合成气直接制取低碳烯烃的铁基负载型催化剂的制备与性能

Preparation and Properties of Iron-based Supported Catalyst for Direct Synthesis of Light Olefins from Syngas

化工产业是国民经济支柱产业之一,低碳烯烃既是石油化工产业的重要产品,也是现代工业工艺的重要基础原料。从化工生产层面分析,低碳烯烃是人造纤维、合成塑料和多种化工材料的重要"中间体",其来源主要通过石脑油裂解,客观上对石油能源的需求量较大。然而我国是典型的"贫油多煤"能源结构,通过合成气直接制取低碳烯烃具有重要的意义。

The chemical industry is one of the pillar industries of the national economy. Low-carbon olefms are not only important products of the petrochemical industry, but also important basic raw materials for modem industrial processes. From the aspect of chemical production, low-carbon olefins are important intermediates for man-made fibers, synthetic plastics, and various chemical materials. Their sources are mainly cracked by naphtha, and the demand for petroleum energy is objectively larger. However, China is a typical ＂lean oil and coal＂ energy structure. It is of great significance to directly produce low-carbon olefins from syngas.
