“…Precious metals are obviously ideal as active catalysts for the DRM, but they are outrageously costly and scarce; therefore, substituting them with more economically affordable ones is unavoidable. [9][10][11][12] Nickel is the most commonly used active metal in CO 2 -CH 4 reforming catalysts due to its high intrinsic activity, availability, and inexpensive cost compared to precious metals and fairly notable catalytic behaviour. However, they suffer severe coking and subsequently deactivation due to harsh tuning operating conditions, catalyst preparation techniques, poor homogenous metal-support interface interactions, inaccurate metal oxide promotion, and a low surface carbon oxidation rate among others.…”

With an aromatic structure, lignin has great potential for the production of high value-added chemicals. In this study, Co/m-ATP catalyst was prepared by the co-impregnation method to depolymerize lignin with inexpensive attapulgite as a carrier, 1,4-dioxane as a solvent, and ethanol as an in situ hydrogen source. Meanwhile, formaldehyde stabilization facilitates lignin monomer production during biomass depolymerization. The effects of Co particle loading and reaction conditions (e.g., temperature and reaction time) on lignin conversion and product yield were investigated, resulting in a low char yield (6.6 wt %) and high bio-oil yield (63.1 wt %) when alkali lignin was depolymerized over the Co/m-ATP catalyst (cobalt loading of 15 wt %) at 220 °C for 8 h. Therefore, this catalyst with the advantage of low cost and high catalytic activity would be a potential catalyst during the depolymerization of lignin.

“…In order to solve the problem of crude glycerol utilization, scientists have explored and developed different synthetic procedures to convert GL into high value-added derivatives, such as the steam reforming of glycerol [3][4][5][6][7], catalytic esterification of glycerol, catalytic hydrogenolysis of glycerol and among others. Among various GL derivatives, glycerol carbonate (4-hydroxymethyl-1,3-dioxolane-2-one, GC) has the advantages of low flammability, low toxicity, high boiling point, and biodegradability [8].…”

A series of Mg-Zr composite oxide catalysts prepared by the hydrothermal process were used for the transesterification of glycerol (GL) with dimethyl carbonate (DMC) to produce glycerol carbonate (GC). The effects of the preparation method (co-precipitation, hydrothermal process) and Mg/Zr ratio on the catalytic performance were systematically investigated, and the deactivation of the catalyst was also explored. The Mg-Zr composite oxide catalysts were characterized by XRD, TEM, TPD, N2 adsorption-desorption, and XPS. The characterization results showed that compared with the co-precipitation process, the catalyst prepared by the hydrothermal process has a larger specific surface area, smaller grain size, and higher dispersion. Mg1Zr2-HT catalyst calcined at 600 °C in a nitrogen atmosphere exhibited the best catalytic performance. Under the conditions of reaction time of 90 min, reaction temperature of 90 °C, catalyst dosage of 3 wt% of GL, and GL/DMC molar ratio of 1/5, the GL conversion was 99% with 96.1% GC selectivity, and the yield of GC was 74.5% when it was reused for the fourth time.
