According to the abstract released by the Intellectual Property India: "The present disclosure relates to a method and a system for the preparation of methanol from coal. The method comprises receiving coal, superheated steam, and oxygen to generate a syngas. The syngas is processed in a cooler system for removing fly ash present in the syngas through cyclone and dust filter, followed by removing impurities to produce partially cleaned syngas. The partially cleaned syngas is reacted with a steam and a catalyst followed by amine treatment to obtain a partially purified syngas which are then compressed and fed to the methanol synthesis unit to convert into methanol. The method of the present disclosure improves conversion efficiency of coal to methanol and can be able to handle different sizes of coal with different ash content. The system of the present disclosure is easy to operate and environment-friendly."
