The reacivites of preasphaltenes obtained by liquefaction of Illinois No.6 coal, PA (I), and Morwell brown coal, PA (M), were studied for hydrotreating in the presence or absence of a catalyst under hydrogen pressure of 8 MPa (coal charge) and temperature range from 320 to 440°C. The feed preasphaltenes were easily converted to THE insoluble fraction during preservation at room temperature; 35 wt% of THFI from PA (I) and 60wt% THFI from PA (M). In the reaction of PA (I) without catalyst, craking of THEI to PA, cracking of PA to asphaltene and polymerization of PA to THFI were the major reactions and the production of hexane soluble fraction (HS) was scarcely observed. Especially, polymerization of PA to THEI was very remarkable at 440°C. The presence of catalyst promoted reactions to produce asphaltene and HS and prevented the formation of THFI. In the reaction of PA (M), rather large amout of HS was produced when catalyst was not used. The productions of asphaltene and HS increased by the existence of catalyst, whereas, similar yields of THEI were obtained in both cases of presence and absence of catalyst at 440°C, which suggests that catalyst may be deactivated easfly by the PA (M) reaction at 440°C.
