Direct coal liquefaction: low temperature dissolution process

F Haghighat, A de Klerk - Energy & fuels, 2014 - ACS Publications
The front-end design of a direct coal liquefaction process for the conversion of lignite into
coal liquids by solvent extraction was investigated. The experimental work focused on …

Solvent–Coal–Mineral interaction during solvent extraction of coal

M Rivolta Hernández, C Figueroa Murcia, R Gupta… - Energy & …, 2012 - ACS Publications
Solvent extraction of coal is a coal-to-liquids conversion process whereby the organic matter
in coal is dissolved in a solvent to produce a substantially mineral matter free product. The …

[PDF][PDF] Peat and lignite leaching process with tetralin in autoclave to produce oil

T Depci, M Karta - Physicochemical Problems of Mineral …, 2018 - bibliotekanauki.pl
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 of coal

DC Figueroa - 2012 - era.library.ualberta.ca
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 …

Solvent extraction of coal: Influence of solvent chemical structure on extraction yield and product composition

M Rivolta - 2012 - era.library.ualberta.ca
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 …
