New Haldor Topsoe catalyst boosts profitability of diesel and hydrocracking units

Published by

Refiners can experience longer cycle lengths, high value products from low quality feed stocks, and increased volume swell with the latest HyBRIMTM nickel molybdenum catalyst with 25% improved activity for both nitrogen and sulfur removal.

The high activity of Haldor Topsoe’s new TK-611 HyBRIM catalyst offers new possibilities to either increase profitability of high pressure ultra low sulfur diesel production from heavy feed stocks or to guarantee a superior pretreatment for the hydrocracking unit. Refiners can process more severe feeds, increase cycle lengths by several months, achieve larger volume swells, or maximise unit throughput. HyBRIM also supports profitability by substantially improving the cetane number of the final product.

The improved activity for nitrogen removal improves overall hydrocracking unit performance because it lowers the nitrogen slip from the pre-treatment step to the second stage in the hydrocracker. This minimises inhibition of the hydrocracking catalyst enabling higher conversion and selectivity.

The HyBRIM™ technology combines the well-proven BRIM® technology with an improved catalyst preparation step. This leads to optimal interaction between the active metal structures and the catalyst carrier, which increases activity while delivering the same high stability.

TK-611 is the successor to TK-609 of the HyBRIM series. More than 200 charges of HyBRIM catalyst have been sold to date. All HyBRIM catalysts are produced at Topsoe’s own ISO-certified and REACH-compliant manufacturing sites under rigorous quality control.
