Several nickel complexes [N,N]NiBr_2, in which [N,N] indicates bidentatenitrogen-containing ligands (1: [N,N]=N-(2,6-diisopropylphenyl)pyridine-2-carboxaldimine(C_(18)H_(22)N_2); 2: N-(2,6-diisopropylphenyl)-6-methylpyridine-2-carboxaldimine (C_(19)H_(24)N_2);3: N-(2,4,6-trimethylphenyl)pyridine-2-carboxaldimine(C_(15)H_(16)N_2); 4:N-(2,4,6-trimethylphenyl)-6-methylpyridine-2-carboxaldimine (C_(16)H_(18)-N_2) were *** of the nickel complexes exhibit high activity for ethylene oligomerizatiori in the presence ofan organoaluminum activator. The main factor affecting the activity and the structure of oligomersis the steric effect of substituents on [N,N] ligands. Methylaluminoxane (MAO) -activated catalystsshowed higher activities and produced oligomers with higher molecular weight than Et_2AlCl-activatedones. The oligomerization in toluene rather than hexane results in much higher activity, and theoligomers produced in toluene have relatively high molecular weight. With activation of MAO orEt_2AlCl, the [N,N]NiBr_2 system tended to produce highly branched oligomers with low α-olefincontent, but the α-olefin content could be increased by changing the reaction conditions.

生活垃圾的焚烧处理是目前我国主流技术之一,而生活垃圾焚烧(municipal solid waste incineration,MSWI)处理必然会伴随着飞灰的产生。《国家危险废物名录(2021年版)》明确MSWI飞灰为危险废物,其安全处理与处置问题是“无废城市”建设过程中的“最后一公里”。MSWI飞灰相关政策标准的实施,促使飞灰管理体系科学且规范。根据不同时期MSWI飞灰相关政策标准的实施情况,将其分为探索起步阶段(以填埋为主)和全面提升阶段(以水泥窑协同处理为主,探索其他资源化方式共存),并对飞灰处置趋势进行展望,其中制备免烧建筑材料是最具前景的发展方向之一。未来飞灰处置趋于区域产业化、标准体系化、减量化、高值化和多元资源化,可为“无废城市”建设提供技术和产业支撑。
