Abstract

The present invention relates to a porous imprinting carbon nano-sphere preparation method, which comprises adopting a glucose solution to carry out hydrothermal synthesis of carbon nano-spheres, and carrying out surface modification, sintering carbonization, and grafting modification on the porous carbon nano-spheres to finally prepare the porous imprinting carbon nano-spheres. The preparation method has characteristics of rigorous process, advancement, reasonability, and accurate and detailed data. The product has the following characteristics that: a morphology is good, the product is black round particles, a particle diameter is less than or equal to 180 nm, a porous imprinting effect is significant, the product can be matched with a plurality of chemical substances, product purity is good and achieves 99%, and a yield is high and achieves 91%. In addition, the preparation method is an ideal porous imprinting carbon nano-sphere preparation method.

Description

technical field [0001] The invention relates to a method for preparing porous imprinted carbon nanospheres, belonging to the technical field of surface chemical modification and application of carbon-organic composite materials. technical background [0002] In view of the requirements of deep desulfurization of oil products, it is very important to remove sulfur-containing substances such as thiophenes, mercaptans, and sulfides in oil products. Traditional desulfurization methods are very difficult for the removal of thiophene and its derivatives. Therefore, It is particularly important to study new environmentally friendly desulfurization technologies. [0003] Over the years, although the deep desulfurization of oil has made great progress, it still cannot get rid of the situation of high temperature, high pressure, high energy consumption and heavy pollution. , stable, green, low cost, low energy consumption, renewable, with predetermined structure and activity, specifi...
