Production of Activated Carbon from Palm-oil Shell by Pyrolysis and Steam Activation in a Fixed Bed Reactor
The research objective was to produce activated carbon from palm-oil shells by one step pyrolysis and steam activation in a fixed bed reactor with the diameter of 100 mm. The studied variables were activation temperature, activation time, palm-oil shell sizes and flow rate of air. The results showed that the optimum condition was 1.18-2.36 mm of palm-oil shells at 750C for 2 hr with air flow ra...
متن کاملPressurised pyrolysis of Miscanthus using a fixed bed reactor.
Miscanthus x giganteus was pyrolysed, in a fixed bed reactor in a constant flow of dinitrogen gas, at a rate of 13°C/min from ambient to 550°C, then held for 25 min at this temperature. The pressures employed ranged from atmospheric to 26 bar. The major compounds identified in the bio-oil were water, phenol, and phenol derivatives. The water contents impact on the usefulness of the bio-oil as a...
متن کاملProduction of Bio-oil by Oxidative Pyrolysis of Sewage Sludge in Rotating Fixed Bed Reactor
Pyrolysis is an attractive thermal conversion technology used to produce bio-oil and some chemicals. In this study, we investigated the pyrolysis of sewage sludge under N2 and CO2 atmosphere at various temperatures (350-750°C) in a rotating fixed bed reactor. For under N2 atmosphere, thermal gravimetric analysis (TGA) shows two major reaction peaks centered at 300 and 500°C. However, if CO2 was...
متن کاملTrimetallic Au-Cu-La/AC for Acetylene Hydrochlorination in a Multi-Tubular Fixed Bed Reactor
The metal chloride of LaCl3 was chosen to modify the Au-Cu/AC to decrease the noble metal of gold and enhance the catalytic performances. Then a mercury-free catalyst of Au-Cu-La/AC was prepared by the impregnation method, and the fresh Au-Cu-La/AC and Au-Cu/AC catalysts were also characteri...
متن کاملHeat and Mass Transfer in Fixed-bed Tubular Reactor
Heat and mass transfer problem in a fixed-bed tubular reactor is one of the major concerns in the chemical engineering. The two dimensional axial plug flow model was used for a water gas shift reactor to compare heat conduction or mass diffusion with convective effect. In the case of fast fluid flow in highly permeable catalyst-bed, convective heat transfer was dominant compared to heat conduct...
