Catalytic performance and mechanism of SO42−/ZrO2/SBA-15 catalyst for CO2 desorption in CO2-loaded monoethanolamine solution

Esterification of Succinic Acid Using Sulfated Zirconia Supported on SBA‐15

“…4 shows the FTIR spectra of the SBA‐15 siliceous support and SZ‐SBA‐15(10), SZ‐SBA‐15(20), and SZ‐SBA‐15(30) catalysts. All spectra show absorption bands due to the stretching and bending vibration modes of physisorbed water, at 3435 and 1638 cm −1 51, 52. The characteristic bands of the pure SBA‐15 support can also be distinguished at 1080, 800, and 470 cm −1 , associated with the asymmetric, symmetric, and bending stretching of Si‐O‐Si, respectively 53, 54.…”

“…The characteristic bands of the pure SBA‐15 support can also be distinguished at 1080, 800, and 470 cm −1 , associated with the asymmetric, symmetric, and bending stretching of Si‐O‐Si, respectively 53, 54. With increasing Zr load the band at 800 cm −1 becomes more intense 52. The band at 965 cm −1 can be attributed to the stretching vibration of the unbound silanol groups, which becomes unclear with increasing incorporation of zirconium 53.…”

A Review on Enhancing Solvent Regeneration in CO2 Absorption Process Using Nanoparticles

“…Another study reported on the amount of CO 2 released (mol) for each regeneration cycle and is an indicator regarding the particle's stability and ability to be recycled [106]. The changes in heat duty or energy consumption reported in each cycle can also be another indicator [107]. This is also closely related to the cyclic capacity of the material.…”

“…The results from comparing SAPO-34 zeolite and the blank amine solvent similar to previous studies, where the MCM-41 benefited over the blank test and SO 4 2− /TiO 2 but was poorer in comparison to the zeolite catalyst. Another material is SBA-15 that was compared with sulfated SBA-15 materials [107]. The CO 2 desorption performance of the non-optimized SBA-15 was reported to be lower than the blank MEA test and the employment of HZSM-5.…”
