Hydrogenation of coal - NEUMAN & ESSER
Hydrogenation of coal is a high-pressure process at a pressure of up to 700 bar and 550°C. For the hydrogenation process in the reactor under the operating conditions mentioned, hydrogen is required as a fresh gas and as a cycle gas. The fresh hydrogen is obtained from a gas storage facility and the circulating gas is recycled within the process.
