production of energy materials

The present work aims to establish and solve a model to predict the dissolution of the coffee beans to know the best time
and concentration of solvent at room temperature. The mathematical model is based on the mass transport and chemical
reaction phenomena considering the option of core in shrinkage and solved by applying the technique of orthogonal placement.
The dissolution of more than 80% of the residual coffee grain in sulfuric acid at 60 ° C has been achieved. In order to make the
process green, tests have been carried out with green solvents at room temperature, preferably looking for the starch. This is
part of a research group project in which residual coffee grains are already used to remove heavy metals from wastewater. This
new branch of the project seeks to obtain residues that allow totally clean energy and no residue from the dissolution process.
The resolution of the model will allow to know the processes of dissolution, the distribution of products and predict the effect
in the operating conditions. Each species is represented by a mass balance in which species diffusion and dissolution kinetics
are included, the boundary conditions are: at the center of the particle the flow is zero and at the surface of the particle the
convection from the surface to the bulk. To represent the shrinkage of the grain is represented the decrease of the radius with
a total balance.
