Abstract：The support vector machine gasification model was established based on the vinegar residue gasification experiment. Gasification temperature,
vinegar water content and mass ratio of biomass to water vapor were input into the model with the main gas group of H2, CH4, CO and CO2 as output to realize
the output process from input. To test the data from vinegar residue gasification experiment, 3 sets of data were selected as model test group with the
remaining data as training sample. The vinegar residue gasification model was established by Matlab. The best penalty parameter C was 9.551 2 with optimal
width parameter sigma of 92.723. After the completion of model establishment, three groups of data were picked randomly and verified, and the prediction of
gas composition was compared with the experimental data. The results show that the average errors of H2，CO，CH4 and CO2 are respectively 2.87%， 3.28%，
2.66% and 3.04%.
