The values of characteristics, R and M, for MeOH synthesis
19 August, 2017 by Namlo Nahtem
As in the  description of the characteristics defined for the feedstock composition of syngas to methanol synthesis reactor, two types of the characteristics value are exsiting. One is usually used as R by JM/Davy and TOYO or as SN by Air Liquide or as Module  by Haldor Topsoe, and the other is used as M by Mitsubishi Gas Chemical.  I am afraid some people misunderstand  that R, SN and Module are equal to just two times M, but are more than two times depending upon the moler ratio of [CO2]/[CO] with which R increases correspondingly much more than two times M if the molar ratio increases.   See the figure below.

The relationship R and M is derived as follows.
