Your work would have much more sense if you collaborate with experimentalists. They will feed you with the data and you do your job. I doubt that someone will be willing to confirm you simulation.

Tan Phat Nguyen, Without reliable information on the pyrolysis kinetics of the given biomass, the above-mentioned calculations are impossible. There are two ways: either you need to search for relevant data in the literature, or you have to carry out kinetic tests yourself, which is a very difficult task

Hello,

See the attached article for the typical gasification reactions.

Thanks for the advice of 2 PhD.

I think it will be difficult to find my biomass response kinetics because of the limitations of our facilities.

Badr A. Mohamed

Hello sir,

The article you provided had no information on the reaction kinetics. I am very confused about this

Thanks

Hi Tan Phat Nguyen

You mentioned that you are doing gasification simulation, and in that article you will find the heat required for the pyrolysis and endothermic reactions into the gasification zone.

Dear Badr A. Mohamed ,

I am simulating CFD and am having problems with pyrolysis kinetics.

I know the chemical reactions above.

Thank you for your enthusiasm

Tan Phat Nguyen

If you are looking for a detailed pyrolysis reaction kinetic model, the attached article may help you.

Badr A. Mohamed Thank you so much

I expected relevant data to be available in the literature. However, I am thinking about the equilibrium model. The lack of equilibrium constants is not a problem when using Aspen. But treating the oxidation of carbon and carbon monoxide as reversible is unacceptable to me. It is also not understood to analyze a linearly dependent system of chemical reactions. I also have doubts about the second publication, where only the reaction rate constants are given. Were all the reactions mentioned in the publication first-order?

I know how to use aspen and use the gibbs model to find chemical equilibrium coefficients. I expect the A and E coefficients of the Arrhenius equation for ease of use in Fluent

I agree with Mirosław Grzesik

Nobody would argue that you know how to use Aspen. It's standard now. However, the values of A and E are not enough, you still need to know the form of kinetic equations (rate laws).

By applying TG-TGD and if you may apply also DSC, better.

Of course, TG or DSC can be used, but the problem of describing the obtained kinetic curves remains. One can use the convolution method here, but it's a difficult task.
