More specifically, the method of producing a liquid hydrocarbon product includes heat soaking a tar stream to produce a reduced reactivity tar, and blending the reduced reactivity tar with a working fluid including a recycled solvent to produce a lower viscosity, reduced reactivity tar. The process also includes hydrotreating the lower viscosity, reduced reactivity tar at a temperature greater than 350 ℃ to produce a total liquid product containing liquid hydrocarbon product and recycled solvent. The method further includes separating the recycle solvent from the total liquid product and flowing the recycle solvent to the reduced reactivity tar for blending to produce a lower viscosity, reduced reactivity tar, wherein the recycle solvent has S BN Is greater than 110.)
