“…The gas yield is calculated by difference. 4 The presence of crotonic acid in the pyrolytic gasses was already observed in this research with the aid of TG/MS (m/z 39, 41, 68, 69, and 86). The entire compositional analysis of the bio-oil and crystals will be discussed in more detail in a future article.…”

“…The pyrolysis of pure PHB, on the other hand, only results in the production of such crystals. The crystals contain no water and are characterised with the aid of GC/MS as crotonic acid or butenoic acid 4 . Table 2 summarises the pyrolysis yields and efficiencies of the flash (co-)pyrolysis of pure willow, pure PHB and willow/PHB blends with a w/w-ratio of 7:1, 3:1; 2:1 and 1:1; performed with the semicontinuous home-built pyrolysis reactor.…”

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.

“…The development of new and renewable energy sources (including biofuels) is the key to change [1]. The flash pyrolysis of biomass is a promising route with regard to the production of solid (char), liquid (bio-oil) and gaseous materials as possible alternate energy sources [2][3][4]. In order to maximise the bio-oil yield, process conditions should be: low temperature, high heating rate and short gas residence time [5,6].…”

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 results of this experiment showed that the liquid yield product reached a higher of 68% by employing higher heating rate of 300 ˚C min -1 under temperature of 550 ˚C and particle size range of 0.6 -1.25 mm. The proportion liquid products depends very much on the pyrolysis technique used and on the reaction parameters [11].…”

Effect of blending ratio to the liquid product on co-pyrolysis of low rank coal and oil palm empty fruit bunch

et al. 2018

The utilization of Indonesia low rank coal should be maximized, since the source of Indonesia law rank coals were abundant. Pyrolysis of this coal can produce liquid product which can be utilized as fuel and chemical feedstocks. The yield of liquid product is still low due to lower of comparison H/C. Since coal is non-renewable source, an effort of coal saving and to mitigate the production of greenhouse gases, biomass such as oil palm empty fruit bunch (EFB) would added as co-feeding. EFB could act as hydrogen donor in co-pyrolysis to increase liquid product. Co-pyrolysis of Indonesia low rank coal and EFB were studied in a drop tube reactor under the certain temperature (T= 500 ˚C) and time (t= 1 h) used N2 as purge gas. The effect of blending ratios of coal/EFB (100/0, 75/25, 50/50, 25/75 and 0/100%, w/w %) on the yield and composition of liquid product were studied systematically. The results showed that the higher blending ratio, the yield of liquid product and gas obtained increased, while the char decreased. The highest yield of liquid product (28,62 %) was obtained used blending ratio of coal/EFB = 25/75, w/w%. Tar composition obtained in this ratio is phenol, polycyclic aromatic hydrocarbons, alkanes, acids, esters.
