Abstract

The invention relates to a polyaniline coated biological carbon material, and an application thereof in the preparation of a solid alkali. A preparation method of the polyaniline coated biological carbon material comprises the following steps: (1) taking dried sweet potato leaves, heating the dried sweet potato leaves to 600-700 DEG C under the protection of nitrogen, carbonizing the heated sweetpotato leaves for 5-6 h, and naturally cooling the carbonized leaves to room temperature to obtain a biological carbon material; and (2) ultrasonically soaking the biological carbon material obtainedin step (1) in a hydrochloric acid solution for 4-5 h, adding aniline, adding an ammonium persulfate solution in ice bath, continuously performing a reaction in the ice bath for 6-10 h, filtering theobtained reaction solution, and washing and drying the obtained precipitate to obtain the polyaniline coated biological carbon material.

Description

technical field [0001] The invention belongs to the field of biodiesel catalysts, and in particular relates to a polyaniline-coated bio-carbon material and its application in preparing solid alkali. Background technique [0002] Biodiesel has become a research hotspot in various countries because of its environmental friendliness and renewability. Biodiesel uses vegetable oil, animal fat oil, waste cooking oil, etc. as raw materials, and performs transesterification with low molecular weight alcohols to obtain fatty acid alkyl monoesters. Its properties are very close to those of mineral diesel, and it is a renewable clean fuel. Although there are many methods for preparing biodiesel, large-scale industrial production still uses traditional homogeneous catalysis such as liquid acid and alkali, and the commonly used homogeneous catalysts include CaO, H 2 SO 4 , NaOH, etc., which seriously corrode the equipment, and the products need to be neutralized and washed, resulting i...
