Formaldehyde catalyst contrast experiment self-balanced reaction equipment

Abstract

The invention belongs to the technical field of catalyst contrast experiment, and provides a formaldehyde catalyst contrast experiment self-balanced reaction equipment. The formaldehyde catalyst contrast experiment self-balanced reaction equipment comprises a reaction unit and a heat conduction oil unit which are communicated with each other; the reaction unit comprises a reactor provides with a shell side; the heat conduction oil unit comprises a heat conduction oil tank, a heat conduction oil pump, a heat conduction oil electric heater, and a heat conduction oil cooler; the heat conduction oil tank is communicated with the lower part of the shell side of the reactor through the heat conduction oil pump and the heat conduction oil electric heater; the upper part of the shell side of the reactor is communicated with the heat conduction oil cooler; the heat conduction oil cooler is communicated with the heat conduction oil tank; the bottom of the reactor is provided with a heat conduction oil heating coil pipe. The formaldehyde catalyst contrast experiment self-balanced reaction equipment is mainly suitable for contrast experiment of formaldehyde catalysts, and is also suitable forcontrast experiment of a plurality of tubular reaction catalysts; and self-balance of high, middle, and low exothermic reaction is realized.

Description

technical field [0001] The invention relates to the technical field of catalyst comparison experiments, in particular to self-balanced reaction equipment for formaldehyde catalyst comparison experiments. Background technique [0002] At present, there are many kinds of formaldehyde catalysts, but there are not many studies on the ratio and filling scheme of the catalysts. Most of the heat transfer in the shell and tube reactor is realized by the principle of thermosiphon, but for the reaction equipment of the catalyst comparison experimental device, it is not only necessary to compare the two catalysts under the same conditions, but also to realize the heat release of different catalysts. The heat removed from the environment can continuously increase and decrease the heat and temperature removed by the reaction according to the needs of the reaction process. The service activity and service life of the catalyst not only depend on the active components of the catalyst, but ...
