Original abstract
Gasification of lignocellulosic biomass is now seen as a good way to produce renewable syngas, hydrogen, and valuable chemicals, while also helping with carbon neutrality and sustainable energy. However, problems like low efficiency, catalyst deactivation, tar formation, and limited process integration still stop it from being used on a large scale. This review gives an overview of recent progress in catalytic gasification of lignocellulosic biomass from the angles of reaction mechanisms, making catalysts, process strengthening, and combining systems. First, basic routes of tar cracking and methane reforming are summarized to show their roles in syngas upgrading and hydrogen production. Then, catalytic performance, deactivation behavior, and modification methods for natural minerals, alkali and alkaline earth metals, nickel catalysts, two-metal systems, and new support materials are discussed. Recent progress in process optimization, such as biomass chemical looping gasification, co-gasifying coal and biomass, microwave-assisted gasification, and adjusting operating conditions, is reviewed, with focus on improving syngas quality, carbon conversion, and energy efficiency. Moreover, advances in combined gasification systems that make heat and electricity together, hydrogen, and chemicals are looked at, noting their potential for being carbon-negative and producing several products. Finally, remaining technical problems about catalyst stability, process cost, feedstock variability, and industrial scale-up are pointed out, and future study on better catalyst design, linking processes, digital optimization, and combined energy systems is suggested. This review offers a systematic reference for developing and commercializing high-efficiency catalytic biomass gasification technologies.
