In this process, coal is mixed with a recycled solvent and a synthetic iron-based catalyst; after preheating, H 2 is added. The reaction takes place in a tubular reactor at a temperature between 430 °C (810 °F) and 465 °C (870 °F) at the pressure 150-200 bar. The produced oil has low quality and requires intensive upgrading. [14]
Sulfuryl chloride is used as a source of Cl 2.Because it is a pourable liquid, it is considered more convenient than Cl 2 to dispense.. Sulfuryl chloride is used in the conversion of C−H to C−Cl adjacent to activating substituents such as carbonyls and sulfoxides: [5] [6]
A large compost pile can spontaneously combust if improperly managed. Spontaneous combustion or spontaneous ignition is a type of combustion which occurs by self-heating (increase in temperature due to exothermic internal reactions), followed by thermal runaway (self heating which rapidly accelerates to high temperatures) and finally, autoignition.

The flames caused as a result of a fuel undergoing combustion (burning) Air pollution abatement equipment provides combustion control for industrial processes.. Combustion, or burning, [1] is a high-temperature exothermic redox chemical reaction between a fuel (the reductant) and an oxidant, usually atmospheric oxygen, that produces oxidized, often gaseous products, in a mixture termed as smoke.
To minimize the problem, the combustion is often conducted in the presence of calcium oxide or calcium carbonate, which, directly or indirectly, bind sulfur dioxide and some oxygen to give calcium sulfite. [1] The net reaction is: CaO + SO 2 → CaSO 3 2 CaSO 3 + O 2 → 2 CaSO 4. or the net reaction is sulfation, the addition of SO 3: CaO + SO ...
The overall reaction in the CLR system is a combination of the partial oxidation reaction of the fuel and the WGS reaction: CH 4 + 1-a / 2 O 2 + a H 2 O → CO + (2+a) H 2. It is noted that the actual reaction products for such reactions as those given above can vary depending on the actual operating conditions.
Char is the solid material that remains after light gases (e.g. coal gas) and tar have been driven out or released from a carbonaceous material during the initial stage of combustion, which is known as carbonization, charring, devolatilization or pyrolysis.
Chemical looping combustion (CLC) is a technological process typically employing a dual fluidized bed system. CLC operated with an interconnected moving bed with a fluidized bed system, has also been employed as a technology process. In CLC, a metal oxide is employed as a bed material providing the oxygen for combustion in the fuel reactor.
