Novel Use of Residue from Direct Coal .

Direct coal liquefaction residue (DCLR) is, commonly, designed to be used as a feed stock for gasification or combustion. Use of DCLR as a value added product is very important for improving overall economy of direct coal liquefaction processes. This study shows that the DCLR may be used as a pavement asphalt modifier. The modification ability is similar to that of Trinidad Lake Asphalt (TLA ...

Coal Liquefaction | The Canadian Encyclopedia

Coal liquefaction processes were first developed in the early part of the 20th century but later application was hindered by the relatively low price and wide availability of crude oil and natural gas. Large scale applications have existed in only a few countries, eg, Germany during WWII and South Africa since the 1960s. The oil crises of the 1970s and the threat of depletion of conventional ...

Coal liquefaction - Wikipedia

Coal liquefaction is a process of converting coal into liquid hydrocarbons: liquid fuels and petrochemicals. This process is often known as "Coal to X", where X can be many different hydrocarbon-based products. However, the most common process chain is "Coal to Liquid Fuels" (CTL).

Coal Liquefaction - Dadyburjor - - Major .

Coal liquefaction incorporates both an increase in the H/C ratio and removal of heteroatoms (S, N, O) and inorganic oxides (ash). Successful industrial direct liquefaction processes must incorporate both these steps, along with the transport of solid and slurry ‐ phase material in large – scale processing. The H/C ratio can be increased using high temperatures and pressures and a solvent ...

Two other direct coal liquefaction processes were under development in the USA at the same time: the Exxon Donor Solvent (EDS) process and the H-Coal process. The distinguishing feature of the EDS process was a separate solvent hydrogenation step to carefully control the hydrogen donor characteristics of the solvent, and the most important feature of the H-Coal process was its use of an ...

Coal liquefaction | Britannica

Coal liquefaction, any process of turning coal into liquid products resembling crude oil. The two procedures that have been most extensively evaluated are carbonization—heating coal in the absence of air—and hydrogenation—causing coal to react with hydrogen at high pressures, usually in the presence of a catalyst.

Hydrothermal liquefaction - Factorio Mods

Similar to coal liquefaction it allows to turn raw-wood into crude-oil. Small amounts of crude-oil but still. But mod xyz already does that. Well, I did not find a (still maintained) mod that does just that. I didn't want a big mod with fancy new production chains with a lot of different recipes, I just wanted to do something useful with my raw-wood. So I created this for my own use. Version ...
