The study investigates the effects of temperature and residence time on the energy density of kesambi leaves through experimental torrefaction. proximate analysis. and response surface methodology with a central composite design (RSM-CCD). The torrefaction process enhances the energy density of kesambi leaves by increasing fixed carbon content while reducing volatile matter. https://www.lecoureures.shop/product-category/ski-de-fond-accessoires-piece-de-rechange/
