Waste oils coprocessed with plastics

In addition to the above-mentioned catalytic processes, there are some other related technologies wherein the catalytic cracking of plastic wastes is combined with the coprocessing of other substances, mainly coal and petroleum feedstocks (lube oil, LCO, VGO) or even a solvent. Hereafter, these technologies are explained more in detail. 

This chapter deals exclusively with tertiary recycling by pyrolysis and catalytic cracking of plastics waste alone and by coprocessing with petroleum residue or heavy oils to... 

Coprocessing of waste plastics with heavy petroleum fractions have considerable interest in feedstock recycling. In this study, we aimed to investigate the processing of municipal waste plastics (MWP) in presence of conventional and non-conventional catalysts in a refinery stream. For this purpose, the hydrocracking of MWP in vacuum gas oil (VGO) over metal loaded active carbon and conventional acidic catalysts (HSZM-5, DHC-8) was carried out to obtain liquid fuel. 2 refs. 

This section deals with the economic evaluation of the conversion of mixed plastics waste (MPW) into synthetic crude (syncrude) oil and coprocessing of MWP with vacuum residue into syncrude. In their feasibility study, Ali and co-workers considered the process technology developed by Veba Oel AG of Germany the Veba Combi-Cracking (VCC) option for the processing of MPW [31], The process data and economic data were taken mainly from Dijkema and Stougie [32] and Huffman and Shah [33] for this study. All the cost data were translated to represent the economic analysis for Saudi Arabian conditions.
