalytic mechanism, and puts forward the problems to be solved and the future development direction of DMC catalysts.
