Kinetics of benzene alkylation with 1-dodecene over a supported tungstophosphoric acid catalyst

The prepared catalyst of tungstophosphoric acid supported on SiO 2 has shown high activity, good selectivity of producing linear alkylbenzene (LAB) and 2-phenyl isomer and sufficient catalytic stability. Kinetics of benzene alkylation with 1-dodecene over this catalyst was investigated in a fixed-be...

More Information
Summary:The prepared catalyst of tungstophosphoric acid supported on SiO 2 has shown high activity, good selectivity of producing linear alkylbenzene (LAB) and 2-phenyl isomer and sufficient catalytic stability. Kinetics of benzene alkylation with 1-dodecene over this catalyst was investigated in a fixed-bed reactor after eliminating the influence of internal and external transport. Rate models of formation of different isomers of LAB were derived based on some simplifying assumptions. Kinetic parameters were determined.
