摘要
以石油焦为原料 ,采用自制活化剂制备天然气炭质吸附剂 ,采用静态低温氮吸附容量法对吸附剂进行有关结构参数的测定。并用自制的吸附评价装置 ,采用质量法对吸附剂的有效贮气量进行测定。实验考察了活化剂用量、活化温度和活化时间对吸附剂结构参数的影响。并把吸附剂制备工艺条件与其结构及贮气性能进行了有益的关联。实验结果表明 ,活化剂用量、活化温度和活化时间都决定着活化反应的深度。在影响单位体积吸附剂贮气性能的几个要素中 。
Natural gas porous carbon adsorbents were prepared from petroleum coke using chemical activation.Structure and adsorptive capacity of the adsorbents were characterized respectively by ASAP2010 apparatus and gravitational equipment Effects of activation temperature, temperature holding time and activation agent ratio on the structure of adsorbents were investigated Relations between adsorption capacity, structure and preparation of adsorbents were tentatively speculated Results indicated that activation temperature, temperature holding time and activation agent ratio determined the depth of activation and the micropore distribution Of the factors affecting adsorptive capacity of adsorbents, the micropore of 0 85nm diameter is quite important.
