The goal is to find improvements of the lowearning coal to synthesis natural gas (CTSNG) process using the same raw material but producing a lowmargin, single synthesis natural gas (SNG) product. In the CTLNGM process, there are two innovative aspects.

Under current trends, production could rise to
WhatsApp: +86 18037808511Process Chemistry. Catalytic conversion of hydrogen (H 2) and carbon monoxide (CO) from coalderived syngas into methanol can be done with conventional gasphase processes, or with a liquid phase methanol (LPMEOH™) process developed by Air Products and Chemicals. The reactions of interest are: 2 H 2 + CO → CH 3 OH. CO 2 + 3 H 2 → CH 3 OH ...
WhatsApp: +86 18037808511Coal liquefaction is a process of converting coal into liquid hydrocarbons: liquid fuels and process is often known as "Coal to X" or "Carbon to X", where X can be many different hydrocarbonbased products. However, the most common process chain is "Coal to Liquid Fuels" (CTL).
WhatsApp: +86 18037808511In this paper, a methanol production process with high thermodynamic efficiency and a low production cost is presented. The proposed process is based on steam methane reforming, in which carbon dioxide (CO 2) captured from a power plant flue gas is employed to improve the stoichiometric number, methanol efficiency, and carbon efficiency and increase CO 2 conversion.
