What catalysts are generally used in gasoline hydrogenation reactors?

Once the reactor size is determined, the catalyst loading hardly changes, and thus the space velocity is also fixed

CNPC primarily uses a fixed-bed process, with catalysts that are produced through kneading and molding; Sinopec mainly employs the SZORB process, using microspherical catalysts

The original poster is asking about hydrogenation reactions; what do you mean by using S-Zorb for the desulfurization of gasoline through catalytic cracking?

Look at the question carefully by yourself: what kind of catalyst is generally used in gasoline hydrogenation reactors? S-ZORB is also used for gasoline hydrogenation – don’t you understand that?

Is S ZORB a hydrogenation reaction? As a well-known figure, you don’t even know this?

S-Zorb carries out the desulfurization of catalytically cracked gasoline using a desulfurizer containing zinc oxide; adsorption desulfurization is the main reaction. Although hydrogen is involved in the process, it is not used for hydrotreating purposes to carry out desulfurization. The S-zorb process was developed to desulfurize catalytic cracking gasoline without carrying out any substantial hydrogenation of the olefins. I’m not an expert, but I understand that the S-zorb process involves adsorption-based desulfurization rather than hydrogenation. Additionally, regarding the gasoline hydrogenation mentioned by the original poster, the S-zorb catalyst does not have any special functions; the hydrogenation conditions are there to maintain the activity for adsorption-based desulfurization, while its effect on saturating double bonds is minimal.

This answer is quite objective; I agree that the Szorb process is used for the adsorption and desulfurization of thiophene sulfur in gasoline, and the catalyst employed in this process is a microsphere catalyst with an average particle size of around 70 microns. Please add me on WeChat, lzy053900
