Preparation method and optimization method of carbon monoxide catalyst

Carbon monoxide catalyst is a common catalyst used to treat carbon monoxide produced by incomplete combustion of combustible gas. Carbon monoxide catalyst is divided into precious metal and non-precious metal.
The preparation method of carbon monoxide catalyst is divided into physical method and chemical method. The catalyst prepared by physical method is obtained by obtaining impurities in compressed air through multiple treatments and screening, and the quality is not very stable. Therefore, physical preparation method is generally not selected to make carbon monoxide catalyst. The commonly used method is chemical method.
The preparation methods of carbon monoxide catalysts mainly include precipitation method, impregnation method, coprecipitation method, etc. Among them, coprecipitation method is a more commonly used method. First, add ligands to the mixed solution, stir at room temperature, and then slowly add metal ion solution. During the reaction, pay attention to controlling the temperature and pH value, so that a better catalyst can be made.
The optimization methods of carbon monoxide catalysts mainly include the following points: improving the dispersion of the catalyst, increasing the specific surface area of the catalyst, optimizing the catalytic reaction conditions, etc. Among them, improving the dispersion of the catalyst is a very critical step, which can achieve better dispersion effect through carrier-metal interaction enhancement, nano-space confinement and precise control of the kinetic process. Increasing the specific surface area of the catalyst can be achieved by increasing the pH value of the solution after the catalyst is reduced. Optimizing the catalytic reaction conditions can improve the catalytic reaction effect by controlling the reaction temperature, gas flow rate, reaction time, etc.

In short, the preparation and optimization of carbon monoxide catalysts are of great help to improving product efficiency, and will also achieve good results in the treatment of industrial waste gas. Carbon monoxide catalysts have realized their value in the fields of waste gas generated by industrial enterprises, and it is also hoped that scientific research and development and technology will achieve greater achievements in the coming days.
