“…This process can be categorized into slow, fast, and flash pyrolysis based on the process parameters used such as temperature, heating rate, and gas phase residence time [55,56]. Multiple reactions occurring during pyrolysis can be classified into three stages based on temperature [10,57] Proteins and carbohydrates decompose at temperatures below 400 • C. Around the pyrolysis temperature of 550 • C, lipids are broken down into fatty acids, which in turn may be converted to ketones, aldehydes, acids, alkenes, and other compounds [58].…”
