When coal liquefaction is conducted in a liquid phase, i.e., in the presence of a solvent, dissolution is usually considered an essential first step. While kinetic evaluation for individual reactions is possible for chemical models, the same is not true for coal. Generally

These processes can all be enhanced by the use of catalysts (for example, catalytic pyrolysis or catalytic hydropyrolysis, Exxon Donor Solvent Process and catalytic two-stage liquefaction). Catalysis is necessary because there are
