Problems solved by technology

[0006] The desulfurization methods reported in the above literature generally have complex processes and general sulfur removal effects, especially when the adsorbent reaches a saturated state, it must be replaced, and the replacement of the adsorbent is expensive to reuse, and generally cannot be reused, causing secondary pollution
Furthermore, the impregnation time of adsorption desulfurization is long, and the gasoline is turbid and needs to be precipitated, and gasoline is volatile and wastes oil resources.

Embodiment 1

[0023] Embodiment 1, a kind of production method that extracts inorganic liquid alkali from natural plant winter grass as sulfur scavenging agent, uses natural plant winter grass as raw material, adopts distillation technology, extracts inorganic liquid alkali from natural plant winter grass as sulfur scavenging agent . Contains the following process steps:

[0024] 1) After the leaves of Dongmao are cut off, the stems and leaves are stacked separately.

[0025] 2) Cut the Dongmao stalk in half.

[0026] 4) Cut the winter stalks and leaves of winter stalks into suitable lengths.

[0027] 6) Mix the cut winter stalks and winter stalks.

[0028] 7) the mixed winter grass stalk and winter grass leaves are packed into the distillation machine.

[0029] 8) Start the distillation machine, and after being heated, the alkalinity of the winter grass is separated from the winter grass and flows out from the distillation machine to obtain an inorganic liquid alkali sulfur scavenger. ...

Embodiment 2

[0030] Embodiment 2, referring to Table 1, after the sulfur scavenger of the present invention is mixed with 93# gasoline, adopt the automatic smoke dust (gas) tester (08 generation) instrument of Lao Ying 3012H type, to the discharge of license plate Xiang A8ES19 Wuling Rongguang small ordinary passenger car The sulfur dioxide in the tail gas was tested 5 times. As can be seen from Table 1, the effect of the sulfur eliminating agent provided by the present invention is remarkable, and the sulfur dioxide emitted from the automobile tail gas is 0 when the sulfur eliminating agent is added to 2%.

[0031] Table 1 Sulfur dioxide test results Unit: mg / m3

[0032] Note: Add 0.5%, 1%, 1.5%, and 2% of sulphur-killing agents (volume percentage) to 93# gasoline.

Abstract

The invention relates to a production method for extracting inorganic liquid base from natural plant winter cogongrass to serve as a desulfurizing agent, as well as applications. The production method of the desulfurizing agent comprises the following step: by taking natural plant winter cogongrass as a raw material, extracting inorganic liquid base from natural plant winter cogongrass to serve as the desulfurizing agent by adopting distillation technology. For the applications of the desulfurizing agent in a locomotive, a certain amount of the desulfurizing agent is doped into gasoline or diesel locomotive fuel and fully stirred evenly, and the emission amount of sulfur dioxide in the tails gas generated by the gasoline locomotive can be eliminated or reduced. The production method belongs to energy-saving and emission reduction technology, thus having great social and economic values.

Description

technical field [0001] The present invention relates to the production method and application technical field of sulfur scavenging agent, specifically refers to a production method of extracting inorganic liquid alkali from natural plant P. Applications. Background technique [0002] With the increase of the processing capacity of high-sulfur crude oil, the sulfur content in oil products also increases accordingly, and the environmental pollution is aggravated, which has aroused widespread concern in various countries. In developed countries, the gasoline specification control index is to limit the gasoline sulfur content to less than 50ppm, and the diesel specification control index is to limit the diesel sulfur content (mass fraction) to less than 0.05% by weight. At present, my country requires that the sulfur content of gasoline products is less than 800ppm, and that the sulfur content of diesel products is not higher than 0.2 wt%. The more effective way to reduce the ...
