Facile Preparation and Promising Hydrothermal Stability of Spherical γ-Alumina Support with High Specific Surface Area

It is of great importance to develop a spherical γ-alumina support with high hydrothermal stability be used in platinum reforming catalyst processes. The porous pseudo-boehmite powder surface area was first synthesized via simple separate nucleation and aging steps method, then as precursor produce γ-Al2O3 an oil–ammonia column method. as-synthesized has substantially greater specific 336.0 m2·g−1 comparison the commercial Sasol boehmite (293.0 m2·g−1) from Chemicals. In addition, as-prepared derived also possesses higher 280.0 compared corresponding sample. Moreover, balls demonstrate much 185.0 sample 142.0 after tests at 600 °C, suggesting its promising application chemical industry.
