In adaptive harmonic current detecting method based on the principle of adaptive noise cancellation, there is a contradiction between the detecting accuracy and the detecting speed. The accuracy can be improved by using a lower learning rate, but it will be accompanied by the deterioration in dynamic response, and vice versa. This is because that there are a series of pulsating components in the weight...
In order to improve the efficiency of straw dry anaerobic fermentation biogas production and find the optimum technological conditions, we research such factors which affect biogas as different pretreatments, straw size, the adding amount of inoculum and C:N ratio materials. Experimental results show that under the conditions of the medium temperature (35degrees) and 20% of total solids, we make use...
This article reviewed the development of lignocellulosic biomass pretreatment technology, influencing parameter of anaerobic fermentation and fermentation technology. The characteristic of lignocellulose is analyzed. Pretreatment of Lignocellulosic biomass including physical, chemical, biological and thermal pretreatments. Influencing parameter of anaerobic fermentation including temperature, inoculum,...
