Energy values of gaseous pyrolysis products of typical forest and aquatic plant biomass of Europe are investigated. Theoretical research of main characteristics of samples of typical plant biomass of Europe such as pine, thorn, microcystis, elodea is produced. Methodology and planning of experimental studies of process of pyrolysis of plant biomass are formulated. Experimental researches of composition of gas pyrolysis products of different types of plant biomass for different temperatures were carried according to laboratory conditions. Pyrolysis of plant biomass was carried out using a specially designed and manufactured pyrolysis plant the main part of which is a pyrolysis reactor. Installation made by our department is intended for slow pyrolysis. In research for determine presence and percentage of product yield qualitative and quantitative gas chromatography assays were used. The lower calorific value of gaseous pyrolysis products of samples of typical forest and aquatic plant biomass of Ukraine are calculated. As a result of calculations it was determined that during pyrolysis of aquatic plants and algae mixture of the obtained gases had the highest values of lower calorific value: 17,10-17,15 MJ/kg – for microcystis and 16,45-16,50 MJ/kg – for elodea. Gas obtained from pyrolysis of pine wood had the highest values of lower calorific value in the range of 13,8 to 13,85 MJ/kg. The lower calorific value of pyrogas obtained from thorn samples ranged from 12,6 MJ/kg to12,65 MJ/kg.
