Embodiment 1

[0044] With silicon aluminum (SiO 2 :Al 2 o 3 , mol) ratio of 60 NaZSM-5 powder X to prepare powdery HZSM-5 molecular sieve, and prepare powdery Pt / HZSM-5 molecular sieve catalyst by the following method:

[0045] (1) The Na-type molecular sieve powder X is mixed with 1mol / L NH 4 NO 3 The solution was exchanged 5 times at 80°C, washed with water, dried, calcined at 450°C, and converted into H-type molecular sieves;

[0046] (2) Weigh 50 g of H-type molecular sieve prepared in step (1), add 200 ml of tetraammine platinum nitrate (II)-2m% ammonia solution containing 163 mg / L of platinum, and immerse for 8 hours. Stir once every 10 minutes for 2 hours before immersion. Stir once every hour, filter with suction, add 80ml of water to the funnel each time, soak for 5min and then filter with suction, wash 4 times in total; the collected filtrate and washing liquid are combined to a total of 310ml; dilute the filter cake on a glass watch glass, and place it in an oven at 120°C Dr...

Embodiment 2

[0051] Substantially repeat the steps (2)-(3) of Example 1 to prepare the Pt / HZSM-5 molecular sieve catalyst of loaded metallic platinum, the difference is that step (2) adds tetraammine platinum (II)-2m% ammonia solution Containing platinum 260mg / L, immersion time 12h, step (3) is treated at 300°C and flowing dry nitrogen flow.

[0052] Step (2) The platinum exchange rate in the catalyst preparation process is 93%, and the platinum content of the prepared powdery Pt / HZSM-5 molecular sieve catalyst is calculated to be 0.096m%.

Embodiment 3

[0054] Substantially repeat the steps (2)-(3) of Example 1 to prepare the Pt / HZSM-5 molecular sieve catalyst of loaded metal state platinum, the difference is that directly adopt powdery HZSM-5 molecular sieve Y as raw material, silicon aluminum (SiO 2 :Al 2 o 3 , mol) ratio of 120; SEM photos show that the crystal grains are strip-shaped, the crystals are complete, the overall size is 1-3 μm, and there is no microcrystalline aggregate. The SEM statistical software measures that the number of crystal grains of 0.8-5 μm accounts for the total number of crystal grains. 98.1%, less than 0.5% below 0.5μm; XRD measurement crystallinity 95%; low temperature nitrogen adsorption method specific surface area 360m 2 / g; the specific surface area of ​​pores with a diameter of 10nm or more measured by mercury intrusion porosimetry is 0.77m 2 / g, as the specific surface area of ​​the outer surface of molecular sieve grains.

[0055] The tetraammine platinum (II) nitrate-2m% ammonia solu...

Abstract

The invention provides a gasoline octane number increasing agent with lower use costs, no ash, no banned substance and better effects and a preparation method of the increasing agent. The increasing agent comprises the following active ingredient: bis(alkylphenyl)butane; and the increasing agent is prepared by the steps of performing a reaction on raw materials including butanone and a C7-C10 aromatic hydrocarbon under the action of a Pt / HZSM-5 molecular sieve catalyst, performing a reaction under the action of a Pt / Hbeta molecular sieve catalyst, and allowing the obtained liquid product to bedirectly used as the gasoline octane number increasing agent, or performing separation to remove the raw material components or intermediate components to be used as the gasoline octane number increasing agent.

Description

technical field [0001] The invention belongs to the technical field of gasoline additives, and in particular relates to a preparation method of a gasoline octane number enhancer. Background technique [0002] The mandatory national standard GB17930-2016 stipulates that in national V, national VIA, and national VIB motor gasoline, the additives used should have no recognized harmful effects, and should be used according to the recommended dosage, and no artificial addition of methylal, aniline and Compounds containing halogen, phosphorus, silicon, etc., shall not be artificially added with additives containing lead, iron and manganese. [0003] The mandatory part of GB18351-2017 ethanol gasoline (E10) for vehicles, i.e. the requirements and test methods in Chapter 5, stipulates that the additives used in ethanol gasoline (E10) for National V, National VIA and National VIB should have no recognized harmful substances. function, and use it according to the recommended dosage, ...
