Research output: ThesisMaster's Thesis


The generation of pyrolytic carbons through pyrolysis is rising due to energy recovery in the form of pyrolysis gas and pyrolysis oil from various waste sources, as well as the production of hydrogen from methane decomposition. In parallel, the demand for many forms of carbon is on the rise. In order to make pyrolytic carbon viable for further applications, processing steps are necessary. In this thesis, pyrolytic carbons derived from the pyrolysis of polyolefin (PyCP) and methane gas (CMP) were investigated. Separation methods such as flotation, settling velocity, and wet magnetic separation were used for the purification of PyCP. Reverse flotation of PyCP showed some promising results for carbon grade improvement. CMP is considered the purest and finest of all pyrolytic carbon samples received. Agglomeration tests were performed on CMP to improve its transportability and applicability. Lignosulfonate binders were considered the best based on high compressive strength test results in comparison with other binders. There are many potential applications for the purified carbons of the PyCP, such as improving the carbon surfaces.
