of SO2 and O2 through a number of catalyst stages to form SO3. Commercial O2 is fed downstream of the catalyst in the first stage into the gas mixt., and also into the last stage upstream of the catalyst. Downstream of the catalyst in each stage, the gas mixt. is cooled by a ...
申请(专利权)人: UNIVERSITY OF SOUTHERN CALIFORNIA 发明人: JM Whelan 被引量: 3 摘要: A process for the oxidation of sulphur dioxide to sulfur trioxide in the presence of elemental nitrogen with minimal oxidation thereof which comprises combining the sulfur dioxide with a predetermined amount ...
Methanesulfinic acid (MSIA) is an important intermediate in the oxidation of dimethyl sulfide (DMS) in the marine boundary layer. The oxidation of MSIA by ozone in the gas phase to form methanesulfonic acid (MSA) was investigated using theoretical calcul
per unit of time. The initial hot gas mixt. is pref. obtd. from a sulphur burner, and contains min. 8 vol.% SO2. The conversion to SO3 is min. 98 wt.%. Pref. process, a simple absorption plant is used; and up to 50 wt.% of the catalyst is removed in the first stage and...
from a sulphur burner, and contains min. 8 vol.% SO2. The conversion to SO3 is min. 98 wt.%. Pref. process, a simple absorption plant is used; and up to 50 wt.% of the catalyst is removed in the first stage and replaced by a non-catalyst. Used for mfr. of SO3 and H2SO4...
of SO2 to SO3 at the usual SO2 concns. but can use SO2 and/or O2 contents as high as 100%. The appts. consists of an upright cylinder, through which a number of tubes pass, (some of) which are (partly) filled with a suitable catalyst, whilst groups of tubes can be charged ...

In recent years, a number of patent applications for mercury oxidation catalysts have appeared. A brief summary of their main features will be presented as well. 2. Operation Condition and Constraints of Hg Oxidation Catalysts in Flue Gases All fuels, including renewables such as wood or gaseous...
With the increase of potential to 0.9 V, the number of by-products found after 24 h included dihydroxyacetone, glyceraldehyde, tartronic acid, formic acid, mesoxalic acid and lactic acid. At a potential of 1.1 V for which 62% conversion was achieved, glyceraldehyde, mesoxalic and tartronic ...
Modelling and Multi-Objective Optimization of the Sulphur Dioxide Oxidation Process. Processes 2021, 9, 1072. https://doi.org/10.3390/ pr9061072 Abstract: Sulphuric acid (H2SO4) is one of the most produced chemicals in the world. The critical step of the sulphuric acid production is the ...
