Abstract: The effect an oxygen-containing compound has on the cracking of an aromatic hydrocarbon is studied using the example of a model mixture of phenol-tetralin. An analysis of the temperature dependences of the cracking rate constant of tetralin and tetralin in a mixture with phenol indicates inhibition of the cracking of tetralin during its co-conversion with an oxygen-containing compound, due to the greater adsorption capacity of phenol on the catalyst’s surface. It is found that phenol in the model mixture alters the composition of liquid products, especially at low cracking temperatures. The effect water on the conversion of a phenol-tetralin mixture is studied. It is established that water in the model feed reduces the inhibition of the cracking reaction of an aromatic hydrocarbon by an oxygen-containing compound. Based on results from catalytic transformations, it is determined that when water is added, the level of the overall conversion of the mixture and the conversion of tetralin increase regardless of temperature. No appreciable qualitative differences between the distributions of cracking products in model mixtures with and without water.
