Problems solved by technology

Its advantage is that it does not need fractional distillation to process full-fraction FCC gasoline. The disadvantage is that most of the residual sulfides in the final product are mercaptan sulfur compounds, which leads to unqualified mercaptan sulfur in the product
Its disadvantage is that it cannot meet the technical requirements of refineries

Example Embodiment

[0031] Example 1:

[0032] Weigh 100g pseudo-boehmite, add 2.5g sesame powder, and then add 3% nitric acid aqueous solution, knead and extrude, dry at 120°C for 4h, and then calcinate at 650°C for 4h to prepare a catalyst carrier. Test the water absorption of the carrier according to the conventional method, and then configure the active component dipping solution according to the water absorption of the carrier according to the equal volume dipping method. First, weigh out 45ml of ammonia, then add 2g of ammonium molybdate, 3g of cobalt nitrate, and 51g of nickel nitrate in sequence and stir to dissolve, and finally make the volume constant with ammonia. The carrier was impregnated with an equal volume impregnation method to make the catalyst carrier fully absorb the active component impregnation solution, and then placed for 12 hours, the catalyst was dried at 120°C for 4 hours, and calcined at 500°C for 4 hours to prepare a catalyst sample Cat-1#.

Example Embodiment

[0033] Example 2:

[0034] According to the carrier preparation method in Example 1, 100 g of the catalyst carrier was prepared, and then the active component impregnation solution was configured. The preparation method was the same as in Example 1. First, weigh 50ml of ammonia, then add 4g of ammonium molybdate, 10g of cobalt nitrate, and 62g of nickel acetate in sequence and stir to dissolve, and finally make the volume constant with ammonia. The metal active component impregnation method, drying and calcination conditions were the same as in Example 1, and the catalyst sample Cat-2# was prepared.

Example Embodiment

[0035] Example 3:

[0036] According to the carrier preparation method in Example 1, 100 g of the catalyst carrier was prepared, and then the active component impregnation solution was prepared, and the catalyst was prepared by impregnation in two steps. First, weigh 40ml of ammonia, then add 4g of ammonium molybdate, 6g of cobalt nitrate, and 34g of nickel acetate and stir until it dissolves, and finally make the volume constant with ammonia. The metal active component impregnation method, drying and roasting conditions were the same as in Example 1. A primary impregnated catalyst sample was prepared; the above catalyst sample was impregnated twice, 40ml ammonia water was weighed, and then 4g ammonium molybdate, 6g cobalt nitrate and 21g acetic acid were added. The nickel is stirred until it dissolves, and finally the volume is made constant with ammonia water. The metal active component impregnation method, drying and calcination conditions were the same as in Example 1, and t...

Abstract

The invention relates to a method for catalyzing gasoline deep desulfurization with an Ni-Mo-Co containing catalyst. Specifically, a gasoline raw material enters a first reactor to undergo selective hydrodesulfurization and then enters a second reactor to further undergo deep desulfurization. The hydrodesulfurization catalyst adopted by the second reactor is the Ni-Mo-Co containing catalyst. The catalyst has certain desulfurization activity, and at the same time has little olefin saturation, after combination with the first reactor, further deep desulfurization can be realized, and simultaneously the reaction severity of the first reactor can be significantly reduced, so that the octane number loss and hydrogen consumption can be optimized.

Description

technical field [0001] The invention relates to a method for deep desulfurization of gasoline, in particular to a method for adding a second hydrodesulfurization reactor after the first hydrodesulfurization reactor for gasoline deep desulfurization. Background technique [0002] Petroleum is one of the most important energy sources and has become the "blood" of today's world economic development. With the rapid development of the global economy, car ownership is increasing day by day. As of September 2011, the number of cars in the world has exceeded 1 billion, and the number of cars in my country has also exceeded 100 million for the first time. Automobile exhaust has become the main source of air pollution in many cities, seriously affecting people's production, life and health. At present, environmental protection laws and regulations are becoming increasingly stringent, countries all over the world have put forward higher and higher requirements for the quality of vehic...
