Fluidized bed reactor applied to adsorption desulfurization and application thereof

Abstract

The invention discloses a fluidized bed reactor applied to adsorption desulfurization and application thereof. The fluidized bed reactor comprises a reaction section (7), a pipe diameter enlarged settling section (5) and a separation section (3) from bottom to top, wherein an adsorbent inlet, an oil-gas inlet, a gas inlet and an outlet for an adsorbent to be generated are formed in the reaction section (7); the top of the separation section (3) is provided with a filter (2); an oil-gas outlet is formed in the top of the filter; the inside of the settling section (5) and the inside of the separation section (3) are provided with a dust collecting hopper (4). The upper part of the fluidized bed reactor is provided with the dust collecting hopper, so that the absorbent dust generated in the reaction process can be effectively collected and transported out of the fluidized bed reactor; the dust concentration on the top of the reactor can be controlled manually, so that a gas-solid separation device on the top of the reactor operates with high stability, and the long-term, safe and stable operation of the reaction device is realized.

Description

technical field [0001] The invention relates to a fluidized bed reactor used for adsorption desulfurization and its application, belonging to the field of petrochemical industry, in particular to a fluidized bed reactor used in the method of adsorption desulfurization and removal of sulfide in hydrocarbon oil . Background technique [0002] As people pay more and more attention to environmental protection, the restrictions on sulfur content in light hydrocarbons are becoming more and more stringent. Taking gasoline as an example, the European Union has stipulated that the sulfur content should not exceed 50 μg / g in 2005, and the Euro V gasoline standard planned to be implemented in 2010 stipulates that the sulfur content should be less than 10 μg / g. China's National III standard, which was implemented on December 31, 2009, stipulates that the sulfur content of gasoline should not exceed 150 μg / g. Therefore, if China's fuel oil standards are to be in line with international ...

Problems solved by technology

Although the use of the dust suppressor can effectively reduce the backflush time of the filter, most of the catalyst dust still remains in the reactor, and the impact on the filter still exists
