摘要
为提高吸热型碳氢燃料的吸热能效,将辅助燃料Y按不同比例与碳氢燃料混合,配制成新的混配型YNNJ-150燃料,利用连续流吸热型碳氢燃料裂解微型反应色谱评价装置,考察了它的热裂解转化率和低碳烯烃的选择性,并在HZSM-5分子筛上进行了催化裂解评价。结果表明混配型YNNJ-150燃料不仅降低了裂解温度,同时提高了燃料裂解的低碳烯烃的选择性,增加了燃料的吸热能力,且混合辅助燃料Y的比例为15％时的混配燃料Y_cNNJ-150的效果最好。混配型燃料可成为今后研究的一个重要方向。
In order to improve the endothemitic capability of endothermtic hydrocarbon fuels, new YNNJ-150 fuel was prepared by adding Y additive to NNJ-150. Cracking conversion and selectivity of light carbon olefins of mixing endothermic hydrocarbon fuels was investigated by the microreactive chromatogram installation. Results show that the mixing YNNJ-150 not only decreases the temperature of cracking, but also improves the selectivity of light olefins and endothermic capability. Mixing fuel of containing percent 15 Y is best in all different proportions. Cracking performance of mixing fuel on HZSM-5 was further studied. The mixing endothermic hydrocarbon fuels may be the focus of future research.
