Abstract

This work considers new possibilities for the use of membrane gas separation technology for target control of the composition of synthesis gas. For this purpose, we propose using highly permeable modified disubstituted polyacetylenes with an improved combination of selectivity of separation of hydrogen, carbon monoxide, and carbon dioxide and a high level of transfer of hydrogen as the main component of synthesis gas. This work presents the description of the modification of polymers and key properties of membrane materials. The process of membrane separation of synthesis gas is modeled using both commercially available membranes and new laboratory membranes. The possibility of creating a combined membrane system providing the preparation of synthesis gas with a wide range of H₂ : CO ratios (from 0.5 to 4) and a low residual concentration of CO₂ (5 vol %) from biosyngas with the composition H₂ (40 vol %)/CO (25 vol %)/CO₂ (35 vol %) is also shown.

基于改性的1,2-二取代聚乙炔的膜对合成气组成的膜控制

摘要

这项工作考虑了使用膜式气体分离技术对合成气组成进行目标控制的新可能性。为此，我们建议使用具有高渗透性的改性二取代聚乙炔，并将氢，一氧化碳和二氧化碳的分离选择性与高水平的氢转移作为合成气的主要成分。这项工作介绍了聚合物的改性和膜材料的关键特性的描述。使用市售膜和新型实验室膜对合成气的膜分离过程进行建模。创建组合膜系统的可能性，以制备具有多种H ₂的合成气：具有H ₂（40％体积）/ CO（25％体积）/ CO ₂（35％体积）组成的生物合成气中的CO比率（0.5至4）和低残留浓度的CO ₂（5％体积）为也显示。
