Abstract:
1. A process for conversion of coal to aromatic compounds, comprising: a) liquifying coal in the presence of hydrogen, b) separating effluent obtained at the end of a) into a light fraction of hydrocarbons containing compounds boiling at most at 500° C. and a residual fraction, c) hydrocracking at least a proportion of said light fraction of hydrocarbons obtained at the end of step b) in the presence of hydrogen in at least one reactor containing a fixed-bed hydrocracking catalyst, with a conversion of 200° C.+ fraction being greater than 30 wt %, d) separating effluent obtained at the end of step c) into at least a naphtha fraction containing between 1-50% wt % paraffins, 20-99 wt % naphthenes, a nitrogen content below 0.5 ppm and a sulphur content below 0.5 and a fraction heavier than the naphtha fraction, e) catalytic reforming the fraction containing naphtha, without pretreatment, giving hydrogen and a reformate containing aromatic compounds, f) separation of aromatic compounds from the reformate.
