I have a question about coal-to-oil for everyone!

In the literature, conversion rates and oil yields calculated using MAF -- a constant-humidity ash-free basis -- are occasionally seen. But what we commonly use is based on an anhydrous, ash-free basis. So I would like to ask: is there any conversion relationship between the constant-humidity ash-free base and the anhydrous ash-free base? For example, some formula or relationship? ? ? Thank you very much. This post was last edited by Zhenzhen Youci on 2009-4-1 at 14:24. Note: $ # $ $
Constant humidity refers to the moisture content of the coal sample (or its maximum intrinsic moisture) measured at a temperature of 30°C and a relative humidity of 96%. With this moisture data, the relationship between the constant-temperature ash-free basis and the dry ash-free basis data can be calculated.
