Selection of downstream products of methanol.

The downstream solid products of methanol mainly include formaldehyde, sodium methoxide, methanol protein, etc. Among them, products with good market prospects include formaldehyde, as it is widely used in the building materials and furniture industries. The common process routes for sodium methoxide include the direct synthesis method and the indirect synthesis method. The process package and route for methanol protein involve biological fermentation processes, and currently some companies in China are researching and developing production technologies for methanol protein. .

The solid products derived from methanol mainly include solid polymer products such as ethylene and propylene that may be produced during the process of converting methanol into olefins; however, these are not solids in their original form, but can become solids through further processing. Among the traditional downstream products of methanol, products such as formaldehyde and dimethyl ether, although primarily liquids, can assume a solid state under certain conditions or when used as components in certain products. Methanol downstream products with promising market prospects: Currently, methanol-to-olefins (MTO/MTP) represents one of the main drivers of demand for methanol downstream globally. In China, in particular, MTO is the largest application area for methanol, accounting for around 60% of China’s total methanol consumption. Methanol-to-olefins technology can produce low-carbon olefins such as ethylene and propylene. These olefins are important raw materials in the chemical industry, used in the production of various chemicals and polymers; therefore, the market prospects for this technology are promising. Process route for sodium methoxide: There are mainly two methods for preparing sodium methoxide: the hydration method – in which sodium hydroxide and methanol are heated to a certain temperature, resulting in the formation of sodium methoxide. Heating method: Methanol and sodium hydroxide are heated while an inert gas is introduced; this reaction produces sodium methoxide. Both methods require subsequent processes such as separation, refining, and purification of the reaction products to obtain sodium methoxide with a relatively high purity. The process package and route for methanol protein: Methanol protein is obtained by introducing specific genes into hosts such as Escherichia coli through genetic engineering techniques, and then utilizing the host’s metabolic mechanisms to synthesize proteins. The process mainly involves steps such as introducing genes into the host, culturing the host cells, protein synthesis, and isolation/purification. I’d also like to share a message posted on June 4, 2024, at 10:13: Recently, the world’s largest coal-based methanol monomer project – the 6 million tons per year coal-based methanol production facility owned by Qiyaxinjiang Group Co., Ltd. – was approved for construction. The project is located in the Jiangjunmiao Industrial Park within the Zhundong Economic and Technological Development Zone in Xinjiang, with a total investment exceeding 30 billion yuan.
