Abstract
The invention relates to a resin-based activated carbon ball and a preparation method thereof, belonging to the technical field of high polymer materials. The resin-based activated carbon ball is prepared from the following materials according to parts by weight: 10-15 parts of m-ethyl phenol, 20-55 parts of formaldehyde, 5-9 parts of triethylamine, 80-120 parts of deionized water, 3-8 parts of polyvinyl alcohol, 10-20 parts of melamine and 10-25 parts of inorganic salt. According to the invention, spherical phenolic resin is synthesized first so as to be used as basic resin for preparing resin-based activated carbon, and then, the resin-based activated carbon is prepared at high temperature under protection of nitrogen. Compared with powdery and granular activated carbon, the spherical activated carbon becomes an adsorptive desulfurizing agent with excellent performance depending on the characteristics of smooth surface, suitable ball diameter and good mobility.
Description
Technical field [0001] The present invention involves a activated carbon and its preparation methods. More specifically, the invention involves a resin -based activated carbon ball and its preparation method, which is a high molecular material technology field. technical background [0002] Activated carbon has the characteristics of cheap raw materials, higher surface area, large Kong Rong, and easy regeneration, which are widely used to adsorb desulfurization.At present, activated carbon research mainly includes the following aspects: First, the impact of hole structure on adsorption performance. The use of polystyrene activated carbon balls to adsorb DBT in the simulation oil. The DBT capacity is 109.36mg / g.There is a good correlation between the holes (0.7nm) of the holes (the aperture diameter <0.7nm), and there is no correlation between the comparison surface area of the activated carbon ball and the total Kong Rong.Second, the activated carbon surface loaded metal oxide...
