Bio-oil is a broad concept. Currently, it generally refers to biofuels, most of which are alcohol-based.
Used in catering, canteens and industrial fuels.
The composition and physical and chemical properties of bio-oil are affected by many factors, such as raw material type, water content, reactor type, reaction parameters, methods of collecting products, etc. However, bio-oil produced by different methods still has some common properties, such as high moisture content, particle impurities, high viscosity, poor stability, corrosiveness, etc., are very different from petrochemical fuels traditional (diesel, gasoline), and also pose many challenges to the difficulty of using bio-oil in diesel engines.
Bioenergy refers to renewable energye which uses biological activities to convert biomass, water or other inorganic substances into combustible gases such as biogas, hydrogen or flammable liquids such as ethanol and grease as carriers.
Biomass includes plants, animals and their excrement, organic waste and wastewater.
There are many specific types of biomass. The most important types of plants that we often see include wood, crops (straw, rice straw, wheat straw, bean straw, cotton straw, straw, etc.), weeds, algae, etc. Non-plant categories mainly include animal feces, animal carcasses, organic components of sewage, organic components of waste, etc.
Common bioenergy sources include: (1) fuel ethanol (2) biodiesel (3) biogas (4) biobutanol (5) microalgae oil production (6) energy production from biomass
