Initially, the ,desulfurization, studies were performed using a model diesel contg. a mixt. of the most refractory sulfur compds. and later extended to an untreated real diesel. In both cases, acetonitrile was used as extn. solvent and aq. H2O2 as oxidant. High level ,of desulfurization, was achieved using model and untreated diesels after few hours.

The ,desulfurization, processes of interest in this program are the lime, limestone, and double alkali wet scrubbing of flue gases produced in the combustion of coal in steam power plants. More specifically, problems associated with FGD waste disposal are being defined, and assessments are being made of the operational feasibility, performance, and costs of current disposal methods.

In the presence of an acid catalyst, the carbohydrate fraction is converted into water-soluble products under milder conditions than reported for similar reactions in the aqueous phase. The water-soluble products included monosaccharides, oligosaccharides, furfural, and 5-hydroxymethylfurfural (HMF).

Acid rain - Wikipedia
Acid rain - Wikipedia

Acidic water enters the plant and causes important plant minerals to dissolve and get carried away; which ultimately causes the plant to die of, lack of, minerals for nutrition. In major cases, which are more extreme, the same process of damage occurs as in minor cases, which is removal of essential minerals, but at a much quicker rate.

Using acids as HBDS, the ,desulfurization, efficiencies of some DES HBDs were as follows: p-toluenesulfonic acid (PTSA) > 5-sulfosalicylic acid > 4-aminosalicylic acid. A positive correlation was observed between DESs ,acidity, and ,desulfurization, efficiencies; i.e., DES with stronger ,acidity, exhibits higher ,desulfurization, capabilities .

Research Summary: Controlling Sulfur Oxides

Adding calcium hydroxide (Ca(OH)2) to the crushed coal ,causes, the organic sulfur in the coal to convert to calcium sulfite (CaSO3) when it is exposed to the microwave energy. The coal is then washed with water to remove the calcium sulfite and other impurities.

Because of the lower ,acidity, of FA (p K a1 = 3.8, carboxyl groups; 28 p K a2 = 8.6, phenolic groups 29) compared to that of SO 2 (p K a1 = 1.8, H 2 SO 3 30), deprotonated carboxylate in FA can indirectly interact with SO 2. The absorption of SO 2 results in an increase in the H + concentration, which triggers the protonation of COO − to COOH.

21/3/2016, · Sulfur, whose content in coal can be as high as 5%, is released as sulfur dioxide in the firing process. Capturing sulfur dioxide by passing the flue gas through an aqueous limestone slurry results in gypsum (calcium sulfate). Adding ,formic acid, to the ,desulfurization, cycle increases the efficiency of sulfur separation. 10.6.3 Well Acidifiers
