The catalytic pyrolysis of palm oil wastes was investigated using of the self-developed Nano-NiO/γ-Al2O3 catalyst, coke and dolomite catalyst. Meanwhile, the catalytic properties of different catalysts were evaluated. The experimental results showed that the catalytic activity of nickel-based catalyst was the best with higher cracking efficiency at 700°C, followed by dolomite. The nickel-based catalyst...
In this paper, CuO was selected as a catalyst in the production of lactic acid from glucose under alkaline hydrothermal conditions. The addition of CuO can improve the yield of lactic acid efficiently. The highest yield of 37% was obtained under the optimum conditions, i.e., reaction temperature 300 °C, reaction time 60 s, CuO 0.3 mmol and NaOH 2.5 M. An efficient method for producing lactic acid...
The effects of different catalysts (homogeneous catalysts: NaOH, Na2CO3, KOH and K2CO3; heterogeneous catalysts: JB-1, JT-201 and JT-203) on the hydrothermal liquefaction of biomass under CO atmosphere were investigated mainly using a high-pressure autoclave reactor at 380°C. The results indicated that the conversion of biomass and the yield of liquid products increased obviously with the adding of...
The catalytic steam gasification of municipal solid wastes (MSW) for fuel gas production was experimentally investigated in a combined fixed bed reactor using the newly developed nano-NiO/γ-Al2O3 catalyst. A series of experiments have been performed to explore the effects of catalyst presence, catalytic temperature, steam to MSW ratio (S/M) and MSW particle size on the composition and yield of gasification...
