Hydrotreatment
The hydrotreatment of middle distillates is an important process in the petrochemical industry [1]. Typically, the hydrotreatment reactions are catalyzed by Co(Ni)Mo(W) catalysts supported on alumina [2]. The origin of the almost exclusive use of alumina as support has been ascribed to its outstanding textural and mechanical properties and its relatively low cost [3]. However, the evidence of undesirable strong metal-support interaction has urged numerous studies devoted to new supports [3]. Recently, the use of mesoporous silica materials as SBA-16 for supporting CoMo, NiMo and trimetallic NiMoW as active phase in hydrodesulphurization (HDS) processes are intensively studied [4]. The advantages of mesoporous materials include high surface-to-volume ratio, variable framework compositions and high thermal stability.
