The coal hydrogenation gasification technology for co-producing methane and aromatics enables the efficient and clean conversion of coal into natural gas, while also generating high-value aromatic compounds as by-products. A pilot plant with a coal feeding capacity of 4 tons per day has been built, and an industrial demonstration plant with a capacity of 400 tons per day is about to be constructed. Under conditions of 800–1000°C and 5–10 Mpa, this technology enables the reaction of coal powder with hydrogen to produce methane, aromatic hydrocarbons, and semi-coke. Tests show that when the methane content is greater than 80%, the yield of aromatic oil products ranges from 10 to 15%. Coal hydrogenation gasification technology for co-producing aromatic compounds: components include benzene, naphthalene, pyrene; other components; content: 40-60%, 10-30%, 5-10%
This should fall under the category of coal-to-oil conversion – a process in which hydrocracking is carried out under high temperature and pressure to produce lighter products. It’s currently just a concept; to implement such industrial processes at these temperatures and pressures, it’s necessary to combine them with gasification, and the difficulty of industrializing this approach is very high
Strictly speaking, this does not count as coal-to-oil; the industrialization challenge is not significant, as the gasification temperature and pressure are much lower than those required for direct coal liquefaction. The key lies in the rationality of the process route
