High amounts of water present in bio-oil are one of the major drawbacks for its utilisation as a fuel. One technology that shows the potential to satisfy the demand for bio-oil with a reduced water content is the flash co-pyrolysis of biomass with polylactic acid, PLA. The influence of PLA on the pyrolysis of willow is investigated with a semi-continuous home-built pyrolysis reactor. Flash co-pyrolysis of willow/PLA blends (10:1, 3:1, 1:1 and 1:2) show synergetic interaction. A higher bio-oil yield and a lower water content as a function of the willow/PLA ratios are obtained. Among the tested blends, the 1:2 willow/PLA blend shows the most pronounced synergy: a reduction in the production of pyrolytic water of almost 28 %, accompanied by an increase of more than 37 % in the production of water-free bio-oil. Additionally, PLA shows to have a positive influence on the energetic value of the bio-oil produced and on the resulting energy recuperation.

“…The absorption intensity of CO2 derived from co-pyrolysis in the temperature region of HDPE decomposition was obviously higher than that released from EHL pyrolysis alone, which indicated the interaction between EHL and HDPE. The radicals from the HDPE decomposition were interacted with EHL, which results in the cracking reaction for oxygenated compounds (Marin et al 2002). This may have been responsible for the lower mass of residue derived from co-pyrolysis as mentioned in the TG analysis.…”

The thermal behaviors of enzymatic hydrolysis lignin (EHL), high-density polyethylene (HDPE), and their blend (50:50 wt.%) were revealed using thermogravimetric analysis coupled with Fourier transform infrared spectroscopy (TG-FTIR). A first-order reaction model (Coats-Redfern) and non-isothermal model-free method (Ozawa-Flynn-Wall) were applied to the TG experimental data to determine the pyrolysis kinetic parameters. The results showed that H2O and CO2 were first released from the EHL due to the degradation of the weakly linked side chains. The degradation of lateral chains, the breakage of aromatic series in the EHL structure, and the β scission of HDPE led to the formation of H2O, CO2, C=O, aromatics, alkanes, and alkenes. Low intensities of H2O, CO2, alkanes, and alkenes were also observed in the final pyrolysis stage due to the degradation of lignin groups. Interactions during co-pyrolysis were observed in the pyrolysis stages of 390 to 542 °C and 563 to 790 °C. The activation energy values of EHL, HDPE, and their blend obtained by the Coats-Redfern method were 48.0 to 94.4 kJ/mol, 230.2 kJ/mol, and 42.7 to 260.1 kJ/mol, respectively. When the Ozawa-Flynn-Wall method was applied, activation energy ranges of 121.4 to 243.7 kJ/mol, 143.5 to 335.9 kJ/mol, and 74.8 to 260.9 kJ/mol for EHL, HDPE, and their blend, respectively, were observed.

“…Thus, it is necessary to improve the quality of bio-oil. A promising way to increase the quality and yield of bio-oil is the co-pyrolysis of biomass/synthetic polymer mixtures [8][9][10][11][12]. The co-pyrolysis of mixtures of biomass and synthetic polymers has received attention in recent years [9].…”

“…Plastics with approximately 14 wt. %, such as PE (polyethylene) and PP (polypropylene), provide hydrogen to biomass during co-pyrolysis and improve bio-oil quality [9,[13][14][15][16]. Besides the co-pyrolysis of mixtures of biomass and synthetic polymers, other methods such as decarboxylation [17][18][19] and aqueous-phase reforming [20] can do the same.…”

Abstract:The doping of PP (polypropylene) with cotton straw improved the bio-oil yield, which showed there was a synergy in the co-pyrolysis of the cotton straw and PP at the range of 380-480 °C. In a fixed-bed reactor, model compounds and co-pyrolysis products were used for reactants of hydrodeoxygenation (HDO) over Ni-Mo/Al2O3. The deoxygenation rate of model compounds decreased over Ni-Mo/Al2O3 in the following order: alcohol > aldehyde > acetic acid > ethyl acetate. The upgraded oil mainly consisted of C11 alkane.
