Recent studies have shown that NiMo catalysts supported on carbon nanoparticles (Ketjen Black: KB) are very effective for the conversion of low-rank coals to oil; however, because of the high cost of Mo, lower cost alternative metals are desired.
This chapter presents the history of catalysis. The name "catalysis" was coined by Berzelius in 1836. He concluded that besides "Affinity" a new force is operative, the "Catalytic Force".
INTRODUCTION A Brief History of Coal Liquefaction Interest in coal liquefaction has had several high and low periods over the last 60 years. It starts just
Clean liquid fuels from direct coal liquefaction: chemistry, catalysis, technological status and challenges Sivakumar Vasireddy,a Bryan Morreale,b Anthony Cugini,b Chunshan Songc and James J. …
The direct liquefaction route, that is, coal hydrogenation, has a long history with origins in the early years of this century. It also has the distinction of being a process which was once operated on a very large scale and which, having died, now shows every prospect of resurrection. The technology which finally emerges will doubtless differ significantly from the original practice, but it ...
The Bergius process for the hydroliquefaction of coal has an 80-year history. This selective review attempts to trace the role of catalysis, and especially of catalyst dispersion, in this process.

Abstract. Among the many coal conversion processes are those that produce liquid fuels from solid coal. It is not easy to do this, and one underlying problem is apparent even from a casual inspection of the mass or elemental formulas of coal and some other common fuels.
This chapter is dedicated to the memory of Dr. Matthias Pier. The work covered herein was conducted to a great part in his department at Ludwigshafen under his inspiring guidance. Coal liquefaction is now recognized as a process of immense future significance for the production of alternative liquid
Coal Liquefaction Catalysis Catalysis plays an important role in coal liquefaction and has led to important technical advances and improved economics for producing liquid synfuels. A catalyst is defined as a substance which accelerates or changes the course of a chemical reaction without being consumed itself. The influence of the catalyst on liquefaction rate is actually not very noticeable ...

Coal liquefaction can be defined as the conversion of solid coal to products which are liquid at ambient temperatures. Usual methods for direct liquefaction processing are pyrolysis, solvent ...
Looking back on the history of industrial catalysis one is led to speculate on what lies ahead. It is clear that environmental catalysis will have a big impact, and catalysis will be needed to address increased sulfur and NOx emissions, lower CO 2 levels, and alternative fuels.

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).
