1. Modeling of Processes and Reactors for Upgrading of Heavy Petroleum

   By Jorge Ancheyta

   Series: Chemical Industries

   The worldwide petroleum industry is facing a dilemma: the production level of heavy petroleum is higher than that of light petroleum. Heavy crude oils possess high amounts of impurities (sulfur, nitrogen, metals, and asphaltenes), as well as a high yield of residue with consequent low production of...

2. Asphaltenes

   Chemical Transformation during Hydroprocessing of Heavy Oils

   By Jorge Ancheyta, Fernando Trejo, Mohan Singh Rana

   Series: Chemical Industries

   During the upgrading of heavy petroleum, asphaltene is the most problematic impurity since it is the main cause of catalyst deactivation and sediments formation. Exploring many aspects related to asphaltenes composition and conversion, Asphaltenes: Chemical Transformation during Hydroprocessing of...

3. Hydroprocessing of Heavy Oils and Residua

   Edited by Jorge Ancheyta, James G. Speight

   Series: Chemical Industries

   Many oil refineries employ hydroprocessing for removing sulfur and other impurities from petroleum feedstocks. Capable of handling heavier feedstocks than other refining techniques, hydroprocessing enables refineries to produce higher quality products from unconventional — and formerly wasted —...
