Palladium on Alumina

‌Palladium on Alumina‌ is a catalyst made of a mixture of aluminum oxide and metallic palladium, which has good catalytic activity and stability. Its chemical formula is Pd/Al₂O₃, and its CAS number is 7440-05-3‌12. The preparation of palladium on alumina catalyst usually involves impregnating a palladium salt solution on an alumina carrier, and then fixing the palladium through steps such as drying and calcination. This process can adjust the performance of the catalyst by controlling the content of palladium and aluminum‌3.

Application areas:

Palladium on alumina catalysts are widely used in a variety of chemical reactions, including:

‌Hydrogenation reaction‌: used for hydrogenation reactions of aromatic aldehydes, aniline and its derivatives, nitroaromatics, and aliphatic compounds‌.

‌Industrial tail gas purification‌: used for the purification of pure gases‌.

‌Hydrogen peroxide production‌: used in the production process of hydrogen peroxide‌.

‌Deoxygenation catalyst‌: used for the deoxygenation of inert gases such as hydrogen, argon, and nitrogen, deoxygenation at room temperature, no regeneration required, long service life, and high catalytic activity‌.

Performance characteristics:

‌High catalytic activity‌: It can effectively catalyze reactions at low temperatures.

‌Good stability and selectivity‌: It can work stably at high temperatures and effectively suppress the toxicity of the reaction‌3.

‌High selectivity‌: It can reduce the toxicity of the reaction products‌.
