Microwave prolysis is an eco-friendly system that has been widespread especially in recent years.
In this process, the waste oil meets a bed with high microwave suction power in a neutral atmosphere. By microwave heat these waste oil molecules are separated into smaller hydrocarbon oil, gas and coal, and the main phase of the prolapse process is completed. The waste fat is then prolysed through a primer prolysis process. The waste oil performs the first crack and the resulting prolysis becomes volatile. This volatile prolysis then enters into a second process in which serial and parallel secondary reactions can take place, which can lead to the formation of condensable combustible hydrocarbons and higher quantities of non-condensable gaseous hydrocarbons, in addition to charcoal products. Homogeneous or heterogeneous secondary reactions may occur, such as secondary cracking. These are aromatization, reforming, deoxygenation, dehydrogenation, condensation and carbonisation.
