Pyrolysis is an important technol. to convert lignocellulosic biomass to a renewable liquid energy carrier known as pyrolysis oil or bio-oil. Herein we report the pyrolysis of pigeon pea wood, a widely available biomass in the Philippines, in a semi-continuous reactor at gram scale. The effects of process conditions such as temperature (400-600 闂佺娅ｉ悡?, nitrogen flow rate (7-15 mL min-1) and particle size of the biomass feed (0.5-1.3 mm) on the product yields were determined A Box-Behnken three-level, three-factor fractional factorial design was carried out to establish process-product yield relations. Of particular interest is the liquid product (bio-oil), of which the yield was shown to depend on all independent variables in a complex manner. The optimal conditions for highest bio-oil yield (54 weight% on dry feed intake) were a temperature of 466 闂佺娅ｉ悡? a nitrogen flow rate of 14 mL min-1 and a particle size of 1.3 mm. Validation of the optimized conditions proved that the average (n = 3) exptl. bio-oil yield (52 weight%) is in good agreement with the predicted value from the model. The properties of product oils were determined using various anal. techniques including gas chromatog.-mass spectrometry (GC-MS), gel-permeation chromatog. (GPC), NMR spectroscopy (13C- and HSQC-NMR) and elemental and proximate analyses. The bio-oils were shown to have low ash content (0.2%), high heating value (29 MJ kg-1) and contain high value-added phenolics compounds (41%, GC peak area) as well as low mol. weight aldehydes and carboxylic acids. GPC anal. indicated the presence of a considerable amount of higher mol. weight compounds NMR measurements showed that a large proportion of bio-oil contains aliphatic carbons (~60%), likely formed from the decomposition of (hemi)cellulose components, which are abundantly present in the starting pigeon pea wood. Subsequent preliminary scale-up pyrolysis experiments in a fluidized bed reactor (~100 gfeed h-1, 475 闂佺娅ｉ悡?and N2 flow rate of 1.5 L min-1) gave a non-optimized bio-oil yield of 44 weight%. Further fractionation and/or processing are required to upgrade these bio-oils to biofuels and biobased chems. In the experiment, the researchers used many compounds, for example, 3-Amino-2,6-dimethoxypyridine (cas: 28020-37-3Related Products of 28020-37-3).
3-Amino-2,6-dimethoxypyridine (cas: 28020-37-3) belongs to pyridine derivatives. The pyridine ring occurs in many important compounds, including agrochemicals, pharmaceuticals, and vitamins. Halopyridines are particularly attractive synthetic building blocks in a variety of cross-coupling methods, including the Suzuki-Miyaura cross-coupling reaction.Related Products of 28020-37-3
