A key feature of the Hcoal process is the use of an ebullated bed for achieving good mixing between slurried coal, hydrogen, and extruded catalyst particles. The Hcoal reactor can be modeled as a fourphase fluid bed system containing liquid, fines, gases, and catalyst particles. In order to study the hydrodynamic behavior of this gas/slurry ...

The HCOAL process was developed by HRI Company from the fluidizedbed heavy oil hydrocracking process (HOil). The process utilizes a fluidized bed catalytic reactor which has the reaction temperature range of 425 to 455°C, having the pressure of 20 MPa where the catalyst is aluminate extruded bar with alumina as the carrier. The inner part ...
Results of an investigation to determine the suitability of the HRI HCoal Syncrude as a petrochemical feedstock are reported. A sample of the whole crude was distilled into four straight run fractions; IBP350/sup 0/F naphtha, 350550/sup 0/F middistillate, 450800/sup 0/F vacuum gas oil, and 850FBP/sup 0/F resid.

In pyrolysis processes, the H/C ratio of coal is raised by rejecting carbon. The liquid products have little value, but pyrolysis is used on a massive scale to turn coal into coke for metallurgy, especially steelmaking. The coking process involves heating coal in closed vessels to very high temperatures (up to 2,000°C) in the absence of oxygen.
