Environmental deterioration and the need for energy security are intrinsic problems linked with the linear economy based on fossil fuels. Recently, a transformation to a sustainable circular bio-econo...
This study investigated the effect of factors namely temperature, pH, substrate concentration on sago and tannery effluents by the anaerobic digestion process for biogas production. Response surface m...
This paper presents analyses of the thermal characteristics of construction details at the biogas station plant, in order to investigate the impact of the thermal bridges on the energy consumption. Th...
The article is aimed at verification of the effect of chaff length of fermented material and duration time of the contact of material with oxygen before dosing into the fermenter, on production and en...
为了促进芦笋秸秆原料沼气发酵系统的产气效果,利用NaOH在无流动水的条件下对芦笋秸秆进行了碱性化学预处理,并在小型沼气发酵装置上以不同预处理时间、粒径和NaOH溶液质量分数对芦笋秸秆木质纤维素的变化及产沼效果的影响进行了试验研究。结果表明,预处理时间15~20d比不经预处理的试验组启动时间提早10d;芦笋秸秆粉碎和切割后,不经筛分的试验组比经过筛分后的试验组启动时间提早5~15d,发酵周期缩...
Due to an increase in demand for energy and the mobility of the human population as well as in order to keep sustainable development, there is a major need to utilize alternative energy sources. The u...
Purpose: The aim of the paper is to present the construction of a mini digester for biogas production from different agriculture plant biomass and other organic wastes. The amount of biogas production...
Purpose: of this paper is to compare mesophilic and thermophilic anaerobic digestion of three maize varieties. Parameters such as biogas production and biogas composition from maize silage were measur...
BIOGAS - A RENEWABLE SOURCE OF ENERGY     biogas  fermentation       2009/10/14
First part of the paper deals with biogas produced in the process of anaerobic digestion. Possibilities of biogas utilization are commented briefly. Laboratory fermentation unit that was built at the ...
运用实验室自行设计的小型沼气发酵装置,以废弃的甘蓝菜叶作为发酵原料,研究了温度对蔬菜废弃物沼气发酵产气特性的影响。结果表明,中温条件((35±1)℃)试验组的挥发酸质量浓度、氨态氮质量浓度以及pH值都在正常范围内,且优于高温((55±1)℃)和室温发酵试验组,可保证系统的顺利运行。产气特性研究表明:中温条件的总产气量比高温条件总产气量高42.5%,最高甲烷含量比高温条件和室温条件下分别高7.6%和...
采用可控恒温厌氧发酵装置,选用牛粪、鸡粪、稻秆3种原料,按干物质比例0∶2∶1、0.4∶1.6∶1、0.8∶1.2∶1、1.2∶0.8∶1、1.6∶0.4∶1、2∶0∶1混合,研究了各配比在15℃、20℃、25℃、30℃下的厌氧发酵情况。结果表明:随温度升高,各配比产气速率和累积产气量均增大,15℃下发酵周期最长,其他温度对发酵周期影响无显著差异;不同配比下,累积产气量均呈先增大后减小的趋势,牛粪...
From the standpoint of the environmental load, it is important to develop the hydrogen production system from methane produced by the fermentation of food waste or biomass. Compared with conventional...
The basis of the biogas production in agriculture is the processing of waste agricultural products (particularly excrements of farm animals but also phytomass). Different but rather similar is the bio...
Purpose: of this paper is to present the construction of a mini digester for biogas production from different energy plants and organic wastes. With the mini digester the amount of biogas production (...
