Latest Patents

Kumon's latest patents include a "Catalyst for exhaust gas oxidation, method for producing same," and an "exhaust gas oxidation method using same." These patents describe a catalyst capable of effectively oxidizing exhaust gas, along with methods for preparing the catalyst and utilizing it in exhaust gas oxidation. The catalyst features a three-dimensional structure with at least two layers: a lower catalyst layer and an upper catalyst layer. Both layers independently contain precious metal and alumina and/or zeolite. Notably, part of the upper catalyst layer contains pores derived from a pore connecting agent with a combustion decomposition temperature between 300°C and less than 450°C.

Another significant patent is the "Diesel engine exhaust gas purification catalyst, production method therefor, and exhaust gas purification method using the same." This invention aims to provide a catalyst that effectively purifies exhaust gas, particularly targeting carbon monoxide (CO) emitted from diesel engines. The catalyst comprises precious metal and alumina and/or zeolite supported on a three-dimensional structure, featuring peaks for at least three different pore sizes in its pore size distribution.
