The Ash-Forming Element Migration and Mineral Transformation during the Bamboo Combustion Process.

To investigate the effect of combustion temperatures on element transformation of ash, bamboo was fired using a muffle furnace at 550, 600, 700, 800, 900, and 1000 °C. Chemical compositions, micromorphology, and mineral and thermal behavior of ash were characterized. The main components included KO, SiO, PO, MgO, and CaO at a temperature of 550 °C.

Effect of Deashing Treatment on Ash Fusion Characteristics of Biochar from Bamboo Shoot Shells.

To investigate the influence of deashing on fusion characteristics, a combined method of water and acid washing with different sequences (water washing followed by acid washing, and acid washing followed by water washing) was used to treat the biochar of bamboo shoot shells (BBSSs). The results show that deashing decreased the K content of the biochar from 50.3% to 1.

Activated Carbon with Ultrahigh Specific Surface Derived from Bamboo Shoot Shell through KFeO Oxidative Pyrolysis for Adsorption of Methylene Blue.

To effectively remove methylene blue (MB) from dye wastewater, a novel activated carbon (BAC) was manufactured through co-pyrolysis of bamboo shoot shell and KFeO. The activation process was optimized to a temperature of 750 °C and an activation time of 90 min based on its excellent adsorption capacity of 560.94 mg/g with a yield of 10.

Pyrolysis self-activation: An environmentally friendly method to transform biowaste into activated carbon for arsenic removal.

A green method for production of activated carbon and combustible gas was introduced. Without any external reagents and gases, the HO and CO produced by the pyrolysis of bamboo shoot shells were used as activators. The prepared activated carbon had good arsenic adsorption properties with the maximum adsorption capacities of 10.
