Exploiting the oxidizing capabilities of laccases exploiting the oxidizing capabilities of laccases for sustainable chemistry

Part one of this dissertation research has focused on harnessing the ability of laccases to generate reactive para-quinones in situ from the corresponding hydroquinones, followed by reaction with a variety of nucleophiles to perform novel carbon-carbon, carbon-nitrogen, and carbon-sulfur bond forming reactions for the synthesis of new and existing compounds. In part two of this dissertation, the fundamental laccase-catalyzed coupling chemistry developed in part one was applied to functionalize the surface of kraft lignin.

Prospects of hydrogen cogeneration and carbon dioxide utilization in electrochemical refineries for ethylene production via oxidative coupling of methane: A techno-economic assessment

Ethylene is recognized as one of the most significant chemicals globally. The projected ethylene production for 2023 stands at 227.6 million tonnes, with expectations of continued demand growth. The primary use of ethylene, accounting for over 76%, lies in the production of plastics such as polyethylene, polyvinyl chloride, and polystyrene. Despite the enduring carbon retention potential of plastics themselves, traditional ethylene feedstock production from fossil resources contributes substantially to greenhouse gas emissions, ranging from 0.29 to 2.29 kg CO2 /kg Ethylene depending on various factors like feedstock and process design. Various decarbonization strategies, including the utilization of hydrogen as a primary heat source, have been proposed to reduce the carbon footprint of ethylene production, but their efficacy remains limited, offering at best a 0–30% reduction in on-site CO 2 emissions.
