ResumoTitiribi coal from Colombia shows an excellent reactivity to liquefaction and coprocessing. Anthracene oil was excellent as a vehicle oil to facilitate the liquefaction reaction during the initial stage at 400°C. In the case of coprocessing with Morichal crude oil and red-mud/sulfur catalyst, the maximum conversion of Titiribi coal was ca. 79 wt% daf at 400°C and ca. 93 wt% daf at 450°C. The hydrogen consumption in the presence of Morichal crude oil is lower than that in the presence of anthracene oil. It is considered to be the effect of hydrogen sulfide and the hydrogen donor ability of Morichal crude oil.
