Sulfur removal at high temperature during coal

01-01-2003  When CaO and some additives are added into coal briquette at Ca/S=2, it is found by XRD and X-ray fluorescence analysis (XRFA) that the CaS phase is the main sulfation product and retains a sulfur content of 4.7% in a desulfurization residue obtained at 1300 °C. This is higher than the sulfur content of 1.8% in raw coal ash .

Process for removing sulfur from coal - The

Gaseous chlorine is bubbled through the slurry at 60°-130° C. and 0-60 psig from 45 to 90 minutes to oxidize the coal. The process will remove about 60% of total sulfur in the coal, removing about 50% of the organic sulfur and 70% of the pyritic sulfur. While the process is reasonably effective, about half of the organic sulfur remains in the coal.

Hydrodesulfurization - Wikipedia

Hydrodesulfurization is a catalytic chemical process widely used to remove sulfur from natural gas and from refined petroleum products, such as gasoline or petrol, jet fuel, kerosene, diesel fuel, and fuel oils. The purpose of removing the sulfur, and creating products such as ultra-low-sulfur diesel, is to reduce the sulfur dioxide emissions that result from using those fuels in automotive vehicles, aircraft, railroad

Sulfur Coal - an overview ScienceDirect Topics

This process involves molten media gasification where both caking, high ash and high sulfur coal can be gasified. The crushed coal is injected into a molten and iron bath, followed by steam lancing. The process operates at 1371°C. Volatile matters crack at this temperature and both CO and H 2 are formed.
