Direct Synthesis of Al-B-SBA-15 and Its Application in Preparing of Bifunctional Platinum Catalyst for Hydrogenation of Tetralin

Resumo

In this work, the mesoporous material Al-B-SBA-15 has been obtained by direct synthesis method with Si : B : Al ratio of 10 : 0.5 : 0.5. Wetness impregnation (WI) method was used to load platinum on Al-B-SBA-15. The prepared support and catalyst were characterized by nitrogen adsorption–desorption measurement (BET), XRD, TEM, and TPD-NH₃ to investigate the influence of boron and aluminium on characteristics of the catalyst. The activity of the bifunctional catalyst was tested for hydrogenation of tetralin at 180–220°C, hydrogen pressure of 1.5–2.5 MPa for 3 h.
