Scaled-up reactor for microwave induced pyrolysis of oil palm shell
We designed and implemented bench-scale equipment for the microwave pyrolysis of biomass, and tested its effects on oil palm shell (OPS). The design uses the interference of two MW sources to increase the electric field intensity, based on model predictions by finite elements simulations. The MW pyrolysis experiments were done varying the mixture ratio of OPS and activated carbon (75:25, 50:50, or 25:75 by weight), the MW power (450 or 800W), and the use of MW source magnetrons (left, right, or both). The pyrolysis temperature depended on the varied experimental parameters. The highest temperature and the highest yields of liquid bio-oil and gas were obtained with the 75:25 mixture treated with 800W total power using both magnetrons. The end-products were analyzed with bomb calorimeter, GC MS, and the solid residue with SEM. The results demonstrate that the bench-scale equipment is suited for experimental work on the pyrolysis of biomass (OPS). (C) 2016 Elsevier B.V. All rights reserved.
