Claim:
1. A method of operating a SHC reactor comprising: delivering heavy hydrocarbon feed, hydrogen and catalyst to a SHC reactor; cracking the feed over catalyst in the presence of hydrogen at predetermined reaction conditions; taking a sample of material from the SHC reactor; blending the sample with a solvent; decanting a liquid phase from the sample; drying the liquid phase to provide a remaining solids; mixing the remaining solids with a second solvent to provide a mixture; evaporating the second solvent from the mixture to provide a TIOR solids, determining the presence of mesophase insoluble in toluene in the sample by identifying the presence of a peak at 26 two theta degrees plus or minus 0.3 two theta degrees in an XRD plot, wherein the XRD plot is based upon the TIOR solids; and adjusting the reaction conditions in response at least in part to the determination of the presence of mesophase in the sample.
