Basic Equations

The high-temperature synthesis of silicon carbide (SiC) in an electro-thermal fluidized bed reactor (EFB) has advantages, in comparison with the production in resistance furnaces, in terms of specific energy consumption, productivity and the level of automation of the technological process. The basic equations of the fluidized-bed carbide formation process model are presented in the paper. The results of calculating the synthesis parameters of finely dispersed SiC in the stationary operation mode of the EFB reactor are also presented. The correspondence between the calculated and available experimental results on the output of the final product is shown.

High Temperature Operation

Owing to the high temperature inside a sulfur recovery unit (SRU) thermal reactor, detailed experimental measurements are difficult. In the author’s previous studies, several methods have been assessed to resolve the abnormality of the SRU thermal reactor under high temperature operation. This paper presents a new easier and more economical method. The effects of inlet air quantity and inlet O2 mole fraction on the combustion and fluid flow in a SRU thermal reactor are investigated numerically. The flow field temperature, S2 recovery, H2S mole fraction, and SO2 emissions are analyzed. This paper provides a guideline for adjusting the inlet air quantity and the inlet O2 mole fraction to reduce the high temperature inside a thermal reactor and to ensure an acceptable sulfur recovery.

The thermal fragmentation of salicylaldehyde was studied from two aspects. Firstly, the temperature dependence of the intensity of the thermolytic fragment molecular ions was observed at 11 eV in the effluent from a helium flow thermal reactor attached through a helium separator to the ion source of a mass spectrometer. Secondly, the products of the thermolysis on a semi-preparative scale under trapping conditions were determined by coupled gas chromatographic – mass spectrometric analysis.The title compound is the major primary thermal fragment in this study and was trapped with methanol as carboxymethylcyclopentadiene.
