Hi all, I am facing a bit of a trouble when inserting the kinetic rate for my chemical reactions, i would like to introduce a kinetic rate dependent on T (kT^nexp(Ea/RT)). When i use the 'user defined option', instead of the basic introduction of k and Ea, it always gives a syntaxis error. I am quite sure it is a little mistake or something that i am not aware, but i couldn't see it yet and i would be thankful if someone could finally spot the error. Attached you can find the file (Brouwer's reactions)....

Thank you! I will play around with it now! :-)

Hi, Thank you for your prompt reply. I changed to Raoult's law PP and checked Mixture was chosen as reacting phase. All reactions were Miixture, not sure if i have to say it also in the block for the reactor somewhere. In any case, no differences shown. Is it a chance that kinetic reactions as those described do not support solids as reacting phase even though Mixture has been set? Regards, Cristina

Hi, I would like to simulate the gasification of biomass using DWSIM but i encountered some problems when implementing the model. I am new with the software so i'm pretty sure the settings are not completely correct... biomass is defined by its elemental components, there is a block creating the tar components, then a mixer to introduce air into the system (not sure why the temperature at the outlet is 2900C, mass balance seems to work well though) and then oxidation and reduction reactions take...
