Volatiles and char combustion rates of demineralised lignite and wood blends

Oil production from mild pyrolysis of low-rank coal in molten salts media

“…Coal utilization process is a mature technology yet still attractive to be researched. The recent researches on coal are focused on how to utilize low-rank coal effectively since about half of the coal reserves are in the low-rank state (lignite and sub bituminous) [2][3][4][5][6][7][8][9][10].…”

Production of diesel-like fuel from waste engine oil by pyrolitic distillation

“…Many research works addressed the utilization of waste oils that are of lubricating oils originated from crude oil [3] and biomass origin waste oils for the case of diesel engine applications [4][5][6] as sources of energy. The gaseous yield from steam gasification and pyrolysis of biomass have been investigated experimentally, the results of steam gasification have been compared to that of pyrolysis [7][8][9][10][11][12][13]. The temperature range investigated at elevated temperature in the range of 550-1000°C.…”

Effects of coal drying on the pyrolysis and in-situ gasification characteristics of lignite coals

“…Stochastic simulations results fitted well with the experimental yields of CH 4 and other hydrocarbons. Utilization of lignite coal were novelly applied in the fields of carbon fuel cell [6] and co-combustion/co-gasification of coal and biomass [7,8]. Nevertheless, lignite coals were usually dried in an oven at 105°C under nitrogen before the thermal reaction experiments at high temperatures in most of these researches [3][4][5][6][7][8], and the effects of water in coals on the reaction characteristics were not considered.…”

As a young coal, lignite coal usually contains high volatiles (30-50 wt.%, dry basis) and moisture contents (20-55 wt.%, as received basis), [9][10][11][12] and the moisture contents in some lignite coals can even reach $70 wt.% (as received basis) [13].…”
