摘要：本课题通过对活性炭表面进行改性，探究负载单组份金属盐和金属氧化物对活性炭的脱硫性能的影响，结果表明，负载金属对提高活性炭表面活性位点活性有利，同时对硝酸氧化的活性炭进行负载金属，脱硫效果表明硝酸氧化对脱硫硫容的提高有利，含氧官能团的数目对脱硫效果有促进作用，同时金属对提高活性位点活性有利，对不同浸渍方式得到的双金属活性炭脱硫效果表明，配制浸渍溶液时的溶剂及络合剂与金属离子作用的分子越小对脱硫效果越有利，通过相同的浸渍方式不同的金属量进行脱硫结果表明金属量越多，越易导致金属堆积成块，导致活性位点活性虽然强，但是数目减少，同时会堵塞活性炭的微孔对DBT分子的吸附造成负面影响，从而导致硫容的下降。24500

Study on the synthesis and properties of fuel desulfurization
by activated carbon supported nickel zinc bimetallic system
Abstract ： This topic through the activated carbon surface modification, inquiring the Effects of
load component metal salt and metal oxide desulfurization properties of activated carbon, it’s
showed that, supported metal is beneficial to improve the activated carbon surface active sites
of activity, and activated carbon on the nitric acid oxidation to load metal, desulphurization
effect indicates that nitric oxide is beneficial to increase the desulfurization of sulfur capacity,
the number of oxygen containing functional groups has a promoting effect on desulphurization
effect, at the same time to improve the activity of metal active sites, show that the double metal
activated carbon desulfurization effect obtained by different impregnation methods, molecular
solvents and complexing agent and metal ions in the preparation of impregnating solution, the
smaller the molecule is, the better for the desulfurization effect, the amount of metal by means
of soaking of different desulphurization results show that more metal quantity is, it will more
easily lead to the accumulation of metals into blocks, leading to the active site activity although
strong, decreased in number, at the same time Has a negative impact when activated carbon
adsorption pore blockage of the DBT molecule, which leads to a decrease in sulfur capacity.
