The porous alumina tube with pore gradient along the radial direction was successfully fabricated, where PMMA particles were used as pore former agent. The specimen was expected as a filter subjected to high temperatures. Alumina and PMMA particle were mixed with water to form aqueous slurry, compacted using centrifugal molding technique. The green body was dried in partial vacuum atmosphere, calcinated at 273 K to remove the organic component, sintered at 1623 K to obtain sintered porous a-alumina tubes. The control on the pore gradient of porous tubes was attempted by two ways; lamination and continuous methods. The microstructure observation showed that the inner part of the tubes had higher porosity than the outer part irrespective of the method used. Porous alumina tubes were characterized by microstructure observation, porosity and air permeability. The binary pores of 10µm and submicron in diameter were visible, which were formed by the burning-out PMMA particles and lower sintering temperature, respectively. The influence of PMMA amount on the pore morphology of the tubes was investigated. Fracture strength was carried out by the O-ring diametral compression testing. An analytical formula subject to the diametral testing was introduced with considering the porosity gradient. The correlations between the fracture strength and pore gradient were investigated, where a reduction in fracture strength was observed with the increase in laminated layers, and minimum strength was found in continuous porous tubes.

Microwave catalytic pyrolysis of sewage sludge were conducted on a single mode microwave reactor. The effects of CaO and steam on hydrogen-rich gas formation characteristics were analyzed. The results indicated that the CaO can improve the formation of H2and CO. When CaO in sewage sludge increased from 0 to 0.75 g/(g dried sludge), the H2and CO concentration increased from 62 vol.% to 77 vol.%, while CH4and CO2concentrations decreased from 28 vol.% to 9 vol.%. The steam can also improve the formation of H2and CO, with 1.59 g/min of the steam flowrate, the H2and CO concentration increased to the maximum of 81 vol.%, and the CH4and CO2concentration decreased to the minimum of 16 vol.%. When the steam gasification was coupled with the CaO catalyzing, the H2concentration can reach to 61 vol.%, which was 79.3% higher than the experimental conditions absent of steam and CaO.
