This thesis is focused in hydrotreating and hydrocracking secondary refinery streams that have been previously hydrotreated (drastically reducing their heteroatom content) for their valorization both, alone and co-processed with alternative feeds from consumer waste such as HDPE and PP (since polyolefins represent the majority fraction of plastics in municipal solid waste, MSW) or plastic pyrolysis oil (PO) (in this case from HDPE waste). The challenge of the study has been to progress towards the Waste Refinery, obtaining high quality fuels (naphtha and diesel) as a product with the appropriate composition for their incorporation into the fuel pools in refinery, thus contributing to intensify the recovery of oil and the recycling of a fraction of municipal solid waste.
