Nowadays in many developed countries the programs on power systems transfer on new more available biogen fuel that can help to solve some ecological and technological problems have been developed. Peat - mineral compositions can become such fuel. Physical - chemical study of composite granulated fuel on the basis of peat has been carried out. The granulation of organic mineral mixture by the method of palletizing allows to proportion exactly the initial components and to obtain solid bio-fuel with good technological characteristics (heat of combustion, humidity, strength, loosens and others). The aim of the investigations is to study peat low - temperature pyrolysis in the presence of catalytic systems on the basis of natural alumosilicate materials and synthetic zeolites. In the present paper the following problems have been solved: to study the influence of temperature, nature and the catalyst amount on composition and calorific value of combustible gas mixture obtained and to choose optimal conditions of this process. The study of peat low-temperature pyrolysis has been carried out in the presence of the catalysts - natural and synthetic materials with concentration 1, 2, 3, 4, 5 and 10 mass % at a temperature range of 350-480°C. The best results have been observed at 2% alumosilicate minerals content of peat mass at a temperature of 480°C. Under such conditions of the experiment hydrocarbon yield as well as the heat of combustion of the pyrolysis gas obtained has been much higher than those of non-catalytic process. The value of activation energy for the catalytic process of peat pyrolysis has been approximately 2 times less than for the non-catalytic one. As the result of the experiments carried out the application of natural and synthetic zeolite catalysts in peat catalytic pyrolysis was revealed to increase gaseous hydrocarbons yield by 2,1 - 2,5 times in case of natural catalysts and approximately by 4 times incase of synthetic ones. The heat of combustion has increased by 1,5 - 4 times on different catalysts.
