Scientists of the Kuzbass State Technical University (a member of the Kuzbass REC) have developed a technology for processing coal waste into a safe gas similar in composition to natural gas. This technology reduces emissions of harmful substances by 2.5-3 times.
As an innovative development, a technological solution was proposed for the processing of coal waste using a binder in the form of dewatered excess activated sludge in order to obtain gaseous fuel. The characteristics of the environmental hazard from the use of the obtained fuel in comparison with the traditional combustion of fossil fuels in terms of the emission of harmful substances turned out to be 2.5-3 times lower.
During the study, scientists formed fuel pellets, dried them to determine the abrasion strength. Further, in the process of pyrolysis (thermal decomposition), a gas was obtained.
The studies carried out have shown that the composition of the produced gas is equivalent to that of natural gas. Thus, in the future, it can be used as a gaseous energy carrier in apartment buildings and private residential buildings for cooking, heating and heating water, as well as fuel for cars and boiler houses.
On the basis of the developed technology, it is planned to create installations that will be designed according to the requirements of a specific customer, taking into account the specifics of the generated waste planned for processing. The estimated cost of small-sized plants will vary within 5-6.5 million rubles, depending on the type of raw materials, processing volumes and operating conditions.
