  • 摘要: 随着经济发展和能源需求不断增加,资源合理配置显得尤为重要。以天然气为原料的甲醇制烯烃(MTO)技术的发展,为弥合日益扩大的低碳烯烃供需矛盾提供了一条可替代传统石油化工路线、有广阔应用前景的合成路径。酸性调节对MTO催化剂的催化性能及积碳问题的解决至关重要。本研究通过改变Ca含量调节催化剂的酸性并测定系列Ca改性HZSM-5催化剂(9 ≤ Ca/Al ≤ 54)的甲醇转化率和低碳烯烃选择性以及催化剂稳定性,研究了Ca含量对150 nm Si/Al比为230的HZSM-5纳米颗粒催化甲醇制烯烃性能及积碳生成的影响。利用阳离子引入策略调节Lewis酸和Bronsted酸的比例及酸强度,研究了不同Ca离子含量对HZSM-5催化剂催化MTO转化的影响。首先,合成NaZSM-5纳米颗粒并通过离子交换法制备HZSM-5分子筛,然后采用浸渍法制备不同Ca/Al比的Ca-HZSM-5催化剂。其次,分别在390、440以及490 ℃温度条件及不同的空速条件下对常压固定床中系列Ca改性HZSM-5催化剂进行催化性能测试。在490 ℃的温度条件及空速为9 h−1条件下对HZSM-5催化剂和Ca27-HZSM-5催化剂进行了约100 h的稳定性测试。采用配备HP-Plot Q 色谱柱 (30 m × 0.53 mm × 40 μm)、FID检测器的气相色谱仪(Agilent 7890)在线分析气相产物并通过室温冷凝对液相产物进行离线分析。最后,利用XRD、BET、FESEM、IR、NH3-TPD、TGA手段对Ca改性HZSM-5催化剂进行表征,探究催化剂的构成和催化剂催化性能以及催化剂积碳失活之间的关系。从该系列Ca-HZSM-5催化剂催化性能结果结合系列表征结果可以看出,Ca含量对甲醇制烯烃反应及积碳生成影响结果如下:(1)通过调节Ca含量,可获得催化MTO反应性能最佳的Ca27-HZSM-5 (Ca/Al = 27)催化剂,该催化剂在490 ℃反应条件下的乙烯产率为0.11,丙烯产率为0.14。通过FT-IR、吡啶红外吸附以及 NH3-TPD结果分析可得,Ca27-HZSM-5催化剂在该类Ca改性催化剂中具有最多的易接触Lewis酸性位点,同时Lewis酸在总酸位点中占比最大并且酸强度也有所增强。(2)通过热重分析及反应后催化剂颜色变化可以推断Ca掺杂的HZSM-5催化剂可显著降低催化剂上积碳的生成。(3)Ca掺杂HZSM-5催化剂上其低碳烯烃产率在研究温度范围内不受温度变化的影响并且该Ca掺杂HZSM-5催化剂相较于未掺杂的HZSM-5催化剂乙烯和丙烯的产率得到了提高。(4)适当的Ca掺杂HZSM-5催化剂上较轻的芳香碳在积碳中的占比较大。通过引入阳离子调节分子筛催化剂的酸性是优化该类催化剂催化脱水反应的有效手段。基于此,本研究通过掺杂Ca阳离子优化了HZSM-5分子筛催化MTO反应的性能。由于Ca掺杂,降低了催化剂的酸性从而抑制了质子转移反应并显著降低了催化剂酸位点上齐聚反应的进行进而抑制芳烃循环路径低碳烯烃的生成。适当数量的Ca掺杂,由于最弱的空间位阻效应,暴露出更多易接触Lewis酸位点使得该催化剂具有良好的活性和较高的低碳烯烃选择性。在研究的温度范围内,Ca掺杂HZSM-5催化剂催化MTO反应的能垒降低。同时Ca掺杂可适当降低积碳的生成速率,长时间进行催化反应仍会导致积碳的生成。
