Simulating the pyrolysis of coal, after simulating it with a RYIELD reactor according to the literature, the display is as follows: Block: B3PYROLS Model: RYIELD * WARNING SPECIFIED YIELDS HAVE BEEN NORMALIZED BY A FACTOR OF (0.990100) TO MAINTAIN AN OVERALL MATERIAL BALANCE. * WARNING THE FOLLOWING ELEMENTS ARE NOT IN ATOM BALANCE: HNC
The yield of each substance has been adjusted but it still shows that the material is not conserved.
