Avg score: 0% Most missed: “Which of the following are types of pyrolysis?”
Biomass conversion technologies are processes that transform biomass into energy or other valuable products. These technologies can be categorized into physicochemical, thermochemical, and biochemical conversion processes.  Some examples of biomass conversion technologies are: Hydrothermal liquefaction: A thermochemical process that turns wet biomass into a liquid fuel. It's also known as direct liquefaction and is used to convert bio-organic waste with high water content. Biochar: Produced through pyrolysis or gasification, which are processes that heat biomass in the absence of oxygen.... Show more
