“…To reduce the energy costs and increase the target product output, we can use some equipment facilitating the efficient and even distribution of thermal energy through all of the reactor equipment to intensify chemical processes [13]. In particular, we have a hypothesis that heat exchange can be intensified through the use of agitators [14]. This hypothesis has not been confirmed for the pyrolysis of oil sludge decomposition products in any of the experimental research known to the authors.…”

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. Keywords: petroliferous sludge; hydrocarbon gas mix; n-butane; catalytic pyrolysis; experimental setup; reactor; agitator.

The study presents a simulation of pyrolysis reactors of various designs performed in the COMSOL Multiphysics software package. The non-isothermal flow (k–ε turbulent flow) module is used. The advantages this technique has over other commonly used ones are shown. The results indicate that under the same conditions, heating in sectional reactors is more intense. To achieve optimal results, the coolant flow rate in new reactors maybe by an order of magnitude less compared to the conventional design. The use of sectional reactors for multi-flow processing of hydrocarbon waste is advisable. Keywords: sectional reactor; pyrolysis; hydrocarbon waste; heat transfer; turbulent flow.
