Study on Low Temperature Co-Carbonization of Coal and Algae
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.
