Abstract: The paper first obtains the L2-apriori estimates for the solutions of two kinds of autocatalytic models under Dirichlet boundary conditions, and then, using the properties of linear semigroup and delicate calculations, the estimates of the maximal norms are obtained, therefore, the global existence of the solutions is proved. In the meantime, the existence of the maximal attractor is also given.

Key words: autocatalytic model, global solution, linear semigroup, maximal attractor
