Journal Alert: PTQ (Petroleum Technology Quarterly)

"The storm had now definitely abated, and what thunder there was now grumbled over more distant hills, like a man saying "And another thing…" twenty minutes after admitting he's lost the argument." From: So Long, and Thanks for all the Fish, By Douglas Adams

The articles in PTQ-Petroleum Technology Quarterly (www.eptq.com) occupy a middle ground between cutting edge research and hands-on how-to.  The articles are clearly written, well illustrated, and long enough to provide enough detail to give a clear picture of the practical application of the latest proven technologies.

Key words I culled from a recent PTQ article … described below … include:

·         UFQ - Ultra Flat Quench

·         single-state enhanced aromatics saturation

·         SRO - selective ring opening

Here are excerpts from that article …

"The technical challenge, however, will be to maximize this volume while simultaneously meeting the increased fuel quality requirements, particularly the specifications for sulphur, boiling point, density, cetane and cold flow properties.  The good news, and the subject of this article, is that ULSD can act as an enabler for further upgrading."

"ULSD Chemistry: Good Match with Diesel Upgrading

“There are two key elements of ULSD that make diesel upgrading easier when compared with the older low-sulphur diesel (LSD) operation: a richer hydrogenation environment and a cleaner product that is devoid of most sulphur and nitorgen species.  Both of these factors promote aromatic saturation, ring opening, isomerization and cracking reactons.

"This improved operating environment can then be leveraged in a number of different ways to capture a range of upgrading opportunities.  There are two key enablers for implementing these upgrading opportunities: high-activity ULSD catalysts and reactor process technology, both of which are required to implement the additional chemistries."
