About Us


Hydrocracking (HC) is utilized in refineries to upgrade a variety of feeds that range from coker naphtha to various heavy gas oils and residual fractions into lighter molecules. The HC process is a predominant diesel (or called gasoil) producer in many refinery configurations. As environmental regulations on transportation fuels continue to tighten, the hydrocracker will be one of the few tools available to refiners to yield ultra-low sulfur diesel (ULSD). Furthermore, high-pressure hydrocracking can achieve near 100% conversion of many different feeds to high-viscosity index (VI) lube oil base stocks.

Depending on market conditions, hydrocracking units can also offer improved flexibility to shift production modes between gasoline and diesel based on process selection, operating conditions, and catalysts used. Lately, hydrocracking fats and oils and biomass to produce renewable diesel and sustainable aviation fuel has been an important strategy to reduce refinery carbon footprint.

How it will benefit you

The study aims at providing hydrocracker operators with the latest process innovations, reactor internal designs, and catalyst technologies and experiences in maintaining the profitability of the unit in processing heavier feedstreams, including heavy vacuum gas oil (HVGO), FCC LCO, coker gas oil, visbroken gas oil, deasphalted oil, and resid feeds, while minimizing the hydrogen consumption and boosting overall energy efficiency.

What does it include

The current study, completed in 2Q2020, begins by looking at the global hydrocracking market including middle distillate supply and demand fundamentals and prices and what impact COVID-19 will have on distillates demand in the short term.

In addition to a comprehensive list of state-of-the-art technologies, recent innovations feature the new offerings by Chevron Lummus Global, CLG (Optimized Partial Conversion (OPC) process, where heavier residue-derived VGO is processed alongside high endpoint straight-run VGO with a bleed to the FCCU), Haldor Topsoe (TK-564 HyBRIM catalyst for use in mild hydrocrackers), Honeywell UOP (HC-120 hydrocracking catalyst from Unity hydroprocessing catalyst line designed to optimize cold flow properties), Shell (Molecular Access Catalysts for Hydrocracking (MACH); and Z-NP10 and Z-NP20 maximum activity, naphtha-selective cracking catalysts), and more.

To address increasing trends of crude-to-chemicals, the use of resid hydrocracking technologies from Axens, CLG, and Honeywell UOP is discussed in details.

In computer simulation and modeling developments, the study focuses on the development of a commercial simulation model for a single-stage, once-through hydrocracking unit at the Tupras Izmit refinery in Turkey.

The study also includes extensive discussions of plant operations and practices that identify valuable operating experiences and daily trouble-shooting techniques shared by veteran refining professionals around the world. A recent key knowledge shows how to properly address high levels of water content in hydrocracker feed, and a proper catalyst selection when hydrocracking LCO.

Looking ahead , the study discusses the latest patent applications and research papers regarding hydrocracking technology including novel hydrocracking catalyst compositions and preparation methods; product-selective hydrocracking innovations designed to maximize the output of middle distillates, high-octane gasoline, heavy naphtha, or BTX; resid hydrocracking works including ebullated- and slurry-bed developments; hydrocracking of alternative feeds derived from Fischer-Tropsch (F-T) liquids and bio-based feeds and more.

Finally, global installed capacity and recent construction activities are summarized in the study to track the growth of HCUs around the world.
