The emission of greenhouse gases (GHGs) is a major air pollution issue that affects climate change across the globe. Methane (CH4), behind carbon dioxide (CO2), is the second most abundant GHGs that negatively impact the atmosphere layer. Many studies have been conducted to identify a method for reducing the concentration of methane in the atmosphere. Converting methane to alternative forms source of energy, such as methanol, is a preferred method for methane reduction. This review aims to present an overview of recent literature that focuses on conversion of methane to methanol, with a focus primarily on the manufacturing systems and processes used in this conversion. Basic descriptions are given of several relevant technologies for converting methane to methanol and their characteristics, including conventional catalytic processes, plasma technology, photo-catalysts, supercritical water processes, biological processes and other processes. All of these options are feasible for use in the conversion process of methane to methanol.
