UOP to Offer Albemarle NEBULA Catalyst for Ultra-Low-Sulfur Diesel Through Hydroprocessing Alliance

UOP LLC, a Honeywell company, will offer the Albemarle NEBULA hydrotreating catalyst for the production of high-quality, ultra-low-sulfur diesel (ULSD) as part of the Hydroprocessing Alliance, UOP’s strategic alliance with Albemarle Corp.

NEBULA catalyst is an innovative material jointly discovered by ExxonMobil Research and Engineering Company and co-developed with Albemarle that offers greater catalyst activity and can enhance diesel yield and quality. The Hydroprocessing Alliance will now offer the catalyst for reloads and revamps of hydroprocessing units.

The NEBULA catalyst can be used as a drop-in for hydrocracker reloads to allow them to produce more ULSD without costly modifications to the unit. This is a distinct advantage as the demand for diesel continues to grow and environmental specifications get stricter.

—UOP Alliance Director Jim Kennedy

The NEBULA catalyst is a base-metal catalyst with higher activity than conventional hydrotreating catalysts. In addition to supporting production of ULSD without additional capital investment, NEBULA can enhance hydrotreating unit revamps to reach higher throughputs or achieve higher product quality standards.

Additionally, NEBULA’s high hydrodenitrogenation (HDN) and hydrodearomatization (HDA) activities can debottleneck hydrocrackers that have limited hydrotreating activity. It has been used in more than 40 applications since its introduction in 2001.

UOP and Albemarle formed the Hydroprocessing Alliance in 2006. The alliance combines the strengths of UOP, a leading developer of hydrotreating and hydrocracking process technology and hydrocracking catalysts, and Albemarle, a leading developer and supplier of innovative refinery hydrotreating catalysts and technologies, to provide the refining industry with a broad portfolio of process and catalyst offerings for middle distillate hydrotreating, vacuum gas oil hydrotreating, mild hydrocracking, hydrocracking, and fixed-bed residue hydrotreating.

It is amusing that many tons of sulphur are put on soils every year by farmers, and that inspite of reports of acid rain there are articles about the deficiencies of sulphur in farm soil. The human body requires sulphur in most if not every cell, plants do as well. A methane making factory in North Dakota captures and sells most of the sulphur byproduct that it produces. There may be places of intensive agriculture where sulphur spewing smokestacks are a benefit to local agriculture, but too much in a concentrated area is obviously deadly as demonstrated by the absence of vegetation in photographs of old metal refinining areas. ..HG..
