“…The refractive index and densities were measured (Table 7). The produces from test PE-CaO-N2 and PE-CaO-CO2 had a higher non-measurable viscosity and density so they were measured at 50 • C. These results could not be compared directly with other research works because of the different used methodologies [8,9,12,13,[36][37][38][39][40][41]. Table 8 shows different results obtained by other researchers and through our work.…”

Direct Polypropylene and Polyethylene Liquefaction in CO2 and N2 Atmospheres Using MgO Light and CaO as Catalysts

The polyolefin to lighter molecules reaction reduces the waste-plastic residues to produce fuels and valuable chemicals. Commercial MgO light and CaO were used as catalysts for the direct polyethylene and polypropylene liquefaction in N2 or CO2 atmospheres. The products were analyzed (ATR-FTIR, GC-FID/TCD, GC-FID, density, refractive index). The use of MgO light and CaO improved the conversion of propylene and ethylene to liquid products. In addition, low gaseous and solid products yields were obtained. A good production of organic liquids in the gasoline, diesel and kerosene boiling range was obtained. The use of CO2, in some cases, led to a higher conversion into liquids compared with the reactions performed in the N2 atmosphere. In addition, the use of the CO2 atmosphere led to a higher content of products with a boiling range in the diesel and kerosene ranges.

“…Other works were performed by the pyrolysis reaction. Compared to the direct liquefaction, this type of reaction led to lower yields to liquids (Table 8) [8,9,12,13,[36][37][38][39]. In addition, no direct liquefaction under the CO 2 atmosphere was found in the literature.…”

“…The calrorific value of polypropylene is 46.4 MJ/kg as par with diesel having calorific value at 43.0 MJ/kg [37]. A number of reports on the possibilities of deriving fuel from plastic using different process conditions and catalyst has been studied [38][39]. In this work, an attempt has also been made to explore the potential of PyO-PP and PyO-POPP40 pyrolysed oil obtained from neat PP and POPP40 biocomposite to be used as fuel or additive.…”

“…Despite hydrogenation of LCO potentially increasing gasoline yield, there is still room for improvement of gasoline quality. After hydrogenation, hydro-LCO contains a considerable amount of naphthenoaromatics such as tetralin, which are superior hydrogen donors that have been demonstrated by many studies. − When contacting with heavy oil, these hydrogen donors would rather induce hydrogen transfer reactions and generate 2-ring aromatics into LCO fraction than open naphthenic rings and generate alkylbenzenes into gasoline fraction . Therefore, if LCO is directly mixed and hydrogenated with residue or gas oil, and then returns back to FCC unit together, conversion of hydro-LCO would still be low.…”

Light cycle oil (LCO) from fluid catalytic cracking (FCC) was treated by selective hydrogenation and then cracked in a FCC apparatus. Compared with LCO, hydrogenated LCO (hydro-LCO) exhibited remarkable FCC performance, recording with that 50.83 wt % hydro-LCO was converted into gasoline fraction. This is attributed to the reduction of aromatics in hydro-LCO, especially for the multiring aromatics. After hydrogenation, the amount of multiring aromatics significantly decreased from 63.2 to 9.5 wt %, while naphthenoaromatics (including indans, tetralin, and indenes) increased from 8.8 to 34.2 wt %. In accordance with the experimental results and theoretical analysis of LCO reaction characteristics, a synergistic process for LCO efficient conversion to high octane number gasoline was proposed, and simulation experiments were carried out. The results show that, compared with routine FCC, 20 wt % higher conversion and 16 wt % more gasoline could be obtained. Moreover, gasoline from synergistic process exhibited decreased sulfur and olefins, but increased aromatics, and thereby improved octane number. These findings indicate that the proposed synergistic process could be an effective option for producing gasoline with high octane number.
