Nowadays, the thermal and catalytic decomposition of plastic wastes by pyrolysis is one best alternatives to convert these into quality fuel oils, thus replenishing some petroleum resources. This work studied polyethylene film waste from remaining organic fraction on different catalysts under dynamic operating conditions in a batch reactor. These have been characterized through isotherms adsorp...

Pyrolysis of plastic waste allows to produce liquid fractions, but their molecular weight distributions are typically very large whereas it would be interesting focus on light hydrocarbons. In this study, the pyrolysis polypropylene (PP) was investigated using a semi-batch, vertical glass reactor heated at 480 °C equipped with reflux condenser. The performed and without temperature top condense...

Direct industrial application of x-ray absorption spectroscopy is demonstrated by research in catalysis (CO/H2 and naphtha reforming) and corrosion protection.

the paper introducedeffects of modified pyrolysis tar on flue gas desulfurization. this experiment selected the pyrolysis tar as the raw material, researched the effects on desulfurization performance under different modification solution, concentration, solid liquid ratio of pyrolysis tar and modified solution, calcination temperature and calcination time by 16 group orthogonal experiments. th...

Substitution of hazardous substances against less hazardous ones is a central requirement of the European Chemical Regulation REACH (European Regulation 1907/2006/EC). Hazardous substances emitted from products may not only affect the worker; drift off and distribution in the environment may finally result in exposure of the general population. This potential threat to health is covered by the ...

This paper describes the applicability of a Hg-electroplated-Pt ultramicroelectrode in the quantification of elemental sulphur in naphtha samples by square-wave voltammetry. A reproducible deposition methodology was studied and is reported in this paper. This methodology is innovative and relies on the quality of the mercury stock solution to obtain reproducible surfaces required for the analyt...

In thermal cracking plants, it is desired to apply an optimal temperature profile along the reactor to minimize the operation cost. In this article a simulator is developed by the use of a mathematical model, which describes the static operation of a naphtha thermal cracking pilot plant. The model is used to predict the steady state profiles of the gas temperature and product yields. Using ...

Biomass was subjected to conventional and microwave pyrolysis, to determine the influence of each process on the yield and composition of the derived gas, oil and char products. The influence of pyrolysis temperature and heating rate for the conventional pyrolysis and the microwave power was investigated. Two major stages of gas release were observed during biomass pyrolysis, the first being CO...
