Solar Thermochemical Green Fuels Production: A Review of Biomass Pyro-Gasification, Solar Reactor Concepts and Modelling Methods

Résumé

This paper addresses the solar thermochemical conversion of biomass or waste feedstocksbased on pyro-gasification for the clean production of high-value and energy-intensive fuels. Theutilization of solar energy for supplying the required process heat is attractive to lower the de-pendence of gasification processes on conventional energy resources and to reduce emissions ofCO2and other pollutants for the production of high-value chemical synthetic fuels (syngas). Usingconcentrated solar energy to drive the endothermal reactions further allows producing more syngaswith a higher gas quality, since it has not been contaminated by combustion products, while savingbiomass resources. The solar-driven process is thus a sustainable and promising alternative route,enabling syngas yield enhancement and CO2mitigation, thereby potentially outperforming theperformance of conventional processes for syngas production. This review presents relevant researchstudies in the field and provides the scientific/technical knowledge and background necessary toaddress the different aspects of the solar gasification process. An overview of the available solarconcentrating technologies and their performance metrics is first introduced. The solar gasifier con-cepts and designs that were studied from lab to industrial scale are presented, along with their mainbenefits and limitations. The different management strategies proposed to deal with solar energyvariations are also outlined, as well as the major pilot-scale applications and large-scale system levelsimulations. A specific emphasis is provided on the spouted bed technology that appears promising for the gasification process. Finally, the main modeling approaches of pyro-gasification and kinetics for simulation of gasifiers are described. This study thus provides a detailed overview of the efforts made to enhance the thermochemical performance of solar-assisted biomass gasification for synthetic fuel production
