The continuous demand for olefins has stimulated recent research to develop appropriate technology to produce olefins from alternative resources. Syngas-to-olefins (STO) is considered to be a promising pathway due to the availability of numerous technologies to produce syngas from municipal solid waste and biomass. The development of catalysts to obtain high CO conversion and high selectivity to olefins is still in progress. The first route is based on iron and cobalt catalysts via Fischer Tropsch synthesis to olefins (FTO) with a range of promising supports and promoters. The second approach is based on metal oxide–zeolite (OX–ZEO) composites, with a focus on combined metal oxides to increase the CO conversion. Finally, the potency of less-explored zeolite frameworks such as FER, KFI and Rho zeolites is highlighted. We propose that researchers should focus on FER, KFI and Rho zeolites. However, further reaction mechanism studies should be elaborated to obtain their optimum conditions for STO.

纳米结构催化剂上合成气-烯烃途径中较少探索的沸石材料的机会：小型综述

对烯烃的持续需求刺激了最近的研究，以开发合适的技术以利用替代资源生产烯烃。合成气制烯烃（STO）被认为是一种有前途的途径，因为可以利用多种技术从市政固体废物和生物质生产合成气。获得高CO转化率和对烯烃的高选择性的催化剂的开发仍在进行中。第一条路线是基于铁和钴催化剂通过费托合成烯烃（FTO）并具有一系列有前景的载体和促进剂。第二种方法是基于金属氧化物-沸石（OX-ZEO）复合材料，重点是结合金属氧化物以提高CO转化率。最后，强调了诸如FER，KFI和Rho沸石等未开发的沸石骨架的效力。我们建议研究人员应专注于FER，KFI和Rho沸石。但是，应详细研究进一步的反应机理，以获得其最佳的STO条件。
