Problems solved by technology

But there is a common problem - the test efficiency is too low: the pretreatment (purging) of the catalyst sample and the baseline of the instrument cannot be carried out simultaneously; each catalyst sample needs to be re-baselined before testing; Slow, which greatly reduces the efficiency of scientific researchers

Abstract

The invention provides a program heating analysis equipment and a method for testing property of its catalyst, which can be used for testing program heating reduction, program heating oxidation and temperature programmed desorption. The program heating analysis equipment comprises a first air supply pipeline, a second air supply pipeline, a pressure-reducing valve, a pressure-stabilizing valve, a constant flow valve, a compression gauge, a mass flowmenter, a non return valve, a six-way valve, a U-shaped reaction tube, heating furnaces, a thermocouple, a temperature controller, a thermal conductance pool detector, a data processing work station and a computer. The design of the six-way valve can conveniently realize the switching of two ways of gas, a purpose of simultaneous operation of a pretreatment process of a catalyst sample and a base line recording process of the equipment can be reached, time is greatly saved, and testing efficiency is increased; design of three heating furnaces is convenient for replacing the high temperature heating furnace, waiting time for cooling the heating furnace is saved, and testing efficiency is increased.

Description

technical field [0001] The invention belongs to the technical field of gas-solid phase catalysis, and in particular relates to a temperature-programmed analysis device and a method for testing properties of catalysts thereof, which are mainly used for testing the oxidation-reduction performance and surface acidity and alkalinity of catalyst samples. Background technique [0002] As we all know, more than 80% of the chemical industry involves catalytic processes, and the level of development of catalytic technology reflects the degree of development of a country. At the same time, catalytic technology also plays a pivotal role in the fields of environmental pollution control, new energy development and new material development. According to the similarities and differences of physical states, catalytic reactions can be divided into: homogeneous catalysis and heterogeneous catalysis. Among them, heterogeneous catalysis has become a research hotspot due to its advantages such ...
