Study on SO42−/ZrO2-MoO3 in the integrative transformation of cottonseed oil deodorizing distillate

Synthesis and E-metric Studies of an Economically Viable Heterogeneous Acid Catalyst for Production and Upscaling of Solketal

“…To address the above-mentioned limitation, various M x O y (including ZrO 2 and Al 2 O 3 ) have been studied in the synthesis of composite solid acid SO 4 2– /TiO 2 -M x O y catalysts. CoAl 2 O 4 metal oxide was synthesized and incorporated with titanium, which improved catalytic activity and structural stability in solketal synthesis. − It is found that CoAl 2 O 4 oxide acts as an M x O y to synthesize the SO 4 2– /TiO 2 -M x O y type composite, which improves the catalytic activity, thermal stability, and acidic properties. No reports have been found on the efficient synthesis of the SO 4 2– /CoAl 2 O 4 -TiO 2 solid acid catalyst and its catalytic application in glycerol acetalization.…”

Enhanced catalytic activity and stability of SO2-4/ZrO2 solid acid catalyst combined with carbon nanotubes

“…Some of the solid acid catalysts have been investigated as potential replacements for mineral acids; in the reactions of ketalization SO 2 À 4 =ZrO 2 has been extensively investigated. For example, SO 2 À 4 =ZrO 2 exhibits a highly active and versatile solid acid catalyst in many reactions [4][5][6][7][8][9][10][11][12][13][14][15][16][17]. However, catalytic activities of these materials are limited because of low surface area and stability.…”
