Abstract

In this paper, the microwave plasma gasification of a variety of solid fuels is experimentally investigated. The produced syngas is analyzed by thermochemical methods and gasification performance is evaluated. The solid fuel, air, and electrical power are the inputs while the syngas and ash are the outputs of the system in the process. The solid fuels are examined by proximate and ultimate analysis. The air is supplied to the reactor at 100?sL/min steadily and the supplied amount is determined regarding to gasification duration. Microwave power is adjusted between 3 and 6?kW. The syngas temperature is measured by B type thermocouples and the syngas temperature varies between 621 and 1204?°C. The produced syngas is examined by MRU gas analyzer. The syngas production rate is between 2.31 and 2.57?g/s. Process energy efficiency, system energy efficiency and hot gas energy efficiency of the microwave plasma gasification are estimated for each operation by using these measured parameters. The process and system energy efficiency are between 36 and 86% and between 27 and 61% respectively. The hot gas energy efficiency is between 34 and 68%.

微波等离子体气化多种燃料用于合成气生产

本文对微波等离子体气化多种固体燃料进行了实验研究。用热化学方法对所制合成气进行了分析，并对其气化性能进行了评价。在这个过程中，固体燃料、空气和电力是输入，而合成气和灰是系统的输出。固体燃料通过近似分析和最终分析进行检验。空气被供应到反应堆的温度是100?sL/min稳定，供给量根据气化持续时间确定。微波功率在3到6kw之间调节。合成气温度由B型热电偶测量，合成气温度在621 ~ 1204℃之间变化。生成的合成气用MRU气体分析仪进行检测。合成气产率在2.31 ~ 2.57 μ g/s之间。利用实测参数对微波等离子体气化各操作的过程能效、系统能效和热气体能效进行了估算。过程和系统的能源效率分别在36% ~ 86%和27% ~ 61%之间。热燃气能源效率在34% ~ 68%之间。

期刊介绍： Publishing original papers on fundamental and applied research in plasma chemistry and plasma processing, the scope of this journal includes processing plasmas ranging from non-thermal plasmas to thermal plasmas, and fundamental plasma studies as well as studies of specific plasma applications. Such applications include but are not limited to plasma catalysis, environmental processing including treatment of liquids and gases, biological applications of plasmas including plasma medicine and agriculture, surface modification and deposition, powder and nanostructure synthesis, energy applications including plasma combustion and reforming, resource recovery, coupling of plasmas and electrochemistry, and plasma etching. Studies of chemical kinetics in plasmas, and the interactions of plasmas with surfaces are also solicited. It is essential that submissions include substantial consideration of the role of the plasma, for example, the relevant plasma chemistry, plasma physics or plasma–surface interactions; manuscripts that consider solely the properties of materials or substances processed using a plasma are not within the journal’s scope.
