Latest Patents

Uchida's latest patents include innovative methods and apparatuses for producing methanol. One of his patents describes a method that allows the temperature of the catalyst layer to fall within an appropriate range, thereby reducing energy consumption and achieving a higher carbon yield. This method involves a synthesis loop with at least two synthesis steps and two separation steps. It begins with obtaining a first mixed gas by mixing the final unreacted gas with a fraction of the make-up gas. Methanol is synthesized from this first mixed gas after preheating, followed by the separation of a first unreacted gas from the reaction mixture. The process continues with the final mixing of the unreacted gas and a fraction of the make-up gas, leading to further methanol synthesis and the separation of the final unreacted gas.

Another patent focuses on synthesizing methanol from a synthesis gas and separating unreacted gas from the reaction mixture. This method also features a synthesis loop with multiple synthesis and separation steps. It involves increasing the pressure of a residual gas through a circulator and mixing it with a fraction of the make-up gas to obtain a first mixed gas. The process includes synthesizing methanol, separating the first unreacted gas, and finally synthesizing methanol again before separating the final unreacted gas.
