Description The main result is the description of all maximal delta 1-categories by means of alfa-pseudofilters. A delta 1 - category is a subcategory of the category of all semigroups possessing a divisor theory with less morphisms such that this divisor theory as a reflection. It is shown that these maximal delta 1- categories form a set with cardinal number equal to exp exp alef 0.
