The role of clay purification in continuous reforming
Thread Content
I would like to ask fellow sailors: our factory has newly installed a 1 million-ton reforming unit. What is the purpose of clay purification? I heard that the white soil needs to be changed once a week? Is there a modified clay that can provide longer cycle life?
It is estimated that your reformer is equipped with a benzene extraction unit. White clay is refined to remove olefins from benzene. Using modified clay yields slightly better results, while using an olefin removal catalyst is quite effective.
There are deolefin catalysts whose efficiency and lifespan are much higher than those of clay
It seems that the Shanghai Chemical Research Institute and the Tianjin Chemical Research and Design Institute have products
Using the HDO post-hydrogenation catalyst from the Fuyan Research Institute for the selective hydrogenation of olefins yields the best results, providing a permanent solution. The deolefin catalyst is a molecular sieve; in my opinion, it provides only temporary relief rather than a permanent solution.
