PDF | Presently, biomass is mostly utilized as cofuel in coal combustion in view of energy diversification and emission reduction. However, since the coal content of biobriquettes is high (up to ...
While the SX/EW process was adopted by the industry to take benefit from the sulfuric acid that the smelting process produced steps are being take to divorce the two. The Phelps Dodge Mining Company, for example, at its Morenci, Arizona mine, has completely disassembled its smelter and has converted the mine to a mineforleach operation.

New technology removes sulfur from coal By Susan Trulove. Spectrum Volume 19 Issue 01 August 29, 1996 . A coalcleaning technology developed by ia Tech in the early 1980s has generated new technologies and patents, including a process for doubling the amount of sulfur removed from coal compared to techniques currently used.
Coal briquettes have long been produced as a means of using up ''small coal'', the finely broken coal inevitably produced during the mining process. Otherwise this is difficult to burn as it is both hard to arrange adequate airflow through a fire of these small pieces, also it tended to be drawn up and out of the chimney by the draught, giving visible black smoke.
sulfur in the coal to fix about 6080% of the sulfur into the ash. Many coal ranks can be used, including bituminous coal, subbituminous coal, and brown coal. In particular, the biobriquettes produced with low grade coal containing large amounts of ash and having low calorific value combust cleanly, thus the .
To date, no economically feasible process for organic sulfur and hazardous air pollutant (HAP) precursor removal from coal has been developed. However, a hydrothermal method based on supercritical water extraction techniques developed at the University of North Dakota Energy and Environmental ...

into the flue gas, the sulfur removal efficiencies were only 4060% [17]. Moreover, when the adsorbents were physically mixed with the coal, the desulfurization efficiencies were usually lower than 40% [17,18]. In recent years, a biobriquette produced from a mixture of coal and biomass under highcompression pressure has been developed.
Clean coal briquette is one of the most effective techniques to remove SO2 from coal combustion by using sulfurretention agent to retain sulfur in coal residuals. Ca(OH)2 has been proved to be an ...
The process of coalbased direct reduction followed by magnetic separation was employed to produce direct reduction iron powder (DRIP) from a refractory lowgrade iron ore. The desulfuration behavior of the composite briquettes during this process was studied. Experimental results showed that this process presents advanced sulfur removal ability.
Clean coal briquette is one of the most effective techniques to remove SO2 from coal combustion by using sulfurretention agent to retain sulfur in coal residuals. Ca(OH)2 has been proved to be an effective sulfurretention agent. CaSO4 as the primary sulfurcontaining product, however, is thermal unstable at high temperatures. It has been reported that SiO2, Al2O3, Fe2O3 etc. are excellent ...
Abstract. A process is disclosed for the removal of divalent organic and inorganic sulfur compounds from coal and other carbonaceous material. A slurry of pulverized carbonaceous material is contacted with an electrophilic oxidant which selectively oxidizes the divalent organic and inorganic compounds to trivalent and tetravalent compounds.

A process for preparing a coal or lignite fuel that contains sulfur for combustion wherein reduced amounts of sulfur containing air contaminants are emitted from the combustion is disclosed. In the disclosed process, the coal or lignite that contains sulfur is first pulverized and is then mixed with a finely divided inorganic material.
