Single-pass conversion rate of green methanol
Thread Content
Regarding the low-pressure synthesis of methanol: What is the current single-pass conversion rate for the hydrogenation of CO2 to produce methanol? What is the methanol selectivity? How many standard cubic meters of CO2 syngas are required to produce 1 kg of methanol? So, for a methanol production rate of 1 Kg/H, how much fresh gas is required? How much circulating gas is needed? How much catalyst loading is required? I humbly beg you! ! !
For low-pressure methanol synthesis, CO2 and H2 syngas is commonly used. The one-pass conversion rate of CO2 to methanol is typically between 5% and 10%, while the selectivity for methanol can reach as high as 90%–95%. Approximately 6–8 cubic meters of syngas are required to produce 1 kg of methanol. The specific requirements for fresh gas, recycle gas, and catalyst loading depend on the specific process design and operating conditions
Due to various constraints, the one-way conversion rate of CO2 may be low, typically ranging from a few percent to a little over ten percent. The selectivity for methanol can reach a very high level. The selectivity for methanol can exceed 90%, and even approach 100%.
In the Icelandic CRI, the one-pass conversion rate of carbon dioxide is approximately 22%, while the overall conversion rate is about 95%； The calculated selectivity to methanol is close to 100%. You can calculate the rest by yourself.
