In a biomass pyrolysis process, 1 0 5 0 k g of wood chips containing 4 6 % moisture ( by weight ) is fed
In a biomass pyrolysis process, of wood chips containing moisture by weight is fed into sequential processes. Initially, all of the moisture content was removed in a dryer at
In the second step, a reactor for pyrolysis is used. The pyrolysis reaction produces three main products: biochar, biooil, and offgas. The composition of these products is as follows: Biochar: of the feedstock mass; Biooil: of the feedstock mass; Off gas: the remaining feedstock mass.
The onethird of the Biochar is used as fertilizer in agricultural applications. The remaining part is sent to a furnace for the graphitization process, which is conducted at for hours under an Argon atmosphere. It is known that the yield of the final process is
Using the information above,
