The hydrocracking of 2,4-Xylenol (cas 105-67-9), chosen as a model compound for the hydropyrolysis of phenolic fractions was studied as a function of the following parameters: temperature, pressure, residence time and hydrogen partial pressure so as to determine the yield of light aromatic hydrocarbons (B T X) and the formation of light phenols (PC). These results, compared with those obtained by thermal pyrolysis, allow the determination of the experimental conditions under which the presence of hydrogen increases the yields of BTX, phenol and cresols instead of inducing the dehydroxylation of 2,4-xylenol. Under such conditions the amounts of solids and heavy liquid products are decreased. A postcracking temperature of 775 °C, a residence time less than 4 s, a total pressure of 1 MPa and a mole fraction of hydrogen of at least 0.25 lead to the highest yields of phenols and cresols; the yield of BTX increases with temperature, but is independent of pressure.
