Among the various problems the world is facing, two problems are addressed in this paper. On the one hand, biomass, the fourth largest and most important renewable energy option that can provide different forms of energy, is criticized because it competes, sometimes, with the food chain. On the other hand, the amount of municipal sewage sludge has continued to increase over the years, and its disposal remains a crucial point of discussion between urban planners, wastewater managers, and leaders of environmental protection. To address this problem, researchers are directing their focus toward alternatives to conventional biomass resources, such as organic wastes and residues. Thus, municipal sewage sludge is a likely candidate for energy and high-value added material production. Regarding this issue, one of the main methods proposed by researchers is the pyrolysis process. The aim of this paper is to review the research conducted on sewage sludge conversion through the pyrolysis process. After characterizing municipal sewage sludge, we present a summary of the sewage sludge pyrolysis process. Then, the effects of some of the most influential parameters are examined. The last main part of this work is dedicated to the nitrogen transformation pathway during this process.

用于生物燃料生产的城市污水污泥热解研究进展

在世界面临的各种问题中,本文要解决两个问题。一方面,生物质是第四大也是最重要的可提供不同形式能源的可再生能源选择,因为它有时与食物链竞争,因此受到批评。另一方面,多年来,城市污水污泥的数量一直在增加,其处置仍然是城市规划者,废水管理者和环境保护负责人之间讨论的关键点。为了解决这个问题,研究人员将注意力集中在传统生物质资源的替代品上,例如有机废物和残留物。因此,城市污水污泥可能是能源和高附加值材料生产的候选者。关于这个问题,研究人员提出的主要方法之一是热解过程。本文的目的是回顾通过热解过程进行的污水污泥转化研究。在表征市政污水污泥之后,我们对污水污泥的热解过程进行了概述。然后,检查一些最有影响力的参数的效果。这项工作的最后主要部分致力于此过程中的氮转化途径。
