The influence of temperature on the speed of reduction of TIN oxide with argon- hydrogen mixture
Abstract
Recently, the usage of hydrogen in the processes of metal extraction has been a very important challenge to metallurgic industry. Replacing conventional reductor, taking into consideration CO2 emission restrictions will enable maintaining and developing this branch of industry. The results of the research on tin oxide SnO reduction using hydrogen given as a mixture Ar – 5 % vol.H2 in temperature range 773 – 873 K. are shown in this article. The tests were conducted using thermogravimetric method. It is demonstrated that with the rise of a temperature in the analyzed range the speed of reaction rises as well and the obtained degree of reduction varies from 40 to 99,5 %. Stabilization the weight change in the tested sample thermogravimetric (TG) was reached after from 25 min for 773 K to 15 min for temperature 873 K.
