Honeywell UOP has introduced a new catalyst that can more efficiently remove sulfur and nitrogen from lower-value diesel blending components, allowing them to meet Euro V clean fuels specifications.
Honeywell UOP’s ULTIMet™ catalyst has more active sites for chemical reactions and can be used as a drop-in reload to “debottleneck” a unit, resulting in increased plant capacity with no additional capital expense. The new catalyst also can be loaded in combination with conventional hydrotreating catalysts to further improve their performance.
“The ULTIMet catalyst enables refiners facing stricter fuel requirements to achieve higher quality product specifications and greater profitability,” said Jose Carrazza, Vice President and General Manager of Honeywell UOP’s Catalysts, Adsorbents & Specialties business.
The ULTIMet catalyst also has the high strength and attrition resistance necessary to prevent breaking, which ensures a more reliable operation and helps extend the operating cycle by as much as 50 to 75%.
Hydrotreating is a critical step in the refining process where hydrogen and a proprietary catalyst are used to remove sulfur and other contaminants before conversion into transportation fuels. The process produces a cleaner-burning diesel fuel product that meets new fuel regulations such as the Euro V standard, which specifies sulfur content of less than 10 parts per million in transportation fuels.
Honeywell UOP inaugurated the use of catalysts in the refining industry in 1931, beginning with solid phosphoric acid. This and subsequent processes significantly raised the yield of high-octane transportation fuels.
In January, the company announced that UkrGasVydobuvannya (UGV) has begun using Honeywell UOP’s HYT-4118 Unity hydrotreating catalyst to produce ultra-low sulfur diesel fuel at the Shebelinsky refinery in Andreyevka, Kharkov Region, in eastern Ukraine.
The HYT-4118 catalyst removes sulfur from petroleum feeds that are used to make distillate, the raw material for making cleaner-burning diesel fuel. The catalyst is designed for use in low- to medium-pressure ultra-low sulfur diesel hydrotreating units, providing high activity and stability for longer cycle lengths with low hydrogen consumption. It works with a range of feedstocks including straight run diesel, light cycle oils, light coker gas oils and other cracked feedstocks.
