In order to meet the needs of methylal synthetic fluidized catalytic distillation column, a rapid macro-kinetic determination method of raw particle catalyst - continuous temperature measurement and its device was established. The macro-dynamic of the synthesis reaction of methylal on different particle size catalysts Using the approximate analytical solution of the effective factor of the second-stage reversible reactive spherical isothermal catalyst, the effective diffusion coefficient was estimated.
