Polyethylene glycol (PEG) is not satisfactory for the removal performance of thiophenic sulfurs, e.g., low S-partition coefficient KN (S). The unsatisfactory KN may be due to relatively low content of active O atom on PEG. Modification replacing –OH group with –OCH3 group can produce modified PEGs that have the higher active O-content. Polyethylene glycol dimethyl ether, which was commonly known as...
A tailor-made encapsulated catalyst with SAPO-34 zeolite shell has been synthesized over Fe3C nanoparticles to form a core-shell structure via surface modification of Si-OH groups. The core-shell structure catalyst Fe/C@Si-SAPO are investigated via Fischer-Tropsch synthesis to evaluate their catalytic performance on the direct synthesis of light olefins from syngas. In comparison with the simple mixing...
