Catalyst for oxygen removal in olefins

It is applied in the synthesis of methane-rich gas with hydrocarbon (Light oil, naphtha, LPG, light hydrocarbon, hydrocarbon-containing dry gas etc.) and steam as raw materials. The resulted gas can be further used to produce hydrogen, syngas with different CO/H2 ratio (for the synthesis of methanol or ammonia etc.) and coal gas.

Product Details

The catalyst is for the selective removal of oxygen impurity with the existing H₂ in the olefins stream without the facilitating of the hydrogenation of olefins. It is mainly applied in the removal of O₂ in gas abundant of olefins obtained in the processes such as vacuum distillation, catalytic cracking, catalytic reforming, hydrocracking, residue cracking and so on, targeting to have the trace O₂ in level of below 1 ppm and make the olefin gas in polymer grade.

Comment:Catalyst A and B can be used by itself and jointly depending on different application scenario and O₂ level requirement. If they are used jointly, the O₂can be selectively reduced to below 0.1 ppm only at 150°C as an example.
