Modeling and optimization of the catalytic isomerization of the pentane-hexane fraction with maximization of individual high-octane components yield

A mathematical model of catalyst combination design and temperature control in the preparation of C4 olefins through ethanol coupling

“…The optimization model was established using eqn (6) and was constructed as follows: 35 max y I = 77.1798 − 129.936 × T − 2.3408 × x 2 + 54.831 × T 2 − 0.7725 × T × x 1 + 41.1626 × T × x 2 …”
