Experimental study and evaluation on hydrocarbon generation of macerals

Some typical coal and maceral samples are selected for oil and gas-generati ng systematic thermal simulation experiments, Rock-Eval, GC and GC-MS analy ses. Results cause productivity curves of extracts and gaseous, light, liqu id as well as total hydrocarbon. Effects of macerals and maturation on hydr ocarbon productivities and compositions are synthetically discussed. Evalua tion indexes and plan on coal-generated oil and gas in bituminous coal rank are suggested according to the data from experiments and analyses.
