Abstract: This article has summarized the optimized measures relating to the loading of catalyst, and the sixth operating cycle of the residue hydrotreating unit at SINOPEC’s Maoming Branch Company, and made a detailed comparison on the impurities removal rate, hydrogen consumption and energy consumption of the sixth operating cycle with those achieved by the previous five cycles. Test results have revealed that the second-generation RHT series novel residue hydrotreating catalysts featured high activity, good stability, and long operating cycle and could remarkably reduce the hydrogen consumption and energy consumption of process unit. The hydrotreated AR product, having low Conradson carbon residue, low sulfur content, low metal content, high content of saturated hydrocarbons, and low content of asphaltenes and resins, is an excellent FCC feed. Judging from their overall property the second-generation RHT series of residue hydrotreating catalysts used in the sixth operating cycle have commanded a leading position among other catalysts used in previous operating cycles.
