As a Formaldehyde Production Plant, let me share with you. There are many
reasons for the low methanol conversion rate in the silver formaldehyde process.
The main contents include problems in the process flow, the need to improve the
catalyst, low heat transfer efficiency, and poor air quality. Starting from
several aspects below, the reasons for the low methanol conversion rate in the
silver formaldehyde process are analyzed.
Formaldehyde Production Silver Process
The problem in the process flow is one of the reasons for the low methanol conversion rate in the silver formaldehyde process. Generally speaking, because the iron-molybdenum method produces formaldehyde process flow is more complicated, and it can be divided into silver method and iron-molybdenum method according to different catalysts according to the process of producing formaldehyde. In this process, the iron-molybdenum method usually has the characteristics of low reaction temperature, low unit consumption, high product concentration, high catalyst activity, etc. However, due to its low selectivity, average life, and high equipment production capacity requirements, the development of its process flow There are big problems. In addition, the problems of the process flow are also reflected in the low methanol conversion rate and the continuous occurrence of missing methanol in the conversion production operation of methanol. Therefore, it is very necessary to optimize the process flow.
"The need to improve the catalyst is also one of the factors that affect the low methanol conversion rate in the silver formaldehyde process. Generally speaking, the process of producing formaldehyde by iron-molybdenum oxidation method cannot do without the effective support of catalyst. That is, under the effective application of the catalyst, the process flow of methanol conversion can become more convenient and promote the efficiency of methanol conversion. In addition, the need to improve the catalyst is also reflected in the methanol conversion production process, where the vaporized methanol reacts after being mixed with air and circulating gas.
Therefore, in order to effectively avoid the uneven mixing caused by the thermally conductive catalyst, the staff should pay attention to reasonably avoid the occurrence of problems such as incorrect or less filling of the catalyst.
