Sažetak
A catalytic system has been examined in which, together with the chemical reaction, a deactivation reaction also takes place, reducing the active surface and thereby the main reaction rate. The study has established the balance for the main reaction and for the poisoning reaction. The adsorption (secondary reaction) is assumed to take place according to the Langmuir law by whose substitution in the balance the partial differential equation transforms into a form that can be solved. The differential equation for the main reaction balance is solved numerically by orthogonal collocation ; the partial equation for the secondary reaction is also solved by orthogonal collocation until reduced to an ordinary one and solved by the Runge-Kutta method. The software has been made in MathCad.
