Then, coalification and the classification of coal are described. The main part of the article is devoted to the most important processes using coal where challenges for catalysis still exist, with a focus on recent literature. First, technologies based on the production of synthesis gas, i.e., Fischer-Tropsch synthesis as well as MTO/MTP (Methanol To Olefins/Methanol To Propylene), are discussed. Secondly, direct coal liquefaction is treated. The last part of the article is devoted to "clean" coal and gives an outlook on the future of coal.

This CB[7]-[C(n)mim]Br complex can be removed from the mixture and a subsequent solid state ion metathesis affords pure CB[7]. Moreover, the imidazolium ionic liquids can be recycled from the aqueous solution after the purification thus providing a 'green' process.

Acceptance of the feasibility and general applicability of the reaction depends upon the ability of researchers to bring it into the mainstream by development of: (1) an understanding of the mechanism of the reaction; and (2) the design of catalysts which promote the reaction on a wide range of substrates and under ambient conditions. From the earliest report of the direct amide formation in the 19th century, there have been relatively few reports of mechanistic studies, though it is clear that there is not a simple relationship between ease of direct amide formation...
