Instead of directly burning a lignite having low calorific value and peat, the Elbistan lignite (L) and the Adiyaman peat (P) were mixed and leached in an autoclave to obtain an oil to …
Modelling of solvent extraction was studied using 1, 2, 3, 4–tetrahydronaphtalene (tetralin) and Poplar coal (lignite). A kinetic model was developed taking into account temperature …
In recent years the need for new carbon sources to supplement crude oil for the production of fuels and chemicals, again focused on coal as suitable candidate. Old and new …
The aim of the first part of this study was to investigate the extractability of a South African bituminous (Waterberg) coal using phenol as a solvent at 300 C, 320 C, 340 C, and 360 C …
