Thermal stability of aromatized feedstock at high temperature

Abstract

1. An investigation has been made of the behavior of an aromatized feedstock with a boiling point of 200–310°C with heating up to a temperature of 600°C at a high flow rate, under a hydrogen pressure of 40 atm in the presence of water vapor, and it has been shown that the feedstock does not undergo any considerable amount of conversion. 2. It has been established that, with heating of the feedstock up to 600°C, there is practically no formation of high-boiling hydrocarbons, and that the feedstock heat-exchange and heating system for the production of naphthalene can be operated continuously for a long period of time.
