This paper describes experimental investigation of corn stalk pyrolysis. The
mass of the sample (corn stalk) inside a pyrolytic reactor was 10 g with
particle diameter of 5-10 mm. The sample in the reactor was heated in the
temperature range of 24-650?C and the gas components generated during corn
stalk pyrolysis were measured using gas analyzer G750 POLYTECTOR II. The
sample mass before, during and after pyrolysis process was determined by
using METTLER P1000 digital scale. Experimental results of the corn stalk
pyrolysis indicate that as the temperature in the reactor increases from
300-650?C, the pyrolytic gas yield increases from 60-72%, while the char
(coke) yield decreases from 40-28%. In the temperature range mentioned, the
CO2 volume fraction in pyrolytic gas decreases, while the volume fraction of
methane increases up to 39.5% followed with a constant decrease in the volume
fraction of oxygen. The results obtained can represent starting basis for
determining material and heat balance of pyrolysis process as well as corn
stalk pyrolysis equipment.
