The escalating challenges of environmental pollution and energy depletion have underscored the urgent need for renewable and sustainable biofuels as viable alternatives to traditional fossil fuels. The increasing global demand for nonrenewable fossil fuels is driven by the challenges of rapid population growth and accelerating economic development. As nations strive to sustain expanding industries and urbanization, the reliance on finite energy resources continues to pose significant environmental and economic challenges, necessitating urgent exploration of sustainable alternatives. The conversion of abundantly available biomass into biofuels is attracting significant attention, and it is seen as an innovative technique for addressing environmental problems and attaining net-zero carbon emissions involves balancing carbon output with removal strategies, ensuring that anthropogenic CO2 emissions are fully offset through carbon sequestration, renewable energy adoption, and advanced mitigation technologies. The utilization of a wide range of raw materials as feedstock for biofuel production is dependent on factors such as biomass availability, cost-effectiveness, and geographic location. Lignocellulosic (LC) biomass has received significant attention from researchers worldwide due to its diverse range of basic components, and it is suitable for second-generation biofuel production. This chapter presents an in-depth exploration of the fundamental principles and advanced applications of thermochemical and biochemical conversion processes. It explores thermochemical processes such as pyrolysis, torrefaction, hydrothermal liquefaction, and gasification, along with biochemical approaches, including pretreatment methods, enzymatic breakdown, and microbial conversion techniques. The discussion integrates process efficiencies, reaction mechanisms, and technological advancements, offering a comprehensive perspective on biomass valorization. These processes play a pivotal role in the biomass biorefinery of lignocellulosic materials and offer substantial potential for biofuel production. The technical aspects of lignocellulosic biofuel production are examined, with a focus on distinct processing strategies, including separate hydrolysis and fermentation (SHF), simultaneous saccharification and fermentation (SSF), simultaneous saccharification and co-fermentation (SSCF), and integrated consolidated bioprocessing (CBP).

摘要

The escalating challenges of environmental pollution and energy depletion have underscored the urgent need for renewable and sustainable biofuels as viable alternatives to traditional fossil fuels. The increasing global demand for nonrenewable fossil fuels is driven by the challenges of rapid population growth and accelerating economic development. As nations strive to sustain expanding industries and urbanization, the reliance on finite energy resources continues to pose significant environmental and economic challenges, necessitating urgent exploration of sustainable alternatives. The conversion of abundantly available biomass into biofuels is attracting significant attention, and it is seen as an innovative technique for addressing environmental problems and attaining net-zero carbon emissions involves balancing carbon output with removal strategies, ensuring that anthropogenic CO2 emissions are fully offset through carbon sequestration, renewable energy adoption, and advanced mitigation technologies. The utilization of a wide range of raw materials as feedstock for biofuel production is dependent on factors such as biomass availability, cost-effectiveness, and geographic location. Lignocellulosic (LC) biomass has received significant attention from researchers worldwide due to its diverse range of basic components, and it is suitable for second-generation biofuel production. This chapter presents an in-depth exploration of the fundamental principles and advanced applications of thermochemical and biochemical conversion processes.
