Carbonisation of bagasse in a fixed bed reactor: influence of process variables on char yield and characteristics

Review Paper: The Fundamentals of Biochar as a Soil Amendment Tool and Management in Agriculture Scope: An Overview for Farmers and Gardeners

“…[63] explored the effect of heating rate; maximum treatment temperature and sweep gas flow rate in a 23 factorial scheme trial and found that temperature was the leading parameter. Comparable or similar temperature-induced yield reductions have been stated for pyrolysis of animal wastes [64] [65], sunflower cake [66], rapeseed [67], cottonseed cake [68], pinewood bark [69], and sugarcane bagasse [70]. Increased heating rate, increased sweep gas streamor flow rate and reduced particle size all lead to reduced biochar production [71].…”

On the (Pseudo) Capacitive Performance of Jack Fruit Seed Carbon

“…Consequently the type and % of the constituents is expected to influence the electrochemical parameters and hence ultimate elemental analysis has been conducted on the JFSC. Added to the above, it is well known that the heating rate controls the rate of volatile evolution from the biomass during pyrolysis and so slow heating and longer volatile times would promote high char yield [48]. This fact is obvious in the present work that the pyrolysis of JFS yielded a mass that was analyzed to contain 71.4 wt% carbon with certain amount of H (1.476%), S (0.836%) and N (3.821%) also existing in the JFSC, but the total amount of these elements in weight is less than 100%.…”

The Influence of Biochar Production on Herbicide Sorption Characteristics

“…However, biochars, unlike commercial fertilizers, are not precisely defined materials and vary widely in properties depending on organic material source and manufacturing process (Karaosmanoglu et al, 2000;McHenry, 2009;Sohi et al, 2010). Increasing pyrolytic temperature decreases biochar recovery but increases C concentration of the char compared with char recovered at lower temperatures (Daud et al, 2001;Katyal et al, 2003). For example, as temperature increased from 300 0 to 800 0 C, biochar C content increased from 56 to 93% whereas biochar yield decreased from 67 to 26% (Okimori et al, 2003).…”

“…For example, as temperature increased from 300 0 to 800 0 C, biochar C content increased from 56 to 93% whereas biochar yield decreased from 67 to 26% (Okimori et al, 2003). Other pyrolytic parameters, such as sweep gas flow, can influence biochar particle size with higher flows reducing the particle size but increasing heating values (Katyal et al, 2003;Demirbas, 2004). Biochar also can be influenced by reactor design and other reaction parameters including heating rate, residence time, pressure, and catalyst used.…”
