Pyrolysis is one of the widely used technique among the thermal conversion processes of biomass. Biomass in the form of agricultural residues is prevalent in new renewable energy sources, especially in view of its broad potential and rich use. In this paper, the pyrolysis of chickpeas and peanut shells in laboratory-scale tubular furnace reactors is studied, which is considered to be an effective method to utilize agricultural residues in China. The effects of raw material ratio and reaction temperature on the distribution of pyrolysis products are described quantitatively, as well as some characteristics of these products produced in the tubular furnace reactor system developed in this study. The main constituents of bio-oil are categorized into three kinds including aromatic compound, carbonyl compounds and carboxyl compounds that were analyzed with 1H NMR (nuclear magnetic resonance characterization). The maximum yield of bio-oil, about 44.80% from the peanut shell biomass, and 10.3% from the waste of chickpeas by weight was extracted, at a flow rate 10 L/min of N2 at a reaction temperature of 500°C was achieved.
