“…The properties of raw materials are shown in Table 1 . The moisture content, organic carbon, and total nitrogen of corn stalks were 5%, 42.35%, and 0.9% respectively which is consistent with the results of other researchers [ 24 ]. The moisture content of deer manure is higher than that of other studies [ 25 ].…”

“…Several previous studies have shown that torrefaction of biopellets can increase the calorific value and energy density values compared to raw material. The torrefied biopellets are good feed for gasification and combustion [2,3,4,7,8,9].…”

This present paper is focused on the investigation of combustion characteristics of torrefied pellet biomass from agricultural waste. Four biomass pellet samples such as sugarcane bagasse, Napier grass, Palm Empty Fruit Bunches, and Cassava stem were torrefied in a designed cylinder tubular pyrolysis reactor. The reactor was set up under 30 min of residence time, and the temperature reaction was varied at 200, 250, and 300 °C in an inert atmosphere. The torrefied products were then characterized in terms of their psychochemical properties such as proximate, ultimate, calorific value, and combustion properties. The combustion properties of raw and torrefied biomass pellets during the combustion process were investigated by the thermogravimetric analyzer Exstar SII TG/DTA7300. The samples were heated at an ambient temperature up to 800 °C at a constant heating rate of airflow at 10 °C/min in airflow. The results showed that the moisture content and volatile matter of torrefied pellets decreased by 2 to 5% and 8 to 14%, subsequently. Otherwise, the fixed carbon content is up to three times higher than the raw material. The study conclusively that torrefaction can also able to enhance combustion performance in terms of ignition and burnout temperature, ignition and burnout index, and combustion rate. The results shows that, the ignition and burnout temperatures of torrefied pellets are higher than raw material. The ignition and combustion index of torrefied pellets are lower than raw material, and the torrefied pellets have a longer burning time and a higher combustion temperature.

As a biological by-product, cornstalk will pose a huge threat to the development of sustainable agriculture and environmental protection if it is not fully utilized. In this study, the macrostructure was characterized by optical camera and the chemical composition of cornstalk rind and cornstalk pith was characterized by Fourier transform infrared spectroscopy (FTIR). The test results show that the cornstalk was divided into rind and pith macroscopically, the cornstalk is smooth outside, and the pith is a sponge-like structure, the fiber structure evenly distributed on the pith. FTIR analysis showed that the cornstalk was presumed to be aliphatic compounds containing C-H chains and rich in fatty acids and/or ketones, and the main components include cellulose and lignin. The results of this study provide new inspiration and reference for the post-processing of cornstalks.
