Abstract

The thermal decomposition of acetylene to hydrogen and acetylene soot was studied, and the results of this study are presented. The experiments on acetylene decomposition were performed in a modified internal combustion engine (ICE) and in a flow-type reactor with external heat supply at a constant temperature (1000 ± 10°C). The experiments were performed without any oxidant additions. In the experiments with ICE, the engine work on acetylene was shown to be possible, and the composition of the gaseous reaction products was determined. In the experiments with a flow-type reactor, the effects of pressure in the reactor, acetylene flow rate, and the presence of a tungsten gauze in the working zone of the reactor on the degree of acetylene decomposition and the composition of gaseous reaction products was determined. Some properties of soot were analyzed: specific surface area, average particle size, bulk density, and combustion heat.

乙炔分解为氢和碳：内燃机实验和流动反应器实验

摘要

研究了乙炔热分解为氢和乙炔烟灰，并给出了研究结果。乙炔分解的实验是在改进的内燃机（ICE）和具有外部供热的流动型反应器中进行的，温度恒定（1000±10°C）。进行实验时不添加任何氧化剂。在使用ICE进行的实验中，表明可以在乙炔上进行发动机工作，并确定了气态反应产物的组成。在流式反应器的实验中，反应器中的压力，乙炔流速以及反应器工作区中钨丝的存在对乙炔分解程度和气态反应产物组成的影响为决定。
