At the operating conditions adopted, the tests of stem/oxygen gasification of almond shells provided a gas yield
of 1.2 Nm3
dry/kgdaf with a dry composition of: 28-30%v H2, 24-26 %v CO, 34-36 %v CO2, 6-8 %v CH4 and 4 %v
light hydrocarbons (i.e. C2+). For this produced gas it was then evaluated a corresponding calorific heating value in
the range 10-12 MJ/Nm3
dry. At the exit of the reactor, the gas showed a water content of about 400 g/Nm3
dry and a
total chromatographic tar content of 10 g/Nm3
dry. Aromatic compounds belonging to many classes were present,
from single ring compounds, such as toluene and phenol, up to multi condensed rings such as benzo
