gasification
The effect of gasifier internal diameter and biomass type (molar
ratio H/C) on the gasification process was studied by means of a
multifactorial 22 experimental design. The factors and their respective
levels, as well as, the test codes are shown in Table 4. Table 1
shows the composition and heating values of the test fuels: pine
bark (H/C = 1.19) and sewage sludge (H/C = 1.63).
