Catalytic characteristics of the pyrolysis of lignite over oil shale chars

Valorization of Mexican biomasses through pyrolysis, combustion and gasification processes

“…The two last peaks (3rd and 4th in Table 2) were related to the decomposition of lignin and cellulose by disintegration of monomeric phenols, aromatic rings and piranose structures present in their structures [77]. These peaks could also be related to the high mineral content in the samples, such as Ca, Mg and K, being 60,295, 5865 and 5593 ppm, respectively [78][79][80]. Moreover, the differences in the maximum weight loss rate (Pinus sawdust > Castor stem > Castor husk > Agave bagasse) can be related to the volatile matter content [76,[81][82][83].…”

Catalytic pyrolysis of lignite with clay catalyst activated with spent pickling liquor

“…Pyrolysis is an important technology for the clean and effective utilization of low-rank coal. [4][5][6] In order to obtain various value-added products such as synthetic engine fuels and fine chemicals from low-rank coals, the most appealing method is catalytic pyrolysis. 5,7 The use of a catalyst in the pyrolysis of coal results in the creation of oil products with higher quality, lower density, and less pollutant content.…”

“…In order to find solutions for such problems, it is essential that the low‐rank coals are converted by means of a suitable high conversion technology such as catalytic pyrolysis into higher value‐added products (liquid fuels, fine chemicals, etc.). Pyrolysis is an important technology for the clean and effective utilization of low‐rank coal 4–6 . In order to obtain various value‐added products such as synthetic engine fuels and fine chemicals from low‐rank coals, the most appealing method is catalytic pyrolysis 5,7 .…”
