Abstract

Hydrate-based CO2 sequestration (HBCS) emerges as a promising solution to sequestrate CO2 as solid hydrates for the benefit of reducing CO2 concentration in the atmosphere. The natural conditions of high-pressure and low-temperature in marine seabed provide an ideal reservoir for CO2 hydrate, enabling long-term sequestration. A significant challenge in the application of HBCS is the identification of an environmental-friendly promoter to enhance or tune CO2 hydrate kinetics, which is intrinsically sluggish. In addition, the promoter identified should be effective in all CO2 sequestration conditions, covering CO2 injection as gas or liquid. In this study, we introduced sodium lignosulfonate (SL), a by-product from the papermaking industry, as an eco-friendly kinetic promoter for CO2 hydrate formation. The impact of SL (0–3.0 wt.%) on the kinetics of CO2 hydrate formation from gaseous and liquid CO2 was systematically investigated. CO2 hydrate morphology images were acquired for both gaseous and liquid CO2 in the presence of SL for the explanation of the observed promotion effect. The promotion effect of SL on CO2 hydrate formation is optimal at 1.0 wt.% with induction time reduced to 5.3 min and 21.1 min for gaseous and liquid CO2, respectively. Moreover, CO2 storage capacity increases by around two times at 1.0 wt.% SL, reaching 85.1 v/v and 57.1 v/v for gaseous and liquid CO2, respectively. The applicability of SL as an effective kinetic promoter for both gaseous and liquid CO2 was first demonstrated. A mechanism explaining how SL promotes CO2 hydrate formation was formulated with additional nucleation sites by SL micelles and the extended contact surface offered by generated gas bubbles or liquid droplets with SL. The study demonstrates that SL as an effective promoter for CO2 hydrate kinetics is possible for adoption in large-scale HBCS projects both nearshore and offshore.

将木质素磺酸钠作为针对气态和液态二氧化碳的水合物进行二氧化碳封存的有效促进剂
以水合物为基础的二氧化碳封存(HBCS)是以固体水合物形式封存二氧化碳以降低大气中二氧化碳浓度的一种前景广阔的解决方案。海洋海底高压低温的自然条件为二氧化碳水合物提供了理想的储层,可实现长期封存。HBCS 应用中的一个重大挑战是找到一种环境友好型促进剂,以增强或调整二氧化碳水合物动力学,因为二氧化碳水合物动力学本质上是缓慢的。此外,确定的促进剂应在所有二氧化碳封存条件下都有效,包括以气体或液体形式注入二氧化碳。在本研究中,我们引入了造纸工业的副产品木质素磺酸钠(SL)作为二氧化碳水合物形成的环保型动力学促进剂。我们系统地研究了 SL(0-3.0 wt.%)对气态和液态 CO2 形成 CO2 水合物动力学的影响。为了解释所观察到的促进作用,在 SL 存在的情况下采集了气态和液态 CO2 的 CO2 水合物形态图像。SL 对 CO2 水合物形成的促进作用在 1.0 wt.% 时达到最佳,气态 CO2 和液态 CO2 的诱导时间分别缩短至 5.3 分钟和 21.1 分钟。此外,在 1.0 wt.% SL 条件下,二氧化碳的储存能力提高了约两倍,气态和液态二氧化碳的储存能力分别达到 85.1 v/v 和 57.1 v/v。SL 作为一种有效的动力学促进剂对气态和液态 CO2 的适用性首次得到了证实。通过 SL 胶束的额外成核位点以及生成的气泡或液滴与 SL 的扩展接触面,提出了 SL 如何促进二氧化碳水合物形成的机理。研究表明,SL 作为二氧化碳水合物动力学的有效促进剂,可用于近岸和离岸的大型 HBCS 项目。
