| dc.description.abstract | 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. Therefore, to make pyrolytic carbon viable for applications, further 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. | en_US |

Paralelamente, la demanda de muchas formas de carbono está en aumento. Por lo tanto, para que el carbono pirolítico sea viable para aplicaciones, son necesarios pasos de procesamiento adicionales. En esta tesis, se investigaron los carbonos pirolíticos derivados de la pirólisis de poliolefina (PyCP) y gas metano (CMP). Se utilizaron métodos de separación como flotación, velocidad de sedimentación y separación magnética húmeda para la purificación de PyCP. La flotación inversa de PyCP mostró algunos resultados prometedores para la mejora del grado del carbono. CMP se considera la muestra de carbono pirolítico más pura y fina recibida. Se realizaron pruebas de aglomeración en CMP para mejorar su transportabilidad y aplicabilidad. Los aglutinantes de lignosulfonato se consideraron los mejores en base a los resultados de las pruebas de alta resistencia a la compresión en comparación con otros aglutinantes. Los carbones purificados del PyCP tienen numerosas aplicaciones potenciales, como la mejora de las superficies de carbono. | es |
