How to determine the amount of catalyst used in the catalytic cracking of tar produced in biomass carbonization projects?
Thread Content
For example, to catalytically crack biomass tar, how to determine the amount of catalyst used? A lot of literature is not available, only the introduction of temperature and contact time, experts can provide it, thank you very much!
It seems that the use of catalysts to crack tar is only a laboratory achievement and has no practicality. So it cannot be linked to usage
Then the laboratory should also have a quantitative method, right? On what basis does the laboratory determine the amount of catalyst?
The amount of catalyst should depend on the size of the reaction vessel and the properties of the catalyst, similar to the particle size. But this may be different from ordinary chemical reactions. My own understanding is to set the time for the gas to pass through the reactor. Of course, the flow rate of the gas, the nature of the catalyst and the volume of the reactor are known. Passing the catalyst will definitely slow down the speed of the gas, and the gas must pass within the specified time. Then we can calculate how much catalyst should be placed in the reaction vessel.
