摘要： Processes for producing olefins include integration of steam cracking with a dual catalyst metathesis process. The processes include steam cracking a hydrocarbon feed to form a cracking reaction effluent containing butenes, separating the cracking reaction effluent to produce a cracking C4 effluent including normal butenes, isobutene, and 1,3-butadiene, subjecting the cracking C4 effluent to selective hydrogenation to convert 1,3-butadiene in the cracking C4 effluent to normal butenes, removing isobutene from a hydrogenation effluent to produce a metathesis feed containing normal butenes, and contacting the metathesis feed with a metathesis catalyst and a cracking catalyst directly downstream of the metathesis catalyst to produce a metathesis reaction effluent. Contacting with the metathesis catalyst causes metathesis of normal butenes to produce ethylene, propene, and C5+ olefins, and contacting with the cracking catalyst causes C5+ olefins produced through metathesis to undergo cracking reactions to produce additional propene, ethylene, or both.

摘要： Provided is a novel catalyst for use in the second stage of a two-stage hydrocracking process. The present process comprises hydrocracking a hydrocarbon feed in a first stage. The catalyst in the first stage is a conventional hydrocracking catalyst. The product from the first stage can then be transferred to a second hydrocracking stage. The catalyst used in the second stage of the present hydrocracking process comprises a base impregnated with metals from Group 6 and Groups 8 through 10 of the Periodic Table, and an organic acid. The base of the catalyst used in the present second hydrocracking stage comprises alumina, an amorphous silica-alumina (ASA) material, and a USY zeolite. Improved naphtha production is achieved.

Particularly, a process for producing BTX from a feedstream comprising C5-C12 hydrocarbons is provided comprising the steps of: (a) contacting said feedstream in the presence of hydrogen with a combined hydrocracking/hydrodesulphurization catalyst to produce a hydrocracking product stream comprising BTX; and (b) separating the BTX from the hydrocracking product stream. The hydrocracking/hydrodesulphurization catalyst comprises 0.1-1 wt-% hydrogenation metal in relation to the total catalyst weight. The hydrocracking/hydrodesulphurization catalyst further comprises a zeolite having a pore size of 5-8 Å and a silica (SiO2) to alumina (Al2O3) molar ratio of 5-200. The hydrocracking/hydrodesulphurization conditions include a temperature of 450-580° C., a pressure of 300-5000 kPa gauge and a Weight Hourly Space Velocity of 0.1-10 h−1.

摘要： Embodiments herein relate to a process flow scheme for the processing of gas oils and especially reactive gas oils produced by thermal cracking of residua using a split flow concept. The split flow concepts disclosed allow optimization of the hydrocracking reactor seventies and thereby take advantage of the different reactivities of thermally cracked gas oils versus those of virgin gas oils. This results in a lower cost facility for producing base oils as well as diesel, kerosene and gasoline fuels while achieving high conversions and high catalyst lives.
