  This paper is devoted to the analysis of a numerical scheme for the
coagulation and fragmentation equation with diffusion in space. A finite volume
scheme is developed, based on a conservative formulation of the space
nonhomogeneous coagulation-fragmentation model, it is shown that the scheme
preserves positivity, total volume and global steady states. Finally, several
numerical simulations are performed to investigate the long time behavior of
the solution.
