高压变压吸附模拟仪可用于尾气固着连续 双床变压吸附生产负排放生物甲烷

在沼气提纯和随后的封存过程中选择性去除CO2可以将产生的生物甲烷从碳中性能源转变为碳负能源。我们可以将这种技术视为具有碳捕获和存储（BECCS）的生物能源，即负排放技术（NET）。在这项研究中，具有高于大气压的实际工作能力和循环性能的多孔聚合物珠（PPB）被开发用于通过变压吸附（PSA）进行沼气提质，而无需真空。在0-70°C的温度范围和0-10 bar的压力范围内测量PPB的CO2和CH4平衡等温线。在2 bar和10 bar下测量40:60（vol％）CO2 / CH4气体混合物的动态穿透曲线。这些等温线和突破曲线被用作动态PSA模拟模型的输入，以预测双床PSA沼气升级过程的性能。该模型表明，可以产生CH4回收率为91％的沼气，并且尾气中的CO2纯度可达90％以上，适合地质储藏，可分离。

    需要强调的是，与当前最先进的PSA装置不同，拟议的使用PPB的工艺可以以最低的能耗升级沼气以再生吸附剂。拟议的选择性尾气分离方案可用于生产碳负生物沼气 。

General Description

L&C’s PSA-1000 Testing Systems are customizable to broad ranges of gas flow rate and adsorbate bed size to meet your specific requirements, come with expert installation/training support .

These R&D Testing Systems offer L&C’s unique hardware configuration and proprietary software which simplify all levels of gas separation evaluations. Automated testing is provided over wide ranges of gas flow, temperature, pressure and vacuum, enabling the researcher to effectively and efficiently explore the complex “experimental matrix” of PSA and VSA studies.

The PSA System handles materials evaluations for activated carbons, zeolites, metal organic frameworks (MOFs), molecular sieve materials and more… and is especially effective for mixed-bed testing applications and the study of adsorbate poisoning and critical time-cycling.

System design and materials of construction permit the evaluation of all types of gases and adsorbate materials for chemical, petrochemical, gas purification and energy-related applications in academic, industrial and government R&D laboratory settings.
