Comparison of coal reactivityduring conversion into different oxidizing medium

Acoal conversion process of different coal samples into three different types of oxidizing medium (argon, air and steam) were studied by means of thermogravimetry. Two coal types with different metamorphism degree (lignite and bituminous coal) were used. The experimental procedure was carried out in non-isothermal conditions in temperature range from 373 K to 1273 K with 20 K/min heating rate. Purge gas consisted of argon and oxidizer with volumetric ratio 1:24 and had 250 ml/min flow rate.The ignition and burnout indexes were calculated to evaluate sample reactivity at different oxidizing mediums. The highest reactivity coefficient values in same atmosphere were obtained for lignite. It was caused by higher particle special surface area and volatile matter content.

Analytical study of the impact of implementation of Federal target programs involving students enrolled in the graduate program for the purpose of obtaining practical skills, identify and develop organizational skills, to increase motivation for learning. Training of students in the program graduate with their attraction to the implementation of research projects led to the development of a number of competences and higher achievement. The average score increased from 4,23 (2014) to 4,55 (2015). Publication activity has increased by 64% and the number of conferences with the participation of students has increased by 75%. The increase in these indicators is due to the large number of the experiments and perform analytical reviews. The main factor determining the high level of motivation masters at work is additional financial support from the funds of their programs.
