Lignin recovery, Biochar Production and Decolourisation of Coir pith Black Liquor

  title={Lignin recovery, Biochar Production and Decolourisation of Coir pith Black Liquor},
  author={I. S. Bright Singh and Girindran Rojith},
Coir pith black liquor obtained as a dark brown filtrate from oxidative delignification needs to be decolourised before releasing to open environment. From this liquor industrially valuable lignin was recovered using acid precipitation method. ‘Biochar’ was produced by slow pyrolysis of coir pith at 500 o C and 600 o C. Water holding capacity and pH of the biochar were estimated. CHNS analysis was carried out to identify the nutrient profile. Structural characterization was done using FTIR and… Expand

Lignin recovery from brewer’s spent grain black liquor
Abstract The present study describes the precipitation of lignin by acidification of a black liquor (pH 12.56 and 12.44 g/l soluble lignin) produced by soda pulping of brewer’s spent grain. SulfuricExpand
Characteristics of lignin obtained from steam-exploded softwood with soda/anthraquinone pulping
Lignins were obtained from a mixture of softwood sawdust using a hydrolytic pretreatment and a subsequent soda-anthraquinone delignification/pulping stage. Their potential uses and the effect of theExpand
Removal of phenols from water and petroleum industry refinery effluents by activated carbon obtained from coconut coir pith
Coir pith obtained from the coir industry as waste biomass was used to prepare activated carbon by chemical activation using phosphoric acid (H3PO4). The influences of activation temperature andExpand
Characterization of biochars produced from cornstovers for soil amendment.
Since the CEC of the fast-pyrolytic cornstover char can be about double that of a standard soil sample, this type of biochar products would be suitable for improvement of soil properties such as CEC, and at the same time, can serve as a carbon sequestration agent. Expand
Biochar as a precursor of activated carbon
Thermogravimetric study showed that when potassium hydroxide to biochar mass ratio was more than one, the weight loss decreased, and Fourier-transform infrared spectroscopy analysis showed development of aromatization in the structure of activated carbon. Expand
