Self-Regenerative Ni-Doped Catio3/Cao For Co2 Capture And Utilization

Patent Status

Patent Pending

Full Description

Background

Integrated CO₂ capture and dry reforming of methane (ICCDRM) is a process that tackles two important greenhouse gases - CO₂ and methane (CH₄) - transforming them into useful syngas. Nickel/Calcium Oxide (Ni/CaO) based dual functional materials (DFM) are widely evaluated for integrated CO₂ capture and utilization (ICCU), especially in processes like dry reforming of methane (DRM), where CO₂ and CH₄ are converted into syngas. However, these conventional systems face significant challenges resulting in significant reduction in CO₂ capture and overall efficiency of ICCDRM, especially because of:

• Coke deposition on the Ni catalyst that reduces the efficacy of the catalyst; and,
• Stability of CaO resulting in pore collapse, surface area loss and/or agglomeration of Ni nanoparticles.

Invention

Prof. Abdul-Aziz and her team at UCR have developed a novel multifunctional material (MFM) designed to enhance the efficiency and stability of ICCDRM processes. The team successfully synthesized Ni-doped CaTiO₃/CaO nanocomposite, addressing key challenges associated with conventional Ni/CaO systems. The MFM effectively addresses the limitations of conventional systems, showcasing its potential for practical applications in carbon capture and utilization.
