摘要： The present invention is directed to a method for the prediction of coke morphology from feed characteristics using cross-polarized light optical microscopy, image segmentation, and statistical analysis. In particular, the method comprises performing a microcarbon test (MCRT) on a coker feed, ASTM D 4530 to produce a MCRT coke sample, using cross-polarized light optical microscopy at 100X, 200X or 500X, preferably 500X, to produce a photo of the MCRT coke sample, using machine learning segmentation software to produce a segmented output file that comprises a partitioned image with multiple segments, determining structural parameters of output file by applying statistical analysis weighted by area, and correlating the resulting statistical analysis to a coke morphology. Preferably, the structural parameter is Feret maximum, number of particles less than or equal to 100 microns or area calculated by statistical analysis.

摘要： Disclosed is a process for in situ upgrading of a heavy hydrocarbon comprising the steps of: (a) positioning a well in a reservoir containing a heavy hydrocarbon having an initial API gravity of less than or equal to about 20, an n-heptane asphaltene content as measured by the ASTM D-6560 of at least about 1 wt.%, and a viscosity at 35°C greater than about 350 centistokes (cSt); (b) injecting one or more hydrocarbon solvents and one or more asphaltene precipitant additives into the well in any order at a ratio by volume of the solvent to the heavy hydrocarbon of at least from about 0.1:1 to about 20:1 under reservoir conditions so as to provide an upgraded hydrocarbon in the reservoir, wherein the upgraded hydrocarbon has an improved API gravity greater than the initial API gravity, a reduction in the asphaltene content, and a lower viscosity; and (c) producing the upgraded hydrocarbon from the well. The process of the present invention can be also carried out at higher temperatures such as by injecting steam with the one or more hydrocarbon solvents and the one or more asphaltene precipitant additives into the well in any order.
