Coal gasification wastewater (CGWW) is a typical toxic and refractory industrial wastewater. Here, a novel phenol and ammonia recovery process (IPE) was employed for CGWW pretreatment, and the coupled system assemble by the IPE process with A 2 /O system (IPEA 2 /O) were operated to enhance the treatment performance of CGWW. The results showed that the IPE pretreated effluent had a higher ...

Exxon process. In the 1970 s, Exxon company [6], [7], [8] developed a continuous and stable 1 t/d process development unit (PDU) (inner diameter m and height 25 m), as shown in Fig. 1, in which the coal is gasified at 973 K and MPa with 8 wt% KOH and K 2 CO 3 as the catalysts and superheated steam (1073 K) as the gasification agent, respectively.
Cogasification of biomass and coal is an alternative that increases the reliability of power plants while reducing CO 2 emissions [125]. Cogasification of biomass and coal has exhibited a synergistic effect, with many studies reporting that with higher amount of biomass the gasification reaction was promoted [125], [126], [127].
a fuel in the cement plant and other plants. But there is lot of scope for gasification of the petro coke for making the hydrogen or the synthesis gas and now the reliance Jamnagar refinery they are going for the petro coke gasification. So, we will be also discussing about the petro coke gasification gasification of the coal petro coke
Coal gasification is recognized as the core technology of clean coal utilization that exhibits significant advantages in hydrogenrich syngas production and CO2 emission reduction. This review briefly discusses the recent research progress on various coal gasification techniques, including conventional coal gasification (fixed bed, fluidized bed, and entrained bed gasification) and relatively ...
Process: Coal gasification is a process in which coal is partially oxidised with air, oxygen, steam or carbon dioxide to form a fuel gas. This gas is then used instead of piped natural gas, methane and others for deriving energy. Insitu gasification of coal or Underground Coal Gasification (UCG) is the technique of converting coal into ...

The process involves gasification of coal, which in turn will produce synthetic gas (a mix of CO+H2). The synthetic gas can be liquefied to its fuel equivalent in presence of cobalt/ironbased catalysts at higher pressure and temperature. However, liquefied coal emits twice as much CO2 as burning oil. It also emits a large volume of SO2.
Looking at the coal gasification process as a story that has both positives and negatives can show the true nature of how it happened. History of Coal Gasification. Though scientists had studied the process of emitting gas from burning coal since 1780, it would take until the early 1900s when the processes would become commercialized for use ...
