Model development for real oxygen delignification processes
Previous extensive work has been done on modeling the oxygen delignification process, based on how the basic parameters, i.e., temperature, kappa number, concentration of alkali, and concentration of oxygen, affect the delignification rate. However, these models are not used extensively to evaluate the performance of real processes, primarily because ...

Manufacturing process and mechanical testing of lignin polymer composites. ABSTRACT Lignin is a plant‐derived, the second most abundant natural polymer, and a waste byproduct of the pulp industry. Incorporation of lignin into plastic composites using scalable approaches is commercially favored and low carbon‐cost.

A colloid‐mediated electroless plating (CMEP) strategy is proposed to fabricate hierarchically porous, amorphous Fe‐doped NiWB electrocatalysts under ambient conditions. The in situ formation of Fe‐W‐O colloidal species guides the formation of robust, porous catalyst layers with excellent mass transfer and durability, sustaining 500 mA cm−2 for 2000 h,

Sustainable Porous Carbon Derived from Lignin for High‐Performance CO2 Capture
Lignin‐derived porous carbons offer a sustainable and scalable route for high‐performance CO2 capture. By tailoring ultramicroporosity, hierarchical pore networks, and heteroatom functionalities through chemical activation, templating, and hybrid methods, adsorption capacity and selectivity can be optimized. This review correlates.

Hydrothermal and Solvothermal Synthesis of Cerium-Zirconium Oxides for Catalyst Applications
Cerium oxide (CeO2) is a rare earth metal oxide that has high oxygen storage capacity at low temperature. In order to enhance this capacity, as well as its thermal stability, it is necessary to combine CeO2 with zirconium oxide (ZrO2).
