Climate change and the unsustainability of fossil fuels are calling for cleaner energies such as methanol as a fuel. Methanol is one of the simplest molecules for energy storage and is utilized to generate a wide range of products. Since methanol can be produced from biomass, numerous countries could produce and utilize biomethanol. Here, we review methanol production processes, technoeconomy ...
Background Similar to biofuels, numerous chemicals produced from petroleum resources can also be made from biomass. In this research we investigate cradle to biorefinery exit gate life cycle impacts of producing acetic acid from poplar biomass using a bioconversion process.

This process is an alternate strategy for converting the waste biomass into valueadded products like biochar, syngas and biooil. During the process, the lignocellulosic components like cellulose, hemicellulose and lignin undergo reaction processes like depolymerization, fragmentation and crosslinking at specific temperatures resulting in a ...
In pyrolysis, lignin, cellulose, and semicellulose, the main com ponents of biomass are quickly thermochemically decomposed in seconds to form smallmolecule compounds, in which about 50% of the volatiles can be condensed to form biooil. The carbon content of biooil ranges from 30 to 50%, and the high heating value (HHV) is about 15 MJ kg−1.

Biofuels are playing an increasingly important role since they are an attractive alternative to fossil fuels, access to which has been limited. Moreover, they can help the European Union countries meet their climate and energy objectives. There is a growing interest in the production of biofuels from the organic fraction of municipal solid wastes as secondgeneration biofuels. Such a solution ...

A new type of energy is produced via a fast pyrolysis coupled with atmospheric distillation from lignocellulosic biomass ...
In energy scarcity, particularly in Agribased developing economies, biocoal briquetting is the most suitable means of meeting sustainable energy needs utilizing agricultural waste. In this study, briquettes were made from an indigenously designed briquetting machine for investigating coalbiomass proportion blend using coal from Dara Adam Khel, Khyber Pakhtunkhwa in Pakistan, and ...
Coke corresponds to 2/33/4 of the reducing agents in BF, and by the partial replacement of coking coals with 510% of biocoal, the fossil CO2 emissions from the BF can be lowered by ~48%. Coking coal blends with 5% and 10% additions of biocoals (pretreated biomass) of different origins and pretreatment degrees were carbonized at laboratory scale and with a 5% biocoal addition at ...
Biocoal briquette formulation and production . The biocoal briquette production process was reported by Adeleke et al. materials used were in accordance with the typical formulation shown in Table Table1 1 for the total briquette weight. Representatively, 8P7 M for blended binder composition implied that 8% pitch and 7% molasses were added as part of the total briquette weight, as ...
Biomass briquetting is gradually emerging as a means of sustainable energy production. The interest in briquetting has been occasioned by the continuous rise in the cost of energy coupled with the need to harness efficient and affordable alternatives. Briquettes are produced through various means, ranging from a simple lowpressured technique to a highpressured technique. This, including the ...
M. Tod, in The Coal Handbook: Towards Cleaner Production: Coal Utilisation, 2013 Materials with ultrafine particle size There has been considerable difficulty in the commercial use of a number of finegrain materials and coal tailings as fuels or sources of heat, due to their ultrafine particle size, heterogeneity and high water content.
substitute for coal in most applications and in boilers. Briquettes can be produced with a density o f g/cm³ from loose biomass of bulk density to g/cm³ These can be burnt clean and therefore are ecofriendly arid also those advantages that are associated with the use of biomass are present in the briquettes.

VII. MANUFACTURING PROCESS This project is called biomass briquetting project and is simply a process of converting agro waste and forestry waste into biomass briquettes/bio coal. The biomass briquetting is the best renewable source of energy for healthy environment and economy. It's a complete eco friendly project.
A typical coke manufacturing process is shown schematically in Figure Coke manufacturing includes preparing, charging, and heating the coal; removing and cooling the coke product; and cooling, cleaning, and recycling the oven gas. Coal is prepared for coking by pulverizing so that 80 to 90 percent passes through a

Biocoal is ecofriendly, renewable energy fuel, economical cheaper contain high density. Government is providing tax benefit and incentives. It has easy mobility and transportation. Biocoal is solid fuel. The process of converting biomass to solid fuel is also nonpolluting. No addition of any binder/ chemical is required so it is natural.
Pyrolysis is a wellestablished thermochemical process that involves the thermal breakdown of biomass into various fuel components such as biochar, biooil and pyrolysis gas (A. V. Bridgwater, 2011).
