dehumidifiers; 4-condensate trap; 5-cooling mixture; 6-
thermometers; 7-gas trap; 8-gas watch; 9-clamps; 10-
flow indicator; 11-gas meter
The selection rate of 18-25l / min, the duration 
of the selection of 1.0-1.5 hours. During this time, 
1000-1500 l of pyrogas is passed through a dry gas 
meter and 300-450 g of liquid pyrolysis products are 
obtained, which is sufficient to calculate the yields of 
pyrolysis products with satisfactory accuracy. 
The analysis of gaseous (with the determination of 
hydrocarbons up to C5) and liquid parts of the sample, 
along with the analysis of the feedstock, is carried out 
in laboratory conditions by a chromatographic method. 
The density and fractional composition (Angler 
distillation) of raw materials and liquid products are 
also determined. 
The analysis of the group composition of raw 
materials is carried out by a chromatographic method, 
as a rule, on three instruments: on a column with a 
stationary phase [tris (2-cyanoethoxy) propane], the 
content of aromatic hydrocarbons is determined, with 
13X zeolites, the content of C5-C11 cyclanes, on a 
capillary column with OV siloxane The -1-content of n-
alkanes and, in difference, calculate the content of 
alkanes of isomeric structure.
