We propose an exchange economy evolutionary model with discrete time, in which there are two utility-maximizing groups of agents which differ in the preference structure.Assuming an evolutionary mechanism based on the relative utility values realized by the two kinds of agents, we analytically and numerically investigate the existence of equilibria

In petroleum refineries, naphtha reforming units produce reformate streams and as a by-product, hydrogen (H2).Naphtha reforming units traditionally deployed are designed as packed bed reactors (PBR).However, they are restrained by a high-pressure drop, diffusion limitations in the catalyst, and radial and axial gradients of temperature and concentr
