The experimental research of n-butane pyrolysis using an agitator

Abstract

This research aims to improve the thermal processes of oil sludge treatment. The goal of this research is to determine the impact of the agitator on the output of hydrocarbon gas mixes and hydrogen during the catalytic pyrolysis of n-butane (C4H10), the product of stage one of the complex oil sludge treatment. To conduct the research, the authors developed a setup for the testing of a pyrolysis reactor with an agitator to assess its efficiency in terms of target n-butane breakdown products, namely hydrocarbon mixes and hydrogen. In this research, the authors used 70Ni–20Cu–10Al2O3 as a catalyst. The components of the obtained gas mix were analyzed using the chromatographic method. The results show that the use of the agitator during the catalytic pyrolysis of n-butane can increase the output of the target product. In particular, the hydrogen output increased by ~7.2% over the reaction period (12 hours) compared to the setup without an agitator. The authors determined that the optimal reaction time for the production of hydrogen and butane-hydrogen mix is 4 hours.

Effect of undissolved gas on fluid bulk modulus

“…These are just some of the methods of measuring the modulus of fluid volume elasticity. In each case, the choice of method depends on the properties and conditions of the experiment [5].…”

Numerical and Experimental Study of Heat Transfer in Pyrolysis Reactor Heat Exchange Channels with Different Hemispherical Protrusion Geometries

“…After releasing the required amount of heat energy, the heat carrier gas was directed to fume hood 6 through branch pipe 12 for further utilisation. The gaseous reaction products resulting from the thermal processing of organic raw material were directed through branch pipe 11 to hood 6 for further processing, in line with the complex technology of hydrogen production and hydrogen-containing mixtures presented in [27,28].…”

“…The intensification of heat and mass exchange processes is an urgent task in the production of hydrocarbon gas, which is required in the complex technology of the production of hydrogen mixtures and hydrogen by the thermal processing of organic raw materials, described in [27,28]. The technology involves two main stages.…”

The initial coolant temperature was 973 K with laminar and turbulent flows, and the reactor pressure was approximately equal to the atmospheric pressure (P0 = 0).…”
