Direct dimethyl carbonate synthesis from CO and methanol over a flower-like CeO catalyst with 2-cyanopyridine as a dehydrating agent in continuous packed-bed reactor.

A flower-like CeO catalyst was successfully synthesized using an acrylamide graft copolymerized on glucose under hydrothermal conditions and used for the direct synthesis of dimethyl carbonate (DMC) from CO and CHOH in a packed-bed reactor with 2-cyanopyridine as a dehydrating agent. The synthesized flower-like CeO exhibited both basicity and acidity properties with values of 300 μmol g and 80 μmol g, respectively, according to CO-TPD and NH-TPD results. The effect of reaction parameters such as reaction temperature, feed ratio, catalyst quantity, and operating pressure on the DMC production over the flower-like CeO catalyst was investigated.

Tar steam reforming for synthesis gas production over Ni-based on ceria/zirconia and LaSrCoFeO in a packed-bed reactor.

In this work, NiO level was varied from 5 to 40% whereas CeZrO (x = 0.5, 0.7 and 0.
