【Abstract】 The kinetics of isomerisation of 1-butene over Lu2O3/SiO2 catalyst has beeninvestigated by the flow-recirculation glass reactor. The heats of adsorption for 1-butene,2-butene and water were deteched by the pulse method. The kinetics of isomerizationof 1-butene obeys the L-H mechaniasm Kinetic equation. We observed that L-H kineticequation with two parameters is the good-conditioned equation. The L-H kinetic equation with more than three paramters is a ill-conditioned equation. The condition numberof normal equation increases with the increase of paramter numbers for kinetic equation.In addition, we observed that the condition number is not less than the square of ratio oflong to short in column vector for the coefficient matrix of contradiction equation.更多还原
