Abstract This paper studied the synergistic effects of CaO or Al2O3 and three potassium phosphates (e.g., KH2PO4, K2HPO4·3H2O and K3PO4·3H2O) in the rice stalk pyrolysis through pyrolysis-gas chromatography-mass spectrometer (Py-GC/MS) experiments. The results show that after co-catalyzed by CaO/Al2O3 and potassium phosphates, the total contents of phenols, aldehydes, acids, LG from most samples decrease and those of ketones increase compared with those catalyzed by potassium phosphates alone. CaO/Al2O3 and potassium phosphates show synergistic effects in the regulation of the types or contents of phenols, ketones, aldehydes, etc. and are suitable for the production of ketone-rich bio-oil. Dehydration reactions, etc. are further promoted under the co-catalysis of the two catalysts, and some phenols can be converted to benzene products, etc. The contents of acetic acid can decrease to 0. For 50% K3PO4.3H2O impregnated sample, the yields of furans reduce sharply after CaO addition. For most impregnated samples except 50% K2HPO4·3H2O sample and 30%, 50% K3PO4.3H2O, the contents of total furans and furfural increase after Al2O3 addition.

Microwave pyrolysis of sewage sludge was conducted in a single-mode microwave oven. The influencing effects of experimental factors, including particle size and moisture content of sewage sludge, pyrolysis temperature, and shape of microwave adsorber, on concentration of pyrolysis gas products were studied. The results indicated that with the decrease of particle size, the H2 concentration increased from 31 vol.% to 34 vol.%, and CO concentration increased from 17 vol.% to 22 vol.%. When the moisture content of sewage sludge increased from 0 to 83 wt.%, the H2 concentration increased from 32 vol.% to 42 vol.%, and the CO concentration increased from 20 vol.% to 31 vol.%. Compared with microwave adsorber in powder phase, the microwave adsorber in fixed structure can transform more volatile compounds to uncondensable gas, and the concentrations of H2 and CO were also slightly increased.

In order to study the effects of laminated structure on acoustic insulation property of composites, the frequently-used flexible polyvinyl chloride (EPVC) sheets and non-woven fabric were selected as the substrate materials to prepare for ten types of nonwoven fabric/EPVC composites with different laminated structures in this study. Their acoustic insulation properties were tested and analyzed by the double channel acoustic instrument. The results showed that the different laminated order of composites has significant influence on its acoustic insulation property under the same conditions; and the acoustic insulation property of composites can be improved by the change of laminated order only.
