This study was done to evaluate the effect of the hydrothermal treatment on kenaf (Hibiscus cannabinus) fibres high density fibreboard (HDF) at elevated temperatures. Four types of HDF were manufactured, one was untreated and the others were treated at three different temperatures that were 100, 130 and 150 °C for 30 minutes in a laboratory autoclave. The thickness swelling of panel when immersed...
The complexity of the coal gas compositions and their reactions properties affect the sulfidation of H2S with calcium-based-based sorbents, which is not easy to measure quantificationally. Using the ASPEN PLUS software, the reaction degrees between coal gas compositions can be obtained easily. The results show that the thermal decomposition of H2S is affected by temperature greatly and the higher...
Based on a series of static foaming experiments of foam-combined system, and by introducing a parameter, the comprehensive foamability, this paper put forward a new method to evaluate the foaming characteristics and foam stability of foam-combined system. Moreover, this paper has set up corresponding empirical formula. In glass capillary test, the effects of surfactant type, surfactant texture, polymer...
In this paper, the method of Spatial Fourier Transform has been used to investigate the pattern formation dynamics in a dielectric barrier discharge (DBD) system. With this method, patterns formed in the DBD system can be transformed into smooth frequency spectrum. The frequency constitution of discharge pattern can be analyzed. In our experiment mixed gas of 96% Ar and 4% air at 0.9 atm is used as...
