Problems solved by technology

[0005] Although ethanol gasoline has been used as a vehicle fuel for many years in many countries, it has been semi-mandatoryly promoted in many areas in China in the past ten years. In September 2017, 15 departments including the National Development and Reform Commission and the National Energy Administration also jointly issued the " The Implementation Plan on Expanding the Production of Biofuel Ethanol and Promoting the Use of Ethanol Gasoline for Vehicles requires that the use of ethanol gasoline for vehicles be promoted nationwide in 2020 and basically achieve full coverage, and that the promotion of ethanol gasoline be used as a national strategic measure. In order to optimize the energy structure, improve the ecological environment, regulate the grain market, ensure national food security, and improve the technical level of comprehensive utilization of agricultural and forestry waste resources; problems, making it more difficult and costly to popularize and apply

Embodiment 1

[0024] 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:

[0025] (1) The Na-type molecular sieve powder X is mixed with 1mol / L NH 3 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;

[0026] (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

[0031] 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.

[0032] 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

[0039] In a 1000ml three-necked flask, add 144.2g (2mol) of methyl ethyl ketone, 368.4g (4mol) of toluene, add 20g of powdery Pt / HZSM-5 molecular sieve catalyst with a platinum content of 0.062m% prepared in Example 1, put a stirring bar, and install Temperature control and reflux, control the temperature of the slurry at 60°C and react for 80 hours; during the reaction process, take a sample every 5 hours, stop stirring and settle the catalyst before sampling, and take no more than 30 μl of each sample, and use gas chromatography for detection; the result is butanone The conversion rate is 80%; the conversion rate of butanone is 83% and the conversion rate of toluene is 39% when the reaction is 80h, and the selectivity of butanone to 2-(p-methylphenyl)-2-butanol is 76%; after the reaction, the slurry cools down and settles , the extracted supernatant is the liquid product L301 of this embodiment.

[0040] Detect the composition of the obtained liquid product L301, in 100g, co...

Abstract

The invention provides an ethanol gasoline dispersing agent and ethanol gasoline containing thesame. The ethanol gasoline is not liable to be layered, gasoline consumption is low, power performance ishigh, engine noise is low, carbon deposition is not liable to occur, and using and popularizing are easy. The ethanol gasoline dispersing agent is prepared from the following effective components ofalkyl-phenylbutanol, diethyl malonate and selectable octanol, and the addition quantity of the ethanol gasoline dispersing agent in the ethanol gasoline based on the effective components is 0.1-0.5%.

Description

technical field [0001] The invention belongs to the technical field of clean gasoline, and in particular relates to an ethanol gasoline dispersant and ethanol gasoline containing the dispersant. Background technique [0002] It is generally believed that ethanol gasoline is a clean fuel. The octane number (RON) of ethanol is 106, and it can be mass-produced by bio-fermentation from expired corn and agricultural and forestry waste such as straw. Adding ethanol to gasoline can avoid the harm to the environment and human body caused by adding MTBE and other components. After using ethanol gasoline, the emissions of CH, CO, fine particles and other harmful substances from the engine are reduced, which helps to reduce the pollution of automobile exhaust and improve air quality. [0003] The gasoline components of ethanol gasoline are processed from petroleum, basically non-polar hydrocarbons, and have poor compatibility with certain polar ethanol, so it is necessary to add a di...
