“…Papers on co-conversion [17][18][19][20][21] report synergetic interactions between intermediate species derived from both plastic and biomass when co-pyrolysis or co-gasification are performed, thus improving the properties and quality of the final products. An explanation is the lower stability of biomass compared to plastics, which affects the radical degradation mechanism by promoting the degradation of polymers [22].…”

The addition of plastics to the steam pyrolysis/gasification of wood sawdust with and without a Ni/Al 2 O 3 catalyst was investigated in order to increase the production of hydrogen in the gaseous stream. To study the influence of the biomass/plastic ratio in the initial feedstock, 5, 10 and 20 wt. % of polypropylene was introduced with the wood in the pyrolysis reactor. To investigate the effect of plastic type, a blend of 80 wt. % of biomass and 20 wt. % of either polypropylene, high density polyethylene, polystyrene or a mixture of real world plastics was fed into the reactor. The results showed that a higher gas yield (56.9 wt.%) and a higher hydrogen concentration and production (36.1 vol.% and 10.98 mmol. H 2 g -1 sample, respectively) were obtained in the gaseous fraction when 20 wt. % of polypropylene was mixed with the biomass. This significant improvement in gas and hydrogen yield was attributed to synergetic effects between intermediate species generated via co-pyrolysis. TheNi/Al 2 O 3 catalyst dramatically improved the gas yield as well as the hydrogen concentration and production due to the enhancement of water-gas-shift and steam reforming reactions.Very low amounts of coke (less than 1 wt. % in all cases) were formed on the catalyst during reaction, with the deposited carbonaceous material being of the filamentous type. The Ni/Al 2 O 3 catalyst was shown to be effective one hydrogen production in the copyrolysis/gasification process of wood sawdust and plastics.

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.

“…Finally, the yield in water-free bio-oil also shows a synergy for all willow/PHB blends (Table 4). Here, however, the most pronounced synergy is obtained for the 2:1 willow/PHB blend reaching + 96.4% 9 . The maximum yield in water-free bio-oil (in absolute terms (Table 3)), on the contrary, is obtained during the co-pyrolysis of 3:1 willow/PHB, representing a yield of 45.63 m%.…”

Bio-oil obtained via flash pyrolysis shows potential to be applied as a renewable fuel. However, bio-oil often contains high amounts of water, which is a major drawback for its application. The influence of a biopolymer -polyhydroxybutyrate (PHB) on the pyrolysis of willow is investigated using a semicontinuous home-built pyrolysis reactor. The flash co-pyrolysis of willow/PHB blends (w/w ratio 7:1, 3:1, 2:1 and 1:1) clearly shows particular merits: a synergetic increase in pyrolysis yield, a synergetic reduction of the water content in bio-oil, an increase in heating value, and a production of easily separable chemicals. The occurrence of synergetic interactions is observed based on a comparison between the actual pyrolysis results of the willow/PHB blends, the theoretical pyrolysis results calculated from the reference pyrolysis experiments (pure willow and pure PHB) and their respective w/w ratio. The co-pyrolysis of 1:1 willow/PHB shows the best overall results.
