High methanol content at the bottom of the wash tower in methanol-to-hydrogen process
Thread Content
The methanol content at the bottom of the wash tower in the methanol-to-hydrogen process is high. The Shutai hydrogen production catalysts have been replaced after 3 years of use; previously, the methanol level was kept below 3%, but since operations resumed in October this year, it has remained high. How can this be adjusted?
Currently, the methanol content in the water at the bottom of the wash tower for hydrogen production from methanol is between 7% and 10%
The conversion rate is insufficient; reduce the amount of methanol used
Correct: victory:
The conversion rate is insufficient; reduce the amount of methanol used! For example: the original ratio of desalinated water to methanol was 1:1, but now 0.6-0.8 is sufficient.
It has been in use for three years, and it is now nearing the end of its catalyst life. There are two approaches: one is to increase the water content and reduce the methanol concentration； II. Raise the temperature of the heat transfer oil
Dalian Rick Technology Co., Ltd. is the project implementation unit for the industrialization of the Catalysis R&D Center affiliated with the Dalian Institute of Chemical Physics, Chinese Academy of Sciences. It possesses the largest coal chemical catalyst production base in the country, as well as a laboratory that has been approved by the National Development and Reform Commission. Catalysts for hydrogen production via methanol cracking offer advantages such as high conversion efficiency, good selectivity, and long service life.

We have used Shute’s catalyst several times; this year we switched to a catalyst from another company. The reaction temperature is 340, and the methanol content in the wash tower is below 1%
Increasing the alcohol-to-water ratio or the reaction temperature will both lead to higher energy consumption
Where is Shutai? ? How effective is it?
Reaction temperature 340°C? It’s 240°C, right? By the way, may I ask which manufacturer’s catalyst was used?
