Abstract

The invention discloses a waste catalyst treating device and technology thereof. The device mainly comprises a waste catalyst storing tank, a cracker, a cooler, a buffering tank and an incineration system, wherein the cracker is of a kettle type structure and comprises stirrers, ignitors, observing holes, waste catalyst adding ports, air adding ports, cracking agent adding ports, a filtering device, a cracking gas outlet and a refractory material; and the stirrers, the ignitors, the observing holes, the waste catalyst adding ports, the air adding ports and the cracking agent adding ports are symmetrically arranged. The waste catalyst treating technology mainly comprises the steps of cracking waste catalyst which is tributylamine into combustible gas under the effect of a cracking agent; filtering and cooling the combustible gas to reach a certain temperature; buffering through the buffering tank; and then continuously stably supplying fuel to the incineration system.

Description

technical field [0001] The invention relates to the technical field of waste catalyst disposal, in particular to a waste catalyst tri-n-butylamine disposal device and a process thereof. Background technique [0002] Tri-n-butylamine, a colorless or light yellow liquid under normal pressure, has a special smell, is weakly alkaline, easily soluble in ethanol, ether, etc., slightly soluble in water, highly toxic chemical. In the process of producing pentafluoroethane (R125) with tetrafluoroethylene and anhydrous hydrogen fluoride, it is necessary to use tri-n-butylamine as a catalyst for catalytic reaction. During the recycling process of the catalyst, as the number of reactions increases, the catalyst reactivity decreases and loses The catalytically active catalyst needs to be replaced. The spent catalyst cannot be discarded directly or disposed of casually due to its high toxicity, and the spent catalyst contains F elements. The pressure on the harmless disposal of the spent ...
