Today, the presence of heterogeneous catalysts in the chemical industry is very extensive and highlighted. The development of technical knowledge of new catalysts to increase the efficiency of industrial units has become the most important competition among the owners of technical knowledge of chemical processes[1]. The catalyst is a chemical solid with an optimal chemical composition for a chemical reaction and contains a structure appropriate to the properties of the physical chemistry suitable for the industrial process. The type and geometry of the industrial reactor is important for the design of the catalyst structure, which is why the reactor and the catalyst are two components that are completely interconnected [2]. The introduction of various chemical challenges, heat and mass transfer, mechanical strength, reactor filling and discharge procedure, contact time with reactor feed, etc., have made the catalyst an interdisciplinary science requiring a wide range of expertise in surface and solid chemistry, chemical engineering , ceramic materials, mechanics and solid state physics. Among them, the role of chemistry as a path initiator is very high. In this paper, the role of solid and solid chemistry on the development of technical knowledge of heterogeneous catalysts has been considered on the basis of refinery catalytic processes [3].
