AI Technical Summary
Technical Problem
When existing deoxygenation catalysts treat petrochemical dry gas with high hydrogen content, they have poor selectivity, which can easily cause the reactor catalyst bed fly temperature, and are costly and have poor stability.
Method used
The deoxygenation catalyst including metal Cu and metal Ni as active components, alumina, activated carbon, silicon oxide or alumina-silicon oxide composite support is obtained by impregnation or spraying, and dried and calcined.
Benefits of technology
The catalyst exhibits good deoxygenation selectivity and stability under high hydrogen content conditions, avoids reactor fly temperature, reduces production costs, and improves the purification efficiency and recovery rate of olefins.
