Abstract
The effect of pulsed laser radiation (1064 nm, 120 μs, 10 Hz, 1.5 J/cm2) on coal samples in argon is under study. Mass spectrometry is used to analyze the gaseous products of coal pyrolysis. The dependences of the composition of gaseous pyrolysis products of coal samples and the proportion of reacted samples on their technical and genetic characteristics are established. Data on the yield of combustible gases per unit mass of reacted coal samples were obtained.
