Let’s discuss whether pre-conversion is necessary for hydrogen production from naphtha
Thread Content
The development of hydrogen production technologies in China is now quite mature. The process routes include light hydrocarbon steam reforming, methanol-to-hydrogen, coal-to-hydrogen, etc ； Hydrogen production feedstocks include natural gas, LPG, naphtha, methanol, etc ； The conversion formats include those with a pre-conversion reactor and those without one. Please discuss whether it is necessary to include a pre-conversion reactor when using straight naphtha as the feedstock for hydrogen production units (with a boiling range of 40–140°C). If such a reactor is not used, what consequences might arise? And if it is used, what considerations should be taken into account in terms of process design and operation? ； Also, are there any catalyst suppliers in the country whose conversion agents can meet the operational requirements of using this naphtha feed without pre-conversion? We invite all sailors and hydrogen production experts to participate in the discussion.
This should be brought, after all, it involves a certain level of difficulty in handling
Why is naphtha used as a raw material? Isn’t the cost high?
Naphtha, liquefied gas, and natural gas can all be used as raw materials for hydrogen production in our facility. We do not employ pre-conversion here, but the final boiling point of our naphtha must not exceed 100 degrees℃
For hydrogen production from dry gas in our company, the raw materials are supplied via a naphtha system as well as high-pressure propane lines. Recently, the management requested that we try using naphtha, and I would like to gather some information on this topic in order to assess the potential users
May I ask why the final distillation temperature for naphtha is required to be no higher than 100°C?
