AI Article Synopsis
- Pyrolysis is a thermal process that converts biomass into three products: solid bio-char, liquid bio-oil, and combustible gas, but it struggles with efficiency and product quality using raw biomass.
- Torrefaction is a new pretreatment method that enhances the properties of raw biomass, making it more suitable for pyrolysis.
- The review highlights the benefits of using torrefied biomass in pyrolysis, focusing on improved efficiency and better quality of the resulting products.
Article Abstract
Pyrolysis, one of the most promising thermal conversion technologies for biomass conversion, can decompose biomass into solid bio-char, liquid bio-oil, and combustible gas to meet different energy needs. However, pyrolysis efficiency and product quality are not as good as expected when raw biomass is used owing to the properties of raw biomass (e.g., high moisture, oxygen, and alkali metal contents). Torrefaction is an emerging biomass pretreatment technology that can improve the physical and chemical properties of raw biomass, and pyrolysis efficiency and final product quality can therefore be improved by using torrefied biomass. We review several advantages of pyrolysis of torrefied biomass in terms of the conversion process and final product quality.
