Embodiment 1

[0017] Take 11kg of 1-hexylpiperidin-4-ol, 24kg of N-hexyl-N-vinylformamide, 19kg of cis-3-hexenol 2-methylbutyrate, 1,5-hexadiene-3 , 16kg of 4-diol, 14kg of 1-methylhexahydro-4H-azepine-4-one and 16kg of lithium acetoacetate were added to the stirring tank, and stirred evenly at room temperature to obtain transparent and clear alcohol-based fuel sulfur dioxide reduction Emission of finished additives.

[0018] Add 4kg of the additive of this example to 900kg of crude alcohol, mix evenly, and treat it with a BMT-180 ultrasonic instrument of BRANSON in the United States for 20 minutes at room temperature, then add 96kg of conventional additives for other alcohol-based fuels to obtain an alcohol-based fuel.

[0019] Twelve kinds of crude alcohols from all over the country were selected as basic raw materials to prepare two groups of 24 alcohol-based fuel samples. Among them, the first group is a blank control group that uses 12 kinds of crude alcohol raw materials without addi...

Embodiment 2

[0024] Take 16kg of 1-hexylpiperidin-4-ol, 15kg of N-hexyl-N-vinylformamide, 17.5kg of cis-3-hexenol 2-methylbutyrate, 1,5-hexadiene- Add 15.5kg of 3,4-diol, 20kg of 1-methylhexahydro-4H-azepine-4-one and 16kg of lithium acetoacetate into the stirring tank, and stir evenly at room temperature to obtain transparent and clear alcohol-reduced Finished additives for fuel sulfur dioxide emissions.

[0025] Add 4kg of the additive of this example to 800kg of crude alcohol, mix evenly, and treat it with the BMT-180 ultrasonic instrument of BRANSON in the United States for 20 minutes at room temperature, and then add 196kg of conventional additives for other alcohol-based fuels to obtain alcohol-based fuel.

[0026] Carry out test according to embodiment 1 method, detection result is as follows.

[0027]

Embodiment 3

[0029] Take 21kg of 1-hexylpiperidin-4-ol, 16kg of N-hexyl-N-vinylformamide, 15kg of cis-3-hexenol 2-methylbutyrate, 1,5-hexadiene-3 , 12kg of 4-diol, 16kg of 1-methylhexahydro-4H-azepine-4-one and 20kg of lithium acetoacetate were added to the stirring tank, and stirred evenly at room temperature to obtain transparent and clear alcohol-based fuel sulfur dioxide reduction Emission of finished additives.

[0030] Add 4kg of the additive of this example to 950kg of crude alcohol, mix evenly, and treat it with a BMT-180 ultrasonic instrument of BRANSON, USA for 20 minutes at room temperature, then add 46kg of conventional additives for other alcohol-based fuels to obtain alcohol-based fuel.

[0031] Carry out test according to embodiment 1 method, detection result is as follows.

Abstract

The invention discloses an additive for reducing sulfur dioxide discharge of alcohol-based fuel; the additive for reducing sulfur dioxide discharge of alcohol-based fuel consists of the following constituents by mass percentage: 10% to 32% of 1-hexyl piperidine-4-alcohol; 9% to 30% of N-hexyl-N-vinylformamide; 12% to 26% of cis-3-hexenol-2-methylbutyrate; 10% to 32% of 1,5-hexadiene-3,4-glycol; 12% to 30% of 1-methylhexahydro-4H-azepine-4-ketone; 15% to 32% of lithium acetoacetate. Sulfur dioxide generated by combustion of alcohol-based fuel can be greatly reduced by adding 0.4 wt% to 0.8wt% of the disclosed additive into the alcohol-based fuel; therefore, the sulfur dioxide discharge in boiler fume can be averagely reduced by about one third.

Description

technical field [0001] The invention belongs to the technical field of alcohol-based fuel replacing boiler fuel, and relates to an additive for alcohol-based fuel, in particular to an additive capable of reducing the emission of sulfur dioxide from alcohol-based fuel. Background technique [0002] Energy utilization is the main cause of air pollution. In my country's energy utilization structure, coal with serious pollution accounts for about 70% of the total energy consumption. Various fuels are burned in boilers and other combustion devices, producing a large amount of soot, sulfur oxides, nitrogen oxides, carbon monoxide, hydrocarbons and other pollutants. Thermal power generation, metallurgy, chemical industry, building materials, hospitals, schools and other enterprises and institutions and urban residents are equipped with industrial boilers or domestic heating boilers, especially small boilers, which are large in number, widely distributed, and have poor firing condit...
