Many thermal processes have been developed in order to eliminate the municipal solid wastes or produce energy from them. These processes include a wide range of applications from the simplest burning system to plasma gasification. Plasma gasification is based on re-forming of molecules after all molecules convert to smaller molecules or atoms at high temperatures. In this work, the production of fuel gas is aimed by plasma gasification of municipal solid wastes in high temperatures. Because of this, a plasma reactor of the capacity of 10 kg h−1 was designed which can gasify municipal solid wastes. Plasma gasification with and without steam and oxygen was performed in temperatures of 600, 800, 1000, 1200, 1400 and 1600 °C in the reactor. A gas mixture containing methane, ethane, hydrogen, carbon dioxide and monoxide, whose content varies with temperature, was obtained. It was found that plasma gasification (or plasma pyrolysis, PG), plasma gasification with oxygen (PGO) and plasma gasification with steam (PGS) were more prone to CO formation. A gas product which was consisted of 95% CO between 1200 and 1400 °C was produced. It was observed that a gas with high energy capacity may be produced by feeding oxygen and steam into the entrance of the high temperature region of the reactor.

等离子弧介质中城市固体废物的气化

为了消除城市固体废物或从中产生能量，已经开发了许多热工艺。这些工艺包括从最简单的燃烧系统到等离子气化的广泛应用。等离子气化是基于所有分子在高温下转化为更小的分子或原子后分子的重新形成。在这项工作中，燃气的生产旨在通过在高温下对城市固体废物进行等离子体气化。因此，设计了一个容量为 10 kg h-1 的等离子体反应器，可以气化城市固体废物。在反应器中在 600、800、1000、1200、1400 和 1600 °C 的温度下，使用和不使用蒸汽和氧气进行等离子体气化。含有甲烷、乙烷、氢气、二氧化碳和一氧化碳的气体混合物，其含量随温度变化，得到。发现等离子气化（或等离子热解，PG）、等离子氧气气化（PGO）和等离子蒸汽气化（PGS）更容易形成一氧化碳。在 1200 到 1400 °C 之间产生了由 95% CO 组成的气体产品。观察到，通过将氧气和蒸汽加入反应器高温区的入口，可以产生具有高能量容量的气体。
