Abstract: The relative contents of coal macerals vary w ith geological time.Therefore, i t muse m ake errors to calcu- late the amounts of hydrocarbons generated during geohistory based on the present tes test maceral com posi- tions.The present paper gives out a method fo r recovering the relative content of coal m acerals in the geohisto- ry.The further research shows that the relative content variation of the liptini te is the largest during the geo- historical process, then are the virtrinite and fusini te.And the amounts of CH4, C 2-C 4 and liquid oil generated in coal during geohistory will be underestim ated if the calculation is based on the present maceral compositions Thei r maximum theoretical deviations can reach to as hig has 32.72 %, 3 2.25 % and 14.04 %, respectively.
