Webbcover slurry-phase hydrocracking technology for upgrading vacuum residue and the production economics thereof. The main advantage of the slurry-based process is that it can process a variety of feedstocks from refinery residue with more than 90% conversion. Also, as dispersed catalyst is used in the reactor, it is not prone to pluggi ng from coke.
