超音波ソノケミストリーおよび気液平衡特性を併用した重質系燃料の改質に関する研究 : 定在波型ソノケミカル反応場における重質油の軽質化(熱工学,内燃機関,動力など)

Abstract

In this research, the objective of our research was to convert heavy fuels or solid fuels into lighter liquid fuels with better fuel properties. We have proposed the fuel reformulation technique through an ultrasonic Sonochemistry application. However, we could get little volume of the improved fuel. Therefore, we need a larger apparatus to put the fuel reforming by ultrasonic waves into practical use. As the first step toward the introduction of the new fuel reforming method by Sonochemistry into industry, we set up a long cylindrical apparatus in direction of the ultrasonic waves which improves the standing waves. And then, we examined the influence on the reforming effect of the fuel containing one single component by liquid level change. We obserbed that the reforming efficiency was dependent on the liquid level, the efficiency becomed higher under the resonant state of the ultrasonic waves. We concluded that the collapse intensity of the bubbles was intensified due to formation of the standing wave in the resonance condition.
