Thoughts on the production of iron-molybdenum formaldehyde

Thread Content

The author was fortunate to be involved in the development of three sets of iron-molybdenum-formaldehyde equipment. The design differences between these three sets were not significant; some of the technologies used were foreign, while others were domestic. The domestic technologies followed the approach employed in the past with the silver method, involving in-depth study of foreign technologies in order to build on their strengths and address their weaknesses, resulting in solutions that had distinct domestic characteristics. These solutions had both advantages and disadvantages, and some of the instrumentation devices could be eliminated to further reduce costs. Perhaps, out of conservatism, domestic technicians have added many instruments to the design of the entire system that are not very useful; however, they are still beneficial for production as they can serve as reference data. Some aspects of the design need further optimization, and of course, there are also issues with other selection choices that require improvement. At present, the entire installation is operating smoothly, with all controls being automated – there is no difference in this regard compared to foreign technologies. Before starting up, a conservative approach was adopted, and many parameters were controlled manually; however, once stable production was achieved, all controls became automatic. Based on current operations, the specific consumption is between 426 and 428, while the conversion rate is around 94%. However, the carbon monoxide level is slightly high; this requires further optimization by adjusting the reaction temperature to an appropriate value. Having been involved in the production and operation of iron-molybdenum formaldehyde over the years, the main challenge in this process is determining the optimal reaction temperature in order to maximize the value of the catalyst. In short, it seems that domestic technology has now reached international standards, but further efforts are still needed by domestic experts in the field of catalysts.
