The carbonization of Nannochloropsis gaditana microalgae biomass was found to produce biocoal that is similar to bituminous coal used in thermal power plants. Currently, microalgae that capture CO 2 while they are in the growth stage are considered a source for the production of biofuels. The carbonization of biomass for producing biocoal has received attention for its ability to improve the ...
Mass of the recovered process water was calculated by subtracting the dry mass of biocoal from the combined mass of process water and biocoal. Inorganic analysis. The biocoal and raw biomass to be used for analytical purposes were air dried and homogenised in a Retsch grinder.
Bassani et al. proposed a novel methanol production process from coal gasification. They used Aspen HYSYS® for the process simulation and GASDS for the simulation of the coal gasifier. ... % for production of biooil, and % in the case of biochar, which is higher than methanol production via GASIF (53%). Reduction in carbon dioxide ...
Hong Kongbased SSGE BioEnergy is joining the green revolution by making bio coal as an alternative to the dirty fuel. ... The technology uses a process called torrefaction, which heats biomass ...
Metal production, and especially iron orebased steel production, is characterized by high fossil CO2 emissions due of the use of coal and coke in the blast furnace. Steel companies around the world are striving to reduce the CO2 emissions in different ways,, by use of hydrogen in the blast furnace or by production of iron via direct reduction. To partially replace fossil coal and coke ...
Life cycle assessment further shows that the biocoal production process could achieve net positive energy, financial, and environmental benefits. By using available biomass wastes as feedstock, China is expected to have a total biocoal production of 402 million tons of standard coal equivalent, which is equal to 13% of national coal consumption.
Due to global warming, technologies reducing CO2 emissions in the metallurgical industry are being sought. One possibility is to use biocoke as a substitute for classic coke made of fossil coal. Biocoke can be produced on the basis of coal with the addition of substances of biomass origin. Blends for the production of biocoke should have appropriate cokemaking properties to ensure the ...
A method for producing a biocoal includes the following steps: (a) lowering the moisture content of a fiber residue obtained after oil extraction of oil palm fruit to less than 25%; (c) after step (b), pelletizing the fiber residue into shortfiber pellets; (d) drying the shortfiber pellets to reduce the moisture content of the shortfiber ...
Process flow diagram for bio coal production from bagasse 4. Conclusion Sugarcane bagasse, a waste by product from the sugar processing industry can be used for the production of a solid fuel which has a high calorific value of around MJ/kg using the torrefaction technology. The bio coal can be used as a replacement to coal due to the high ...
In the coalfired boiler for coalfired power generation provided by the present invention in the semicarbonization apparatus and manufacturing process for the production of biocoal that can be mixed with coal, the first screw of the transfer screw (4) and the drying unit (6) installed in a recuperative manner ( 8), the rotational speed of ...
The main objective of this study is to determine the total decrease in the sulfur content in a blend of coal and biomass in which a fermentation process was carried out using a bioactivator for 24 h.
The biocoal production process was analyzed with two different operational aspects: (A) fast pyrolysis for biooil production and (B) fast pyrolysis in addition to atmospheric distillation for biocoal synthesis. ...
