A few coalrich countries has carried out research on coal liquefaction and gasification technologies, and South Africa has reached the industrialization stage. China is rich in coal resources but has little natural gas or oil (Yang et al., 2001；Xie et al., 2010; Li, 2011), making coal the primary source of energy in China. The Chinese ...

Final products of pyrolysis are in different forms like solid (coal), liquid (oxygenated oils), and gas (methane, carbon monoxide, carbon dioxide). Biomass can be converted into biogas, biooil, and biocoal during pyrolysis. •. Lowtemperature gasification. The basis of this technology is heat decomposition.

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 ...

The bio coal briquette making process. The briquette process with the way below. Raw biomass waste ⇒ Drying (natural drying or dryer) ⇒ crushing (crusher) ⇒ Briquetting (log briquette maker) The raw biomass should be dried first if that was with a moisture too high, then the dried material can be crushed by a crusher. In order to save ...

Climate change, socioeconomical pressures, and new policy and legislation are driving a decarbonization process across industries, with a critical shift from a fossilbased economy toward a biomassbased one. This new paradigm implies not only a gradual phasing out of fossil fuels as a source of energy but also a move away from crude oil as a source of platform chemicals, polymers, drugs ...

The most sortout agricultural residue that finds great use for bioethanol production is the corn stover, and the rice and wheat straws. These crops are abundant all through the year, leaving behind enormous waste during its processing; however, very little attention is given to its biofuel production potential.

The briquetting process is the conversion of agricultural waste into uniformly shaped briquettes that are easy to use, transport, and store. The idea of briquetting is using materials that are unusable, due to a lack of density, and compressing them into a solid fuel of a convenient shape that can be burned like wood or charcoal.

BioCoke is a new densification product produced from biomass that aims to substitute coal coke usage. BioCoke is known to have a better density ( kg/m 3) and mechanical strength at both room ( MPa) and at high temperatures (700 °C) ( MPa) which makes it suitable for use in many practical applications [22,23,24].

This review article focuses on recent studies using hydrothermal carbonization (HTC) for producing hydrochar and its potential application as a solid fuel pellet. Due to the depletion of fossil fuels and increasing greenhouse gas (GHG) emissions, the need for carbonneutral fuel sources has increased. Another environmental concern relates to the massive amount of industrial processing and ...

In addition, the HTC is a thermochemical conversion process operated under mild temperatures with autogenerated pressure which could produce solid material called biocoal or hydrochar, depending on its application, carbon content, and energy property [11]. Therefore, in this study, an energy densified biocoal is required and extended to focus.
