“…2 shows the relationship of product yields with final temperature of pyrolysis at the heating rate of 10 K/min. The conversion ratio increases from 38 to 58 wt.% while the final pyrolysis temperature increases from 553 to773 K. The oil yield is 2.0 wt.% at the pyrolysis temperature of 553 K and appears to go through a maximum of 10 wt.% at the final [18][19][20][21], the yield of oil is rather lower, however, it is reasonable if the composition of the rice straw considered. Deducting the 10.1% moisture, 16.7% ash components and 50% gas production, there is only 24.3% left to convert to bio-petroleum.…”

“…5), the O-H stretching vibrations between 3300 and 3600 cm À1 indicate the presence of phenols and alcohols. The symmetrical and asymmetrical C-H stretching vibrations of aliphatic CH 3 and CH 2 groups (2800-3000 cm À1 ), together with C-H deformation vibrations between 1390 and 1475 cm À1 (1459 cm À1 ) indicate the presence of alkanes [20,21]. In addition, the bending vibration for CH 3 groups is located at 1375 AE 15 cm À1 [33].…”

“…Among the thermochemical processes [6], pyrolysis has received increasing attention [8]. A large number of research projects in the field of biomass pyrolysis have been performed [9][10][11][12][13][14][15][16][17][18][19][20][21][22][23] to obtain high quality liquid oil. The oxygen content in the rice straw bio-oil obtained through steam and static pyrolysis is in the range of 19.89-25.70 with heating value 28.52-25.58 MJ/kg [12].…”

Purpose Biochar has potential as a valuable tool for the agricultural industry with its unique ability to help build soil health, increase physical properties of soil, soil pH, organic carbon content, conserve water and mitigate drought, reduce GHG emission, conserve nutrients, decrease fertilizer requirements, sequester carbon, increase crop productivity and serve as a most preferred habitat for microbes. In this study, three perishable biomass wastes viz. Pea pod (Pisum sativum), cauliflower leaves (Brassica oleracea) and orange peel wastes (Citrus sinensis) were carbonized and characterized for differential application. Methods The biomass was subjected to carbonization at different temperatures from 100 to 600°C for 1 h. Biomass and biochar samples were characterized for proximate (M, VM, FC, Ash), ultimate (CHNS-O), biochemical properties (Ce, He, Li), thermo gravimetric analysis, pH, EC and bulk density. The biochars were also analyzed through SEM and FTIR for identification of pore size and functional groups. Results The char yield was high in cauliflower leaf (30.16 %), followed by orange peel (25.54 %) and pea pod (21.154 %) at 300°C. The total organic carbon (11.61 %), total negative surface anions (4.25 mmol H ? eq/g C) and water holding capacity (200 %) were high in pea pod biochar. The SEM images of biochar samples showed plane cleavage surfaces with broken edges. The surface functional groups of all the three biochar samples were hydroxyl, methyl, carboxylic and alkene groups. Conclusion The pea pod and cauliflower leaf biochar showed higher values of organic carbon, total surface anions, water holding capacity and mineral content and performed as best soil amendment than orange peel biochar. These biochar can be used as an effective medium for increasing soil carbon, irrigation efficiency and efficient disposal of agricultural waste-biomass.

Renewable Sustainable Energy 6, 053142 (2014); 10.1063/1.4900550 Pyrolysis kinetics of de-oiled cakes by thermogravimetric analysisDe-oiled cakes, a source of biomass in the form of agriculture residue, could be an ideal source for the production of bio-fuels that can be substituted with conventional fossil fuels. In this study, pyrolysis of mahua de-oiled cake (Madhuca indica) was carried in a semi-batch reactor at the temperatures of 350, 400, 450, 500, 550, and 600 C. The optimum temperature at which maximum yield of 41.36% (by weight) liquid product obtained was 550 C. Empirical formula of the bio-oil was established as CH 1.379 N 0.0576 S 0.004 O 0.614 . The thermal degradation of mahua de-oiled cake was studied in inert atmosphere from ambient temperature to a temperature of 600 C at a heating rate of 25 C min À1 . The chemical composition of bio-char was investigated by using SEM-EDX and its heating value was determined to be 26 MJ/kg. Characterization showed that the bio-oil obtained can potentially be valued as fuel and chemical feedstock.
