Dealing more effectively with the bottom of the barrel is high on the refining industry’s agenda for a several reasons. Crude oil feedstocks are becoming heavier, which is making lighter crudes more expensive. Environmental pressures are undermining the market for heavy fuel oil. In addition, the demand for clean transportation fuels is growing.

There are several processes available to refiners seeking an upgrading solution. One of them is fixed-bed residue hydroconversion.

It has many advantages over thermal technologies such as delayed coking, but getting the most out of the process is not easy. Effective use of catalysts is the key to success.

Customised solutions

Choosing the best catalysts to function under the specific conditions prevailing in a fixed-bed residue upgrader requires considerable understanding.

At Criterion, we take what we call the 4Cs approach. It is important to be clear about the chemistry of what you are trying to achieve: removal of metals, sulphur, Conradson carbon residue (CCR) and asphaltenes. The composition of the feed is key. 

In addition, the conditions in the unit, the operating constraints and the way the process is configured will clearly have a bearing on the way forward. By getting to grips with these numerous variables on an individual unit basis, we can customise catalyst systems that meet each refiner’s needs.
