本文研究了在转移加氢条件下,不同类型醇作为氢供体对镍基催化剂在苯并呋喃加氢反应中的活性影响.结果表明,使用异丙醇作为氢供体时,苯并呋喃的加氢过程为底物先发生脱芳构化,然后再进行脱氧反应.然而,当使用伯醇如甲醇、乙醇和正丙醇作为氢供体时,会导致镍基催化剂的不可逆失活.针对这一现象,进一步研究了伯醇使镍基金属催化剂失活的机理.结果表明,在250°C条件下,催化剂与伯醇的相互作用会导致形成非活性的碳化物Ni_(3)C,并且镍金属颗粒在氧化铝载体表面会发生烧结和偏析.

快速城镇化进程中,人口大规模流失引发乡村人地关系失衡,加剧了村庄空心化问题。科学测度乡村空心化、提出以乡村振兴为导向的空心村整治策略,具有重要的现实意义。论文以黑龙江省拜泉县为例,基于人口转移率测度了乡村空心化水平,运用熵权TOPSiS法评价了村庄发展潜力水平,将二者结合识别了村庄发展类型,提出差异化的空心村整治策略。研究结果显示:(1)拜泉县乡村空心化水平均值为0.6529,空心化程度明显。乡镇层面的空心化处于中度和高度水平,村庄以高度和重度空心化为主。农村人口流失主要归因于城乡建设不均衡、农村就业机会少、农村社会保障水平偏低等。(2)村庄发展潜力均值为0.2279,整体水平偏低且空间分布差异明显,县城周边、沿主要交通干线以及主要河流的村庄发展潜力水平普遍高于偏远地区的村庄。产业兴旺(0.5026)水平显著高于乡风文明(0.2703)、生态宜居(0.1472),治理有效(0.0317)、生活富裕(0.0482)水平较低,成为村庄发展潜力的短板。(3)拜泉县村庄类型划分为Ⅰ类——高潜力低空心化、Ⅱ类——高潜力高空心化、Ⅲ类——低潜力低空心化、Ⅳ类——低潜力高空心化4类,整体以Ⅱ类——高潜力高空心化为主,且县域南部村庄发展状态好于北部地区。未来村庄发展应以乡村振兴战略为指引,重心向Ⅰ类、Ⅱ类以及南部村镇转移,并完善宅基地、生态用地、耕地等相关制度体系,促进村庄内部结构调整;培育合作社、家庭农场等新型经营主体,探索特色产业规划与升级道路;构建“中心镇—中心村—农民社区—村庄”的新型村镇体系,加强城乡互动,促进要素聚集、资源共享;同时加大环境整治,增强社会保障,吸引人才回归,实现空心化治理与县域乡村振兴。
