A detailed molecular fingerprint of raw pyrolysis oil from plastic wastes is a new research area. The present study focuses for the first time on chemical recycling marine litter; we aim to chemically characterize obtained and its distillates (virgin naphtha gasoil) via GC-MS FT-IR. For all samples, more than 30% detected compounds were identified. 2,4-dimethyl-1-heptene, marker PP pyrolysis, m...

The association between exposure to naphtha and neurobehavioural measures was examined prospectively over one year among workers employed at an automotive plant that used naphtha to calibrate fuel injectors. The neurobehavioural tests included those that assess mood, basic intelligence, and functioning of the cerebral frontal lobes and limbic system and were designed so that acute, reversible, ...

Introduction An aromatics complex is a combination of process units that can be used to convert petroleum naphtha and pyrolysis gasoline (pygas) into the basic petrochemical intermediates: Benzene Toluene and Xylenes (BTX). Benzene is a versatile petrochemical building block used in the production of more than 250 different products. Ethylbenzene, cumene, and cyclohexane are the most important ...

This work investigated the steady state and dynamic simulation of a fixed bed industrial naphtha reforming reactors. The performance of the reactor was investigated using a heterogeneous model. For process simulation, the differential equations are solved using the 4th order Runge-Kutta method .The models were validated against measured process data of an existing naphtha reforming plant. The r...

Pyrolysis of a post-consumer plastic waste stream (DKR-350) has been performed at laboratory scale in fixed-bed reactor 500 °C. DKR-350 is complex mixture plastics comprising polyethylene, polypropylene, polystyrene, polyethylene terephthalate, clogged materials, multilayer flexibles, together with considerable amounts biogenic and inorganic residues halogens. The influence different washing pr...

The run length of cracking furnaces is limited by the formation of coke on the internal skin of the reactor tubes. The reaction mechanism of thermal cracking of hydrocarbons is generally accepted as free-radical chain reactions. On the basis of the plant output data and the insight in the mechanisms for coke formation in pyrolysis reactors, a kinetic model describing the coke formation has been...

Sustained increase in plastic use has placed a significant burden on waste disposal infrastructure. Pyrolysis is the process of decomposing high-molecular-weight compounds by heating plastics at 500–1000 °C without oxygen. This considerably reduces greenhouse gas emissions and high alternative energy effect (0.57 TOE ton−1). After separation process, oil produced pyrolysis (C5–C20) can yield na...
