Exceptional HCl removal from Hydrogen gas by Reactive Adsorption on a Metal-Organic Framework
Abstract
Small quantities of hydrogen chloride (HCl) are found in the hydrogen gas, obtained via traditional methods. Besides the contamination of the product stream, HCl causes corrosion, fouling and equipment damage leading to potentially serious safety and environmental issues. Thus, removal of HCl from the hydrogen gas is of great importance for the chemical industry. Here, we present a study on the removal of hydrogen chloride from hydrogen gas via adsorption on different adsorbents including zeolites, activated carbon and metal-organic frameworks (MOFs). The HCl removal performance of these adsorbents was studied by breakthrough experimentation with fixed-bed (dynamic) under high gas velocities (> 0.3 m/s), at high pressure (30 bar) and at room temperature, and with low HCl concentrations (< 200 ppm). The study revealed a MOF with an exceptional HCl adsorption capacity of 1.02 g/g, outperforming by far all traditional materials and other metal-organic framework previously tested. The characterization performed, via SEM-EDX, XRD and TGA, before and after the HCl contact unveiled the reaction nature of the adsorption mechanism, where the MOF undergoes a complete re-crystallization into a salt complex.
