Coal Production - an overview | ScienceDirect Topics
World coal production increased by 3.1% in 2017 after falling for 3 years The trend changed in 2017 with a total production of 7549 Mt as per IEA Key Statistics 2018. Coal is made up of thermal coal, coking coal, and lignite, and the data for the last 3 years are tabulated in Table 2.2. About 75% of the total coal produced is steam coal. Table 2.2.

Catalytic Conversion of Coal and Biomass Volatiles: A Review
The first step is the pyrolysis of solid fuel (e.g., coal and biomass) to produce non-condensable gas (H 2, CO 2, CO, and low carbon hydrocarbons), condensable volatiles (liquid oil), and solid char. This step is relatively fast and also frequently termed as devolatilization. The second step is the reforming of volatiles in the gas phase. Table 1.
