Hydrocracking Process by Haldor

Application: Topsøe’s hydrocracking process can be used to convert straight run vacuum gas oils and heavy cracked gasoils to high quality “sulfur-free” naphtha, kerosene, diesel, and FCC feed, meeting current and future regulatory requirements. In addition, high VI lube stocks and petrochemical feedstock can be produced to increase the refinery’s profitability.

Product: By proper selection of operating conditions, process configuration, and catalysts, the Topsøe hydrocracking process can be designed for high conversion to produce high smoke point kerosine and high cetane diesel. The process can also be designed for lower conversion/upgrade mode to produce low sulfur FCC feed with the optimum hydrogen uptake or high VI (>145) lube stock. The FCC gasoline produced from a Topsøe hydrocracking unit does not require post-treatment for sulfur removal.

Description: Topsøe’s hydrocracking process uses well proven co-current downflow fixed bed reactors with state – of – the – art reactor internals and catalysts. The process uses recycle hydrogen and can be configured in partial conversion once-through feed mode or with recycle of partially converted oil to obtain 100% conversion to diesel and lighter products. Topsøe’s zeolitic and amorphous hydrocracking catalysts have been proven in several commercial hydrocrackers.

Operating conditions: Typical operating pressure and temperatures range from 55 to 170 bar (800 to 2500 psig) and 340 to 420°C (645 to 780°F).
