Study on Low Temperature Co-Carbonization of Coal and Algae

Abstract

Co-carbonization characteristics of long flame coal mixed with algae in different proportions were studied in a dry distillation equipment, and focusing on the coal tar of the product with GC-MS and FT-IR in order to investigate the changes in coal tar, The results show that the tar yield increases with the increasing of algae added, the light oil components of co-carbonized coal tar (with the optimal proportion 20:10 ) compared with conventional coal tar increased 29.55% while naphthalene content increased 9.15% and phenol content increased 23.93%. The algae sample played a role in hydrogen donating and the reactions involved opening-ring reaction, alkyl aromatic side chain reaction and condensation reaction, etc.

Optimization of Biochar Production by Co-Torrefaction of Microalgae and Lignocellulosic Biomass Using Response Surface Methodology

“…The combination of algal biomass with other materials or biomass residues has also been addressed by some authors who have studied co-pelletization of Chlorella vulgaris biomass with pine sawdust [12], co-carbonization of coal mixed with algae in different proportions [33], and co-liquefaction of Tetraselmis sp. biomass in the presence of ethylene glycol or isopropyl alcohol [34].…”
