Abstract
Solid catalysts for petroleum refining and catalytic transformations have been developed starting from local Algerian materials, mainly “bentonite“[1]. These catalysts are used for the transformation of the heavy fractions and the residues of the oil by the catalytic processes leading to obtaining clean and environmentally friendly petrol (fuel) as well as petroleum fractions that are considered as important raw materials for petrochemical, pharmaceutical, and cosmetic industry. The preparation of modified catalysts using Algerian local bentonite enriched by oxides to give them a better performance for the validation of certain fractions of oil and condensate is described. Keywords: Heterogeneous catalysis; Heavy petroleum fractions; Solid Catalysts.
