Multi-example high-temperature rotating and roasting device

Abstract

The invention relates to a multi-sample high-temperature rotary roasting device which comprises a roasting furnace, a sample cup, a rotary driver, a temperature controller, and the like. The invention can simultaneously carry out the water heat treatment (aging) of 2 to 24 samples, improve the test efficiency, eliminate the difference of aging conditions among different samples at the same time, and improve the quality of aging tests. The aging condition is from 300 DEG C to 850 DEG C, the partial pressure of water vapor is from 0.1 MPa to 0.5 MPa (absolute), and the aging time is from 1 hour to 30 hours.

Description

technical field [0001] The invention relates to a test device, in particular to a multi-sample high-temperature rotary roasting device, which is used for heat treatment, hydrothermal treatment, hydrothermal aging, hydrothermal superstability and other deactivation processes of samples such as molecular sieves, catalysts and adsorbents. Background technique [0002] Heat treatment or hydrothermal treatment is an important method for preparing molecular sieves, adsorbents and catalysts. The most conventional heat treatment device is a muffle furnace. However, those skilled in the industry know that there are problems with the temperature control accuracy of the muffle furnace and the temperature uniformity during multi-sample processing. In the process of industrial use of general molecular sieves or catalysts, the activity decays slowly, and the laboratory can only use more severe conditions to simulate the decay of industrial processes, so as to develop better catalysts faste...

Problems solved by technology

This device has played an important role in improving the efficiency of catalyst evaluation tests and saving energy and manpower, but its disadvantage is that hanging baskets are arranged in series in hanging baskets, and the aging severity of the upper and lower samples is different, and the exhaust gas of the upper sample affects the lower sample. , and issues such as steam channeling
