  • Recently, many studies have focused on the explosive waste treatment in terms of the safety and environmental pollution. A combustion process using fluidized bed incinerator has several profits : continuous process, low pollutive gases such as NOx, and high process efficiency. This study focused on the design of the propellant combustion reactor by using computational fluid dynamics(CFD) simulation technique. As a result, the reactions are successfully simulated in cylindrical incinerator, and. The study will influence to the research about treatment of explosive wastes.

  • Attrition characteristics of PKM1-SU particles, $CO_2$ absorbents for pre-combustion $CO_2$ capture process, and FCC particles, catalytic particles for hydro cracking of crude oil, were investigated at high temperature and high pressure conditions. Particle attrition tests were executed at various kinds of temperature ($0-400^{\circ}C$) and pressure (0-20 bar) conditions in a cylinder type bubbling fluidized bed with 15.1 cm diameter, 120 cm height and 1 mm orifice-sparger tube. Attrited particles before and after tests were analyzed by BET, optical microscopy, and particle size analyzer. Effects of bed material height (solid inventory) and steam injection were also verified by using ASTM D5757-95, conventional attrition test method.
