- Аннотация: series of Ru-contained catalysts based on mesoporous and micro-mesoporous supports synthesized for the selective hydrogenation of naphthalene and tetralin in n-hexadecane solution. The influence of the support – HMS, SBA-15 and ZSM-5/MCM-41, namely porous structure and acidity on the catalysts activity were thoroughly investigated. It was found that the supports acidity has a diminutive effect on the cis-decalin formation due to increased isomerization activity of cis-decalin to trans-decalin. It was shown that the amount of unconverted tetralin influenced the final cis/trans decalines ratio considerably. The effect of parameters such as temperature, hydrogen pressure and reaction time on conversion and selectivity to partially or fully hydrogenated products was investigated under 3–7 MPa H2, 220–320 °C and 0.5–3 h. It provides a practically fully naphthalene conversion and a high cis-decalin selectivity.
