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 to produce clean gasoline with a sulfur content of ≯10μg / g
[0008] To sum up, from the retrieval of patent documents, the currently researched and applied gasoline hydrodesulfurization technology is mainly used to produce products with a sulfur content of ≯150μg / g, but no products with a sulfur content of ≯10μg / g have been seen. technology reports

Embodiment 1

[0032] Weigh 100 g of pseudo-boehmite, add 2.5 g of sesame powder, and then add 3% nitric acid aqueous solution, knead and extrude, dry at 120°C for 4 hours, and then calcinate at 650°C for 4 hours to prepare a catalyst carrier. Test the water absorption of the carrier according to the conventional method, and then configure the active component impregnation 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 cobalt nitrate and 60g of nickel nitrate in sequence until it dissolves, 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#.

Embodiment 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 out 50ml of ammonia, then add 5g of cobalt nitrate and 42g of nickel acetate 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.

Embodiment 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 configured. The preparation method was the same as in Example 1. First weigh 50ml of ammonia, then add 8g of cobalt nitrate and 30g of nickel acetate 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-3# was prepared.

Abstract

The invention relates to a method for catalyzing gasoline deep desulfurization with an Ni-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 second reactor adopts a highly selective hydrodesulfurization catalyst, which is an Ni-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 the deep desulfurization of gasoline. Background technique [0002] Petroleum is one of the most important energy sources and has become the "blood" of economic development in the world today. With the rapid development of the global economy, the number of cars is increasing day by day. As of September 2011, the global car ownership has exceeded 1 billion, and my country's car ownership has exceeded 100 million for the first time. Car exhaust has become the main source of air pollution in many cities, which has a serious impact on people's production, life and health. At present, environmental protection laws and regulations are becoming more and more stringent. Countries all over the world have put forward higher and higher requirements on the quality of vehicle ...
