Abstract

The invention relates to active boron nitride, in particular to active boron nitride, a preparing method of the active boron nitride and application of the active boron nitride to adsorption for reducing content of sulfur in fuel oil. A surface active agent is dissolved in a mixed solution of water and methyl alcohol, then boric oxide and a nitrogen source are dissolved in the above solution, stirring is conducted at the temperature ranging from 50 DEG C to 90 DEG C for evaporation, and after all the solution is evaporated, an obtained solid is placed in a tubular furnace, high temperature roasting is conducted for 5 h in the nitrogen or ammonia atmosphere, and the active boron nitride with the high specific surface area is obtained. The invention provides a novel active boron nitride adsorbent, the specific surface area is large, the adsorption activity is high, and sulfide in the fuel oil can be efficiently removed with low energy consumption. Meanwhile, the preparing method is simple, and cost is low.

Description

technical field [0001] The invention relates to active boron nitride, in particular to an active boron nitride, a preparation method thereof and an application for reducing sulfur content in fuel oil by adsorption. Background technique [0002] In recent years, China's environmental pollution has become increasingly serious, a considerable part of which is due to the poor quality of fuel in China for many years. The sulfur content in fuel is the most critical environmental protection indicator in motor vehicle fuel. The use of high-sulfur fuel will not only increase the emission of toxic sulfur oxides, but also reduce the efficiency of the vehicle's own emission reduction components, resulting in increased emissions of carbon monoxide, nitrogen oxides and other substances. These all happen to be important ingredients in the formation of smog. Reducing the sulfur content in fuel oil, improving fuel quality, and alleviating environmental pollution are the main purposes of fu...
