Example Embodiment

[0033] Example 1

[0034] Preparation of supported zinc hydroxide desulfurizer

[0035] 0.2441g ZnSO 4 ·H 2 Dissolve O in 5mL water, add 0.5g silica, ultrasonic for 30min, use 5wt% NH 3 ·H 2 O adjust the pH to 10, stir at room temperature for 24 hours, wash with water, and dry at 60°C for 6 hours to obtain a supported zinc hydroxide desulfurizer. The mass ratio of metal hydroxide to carrier in the desulfurizer is 10:100.

Abstract

The invention provides a supported hydroxide high-selectivity gasoline adsorption deep desulfurizing agent and a preparation method thereof. The supported hydroxide high-selectivity gasoline adsorption deep desulfurizing agent is prepared from a carrier and metal hydroxide supported on the carrier; the mass ratio of the metal hydroxide to the carrier is (5 to 30) to 100. The invention further provides the preparation method of the supported hydroxide high-selectivity gasoline adsorption deep desulfurizing agent. The supported hydroxide high-selectivity gasoline adsorption deep desulfurizing agent provided by the invention has the advantages of relatively high desulfurizing depth, high selectivity, no octane value loss and flexibility, simplicity and convenience for operation.

Description

technical field [0001] The invention relates to the field of gasoline desulfurization, in particular to a loaded hydroxide highly selective gasoline adsorption depth desulfurizer and a preparation method thereof. Background technique [0002] Gasoline for vehicles emits a large amount of pollutants to the environment during the combustion process, such as SO2, NOx and particulate matter PM2.5 emissions, which cause serious pollution to the environment. Gasoline quality requirements are becoming more and more stringent. In 2009, EU regulations restricted the sulfur content of motor gasoline to less than 10 μg / g (Euro V standard). my country has fully implemented the sulfur content of no more than 10 μg / g nationwide on January 1, 2017. How to effectively produce ultra-low sulfur gasoline has become an important research topic for global petrochemical companies. [0003] At present, the gasoline desulfurization technology mainly used in refineries is hydrodesulfurization. The ma...
