摘要

非甲烷碳氢化合物(NMHCs)是石化工业中常见的一种挥发性有机化合物(VOCs)污染物,因其对健康的不良影响和对环境的不良影响而受到广泛关注。本文报道了一种由沸石咪唑框架-8(ZIF-8)和异十六烷形成的新型多孔浆料,用于捕集油田废气中的低浓度、多组分非甲烷有机化合物(主要是乙烷(C2H6)、丙烷(C3H8)和正丁烷(n-C4H10))。泥浆中 C2H6 的吸附能力明显高于氮气(N2)和甲烷(CH4)。此外,通过压降曲线,泥浆中 C2H6 的竞争吸附能力明显优于 N2 和 CH4。在非甲烷总烃捕获实验中,净化后的 C3H8 和 n-C4H10 浓度可降至 100 ppm 以下,而 C2H6 浓度可达到约 180 ppm。更令人鼓舞的是,在突破试验中,浆料对多组分 NMHC 具有完美的动力学分离选择性。此外,为了避免 ZIF-8 材料在酸性和潮湿环境中长期使用时结构崩溃,在材料合成过程中,浆料中保留了一定量的 2-甲基咪唑作为保护剂。这样,浆料中的 ZIF-8 材料就能在水性和酸性环境中保持稳定的特征结构,并保持对 NMHC 的捕获能力而不会降解。我们认为多孔 ZIF-8/ 异十六烷浆料是一种很有前景的低浓度、多组分 NMHC 捕捉剂,具有很强的净化能力和稳定性。

Low-concentration and multi-component NMHCs capture from oil field exhaust using porous ZIF-8/iso-hexadecane slurry

Non-methane hydrocarbons (NMHCs) are a common type of volatile organic compounds (VOCs) pollutant in the petrochemical industry and have attracted widespread attention because of their adverse health effects and environmental impacts. In this paper, we report a new porous slurry formed with zeolitic imidazolate framework-8 (ZIF-8) and iso-hexadecane to capture the low-concentration and multi-component NMHCs (mainly ethane (C2H6), propane (C3H8), and n-butane (n-C4H10)) from the oil field exhaust. The sorption capacity of C2H6 in the slurry is significantly higher than that of nitrogen (N2) and methane (CH4). Moreover, the slurry demonstrated a clear advantage for C2H6 over N2 and CH4 in competitive adsorption through the pressure-drop curves. In the NMHCs capture experiments, the C3H8 and n-C4H10 concentrations after purification can be reduced to below 100 ppm, while the C2H6 concentration can reach approximately 180 ppm. More encouragingly, in the breakthrough tests, the slurry exhibits a perfect kinetic separation selectivity for multi-component NMHCs. Furthermore, to avoid structural collapse of ZIF-8 material during long-term use in acidic and wet environments, a certain amount of 2-methylimidazole was retained in the slurry as a protective agent in the material synthesis process. In this way, the ZIF-8 materials in the slurry can retain the stable characteristic structure in an aqueous and acidic environment and keep the capture capacity for NMHCs without degradation. We believe the porous ZIF-8/iso-hexadecane slurry is a promising capture agent for low-concentration and multi-component NMHCs with strong purification capacity and stability.
