摘要

Thermodynamic analysis of tri-reforming reactions to produce synthesis gas has been conducted by total Gibbs energy minimization to understand the effects of process variables, such as temperature (200-1000 ℃), pressure (1-20 atm), and inlet O_2/CH_4 (0-1.0), H_2O/CH_4 (0-3.0), and CO_2/CH_4 (0-3.0) mole ratios on the product distribution. The results reveal that high temperature and low pressure are favorable to achieve high H_2 production and CO_2 conversion. In addition, excessive additions of H_2O, O_2 and CO_2 bring about lower H_2 yield and CO_2 conversion, while low concentrations of H_2O, O_2, and CO_2 result in more intense carbon formation. To attain the maximum H_2 yield and high CO_2 conversion coupled with a desired synthesis gas (H_2/CO) ratio for the downstream methanol production and effective elimination of carbon formation, the corresponding optimum feed ratio in tri-reforming process is identified to be CH_4/CO_2/H_2O/O_2 = 1:0.291:0.576:0.088.
