Ceramic honeycombs are applied in the biomass regenerative gasifier to recycle the sensible heat of the syngas to heat the gasification agents, and ceramic honeycombs are used as Ni catalysts carrier to crack the tar in the syngas. Experiments on gasification of pine with different air equivalence ratio (ER) and steam/carbon mole ratio(S/C) have been carried out in this paper. Experimental results show that the heat recycle of the ceramic honeycombs can effectively promotes the gasification temperature and the syngas calorific value, and the Ni catalysts can effectively crack tar. Meanwhile, the gasification method of the gasifier can keep the activity of the catalysts for a long time. (c) 2012 Elsevier B.V. All rights reserved.
