Abstract: The study elucidates the effect exerted by the composition of alumina support with the addition of milled aluminum hydroxide/oxide residues on its textural and strength characteristics and catalytic properties of Pt, Re-containing systems with these supports in nheptane reforming. The introduction of milled dried residues was shown to increase the support strength. The content of residues in the catalyst can be increased up 100 wt.% without a detrimental effect on the target characteristics of the catalyst performance in reforming. According to experimental data, a high (from 50 to 100 wt.%) content of such residues in the support increases the mechanical strength factor of the support to 30 abs.%, which may be related to remodification of the aluminum hydroxide structure during its “resynthesis”. It was demonstrated that 1-2 wt.% of milled residues of the calcined support can be used in the synthesis because this amount only slightly changes the mechanical strength factor and does not affect the catalyst performance. This approach is based on dilution of the initial pseudoboehmite with calcined Al2O3 at the peptization step.
