Declassification and valorization of char materials from biofuels production

在本项目中，我们将与KBL环境有限公司合作，对作为从城市废物生产生物燃料的副产品的炭进行解密和增值的方法。虽然从城市废物生产生物燃料将固体废物从垃圾填埋场转移，但发现炭副产品含有高水平的萘，因此必须在1级垃圾填埋场进行处置。第一个目标是开发适当的稳定和固化技术，以确保萘不会从焦炭中浸出，从而可以以更低的成本在标准的第2类垃圾填埋场进行处置。其次，我们的长期目标是确定炭材料的替代用途，例如作为吸附剂从水中去除金属和有机污染物或清洁气化设施中的合成气。为此，广泛

In this project we will study, in collaboration with KBL Environmental, Ltd., methods to declassify and valorize char that is a byproduct of the production of biofuels from municipal waste. While the production of biofuels from municipal waste diverts solid waste from landfills, the char byproduct was found to contain elevated levels of naphthalene, such that it must be disposed of in Class 1 landfills. The first objective is to develop appropriate stabilization and solidification techniques to ensure that naphthelene does not leach out of the char, so that it can be disposed of in standard Class 2 landfills at a much reduced cost. Secondly, we aim in the longer-term to identify alternative uses for the char material, for example as a sorbent to remove metal and organic contaminants from water or to clean up syngas in gasification facilities. To do so, extensive
