Effect of thermal and alkaline pretreatment of giant miscanthus and Chinese fountaingrass on biogas production
Giant miscanthus (Miscanthus×giganteus) and Chinese fountaingrass (Pennisetum alopecuroides (L.) Spreng), cultivated for landscaping and soil conservation, are potential energy crops. The study investigated the effect of combined thermal and alkaline pretreatments on biogas production of these energy crops. The pretreatment included two types of alkali (6% CaO and 6% NaOH) at 22, 70 and 100 ...

Project - Biogas purification at Mapocho WWTP
Biogas is a mixture of gases, the main components of which are methane and carbon dioxide, produced as a result of the fermentation of organic matter in the absence of air by the action of a microbial consortium (anaerobic digestion). The composition of the biogas depends entirely on the nature of the waste used and the conditions under which anaerobic digestion is carried out. Generally, the ...

Biogas desulphurisation using the DMT multiple stage Sulfurex® process
Global rising energy costs are focusing efforts by many industrial and municipal entities to find new sources of energy. Generating electricity from Biogas is of course nothing new however the cost of cleaning up certain Biogas streams with excessive levels of Hydrogen Sulphide (H2S) has previously proven to be financially unsustainable. Rising energy costs combined with improvements and cost ...

Effect of solid-state NaOH pretreatment on methane production from thermophilic semi-dry anaerobic digestion of rose stalk
The effects of solid-state NaOH pretreatment on the efficiency of methane production from semi-dry anaerobic digestion of rose (Rosa rugosa) stalk were investigated at various NaOH loadings (0, 1, 2, and 4% (w/w)). Methane production, process stability and energy balance were analyzed. Results showed that solid-state NaOH pretreatment significantly improved biogas and methane yields of 30-day ...

Thermochemical pretreatment of lignocellulose residues: assessment of the effect on operational conditions and their interactions on the characteristics of leachable fraction
Annually, large amounts of agricultural residues are produced in Chile, which can be turned into a good opportunity to diversify the energy matrix. These residues have a slow hydrolysis stage during anaerobic digestion; therefore, the application of a pretreatment seems to be an alternative to improve the process. This work focused on applying a thermochemical pretreatment with NaOH on two ...

Biomass alternative fuel: co-combustion of coal explodes!
Biomass fuel blending in Europe Europe has used biomass fuels on a large scale for more than 30 years. The UK has adopted the direct-fired co-combustion route for large coal-fired power plants and has continuously increased the proportion of biomass coupling. Through policy drive, cost management and safety control, it achieved multiple 100% biomass-fired thermal power plants in 2018. ...
