7. Syngas Conditioning (Catalyst, Process: Sulfur and Tar Cl, F)

Parvin Kiani, Maryam Meshksar, Mohammad-Amin Makarem, and Mohammad-Reza Rahimpour
- Abstract
Synthesis gas (usually referred to as syngas) is a gaseous energy carrier that generally consists of H2 and CO, which is produced widely via natural gas or biomass reforming and gasification. Based on the feedstock used and also the condition of the gasification method, the syngas produced contains some impurities, including particulate matter, acidic gases (CO2, H2S, etc.), nitrogen-containing compounds (N2, NH3, HCN), halogen-containing derivatives (HCl, HBr, HF), tar compounds, etc. These should be eliminated stepwise, in order to avoid catalyst poisoning or reducing subsequent conversion processes that use syngas as a feedstock. This chapter introduces different syngas impurities and the associated elimination methods, especially those used for removing sulfur-containing and tar compounds that are based on absorption technology for sulfur compounds or physical and thermal methods used for the removal of tar.

A new Quantitative Structure-Activity Relationship model is introduced for reliable prediction of the toxicity of organic aromatic compounds based on the logarithm of 50 % growth inhibitory concentration of Tetrahymena pyriformis (log(IGC50−1)), which have extensive use in ecotoxicology and environmental safety applications. The largest experimental data set of log(IGC50−1) for 892 organic aromatic compounds is used to derive and test the new model. A core correlation based on additive variables is introduced by the number of nitro groups, carbon and halogen atoms as well as some specific polar groups and molecular weight. An improved correlation based on two non-additive correcting functions is developed for the increment of the reliability of the core correlation. The reliability of the improved correlation is tested and compared with two of the best available methods, which require complex descriptors. The predicted results for 661 and 231 of training and test sets have been confirmed by internal and external validations. The values of correlation coefficient (R2), mean error (ME), root mean squared error (RMSE), and maximum of errors (Max Error) for 661/231 of training/test aromatic compounds are 0.8442/0.7771, 0.0000/0.0149, 0.3166/0.3603, and 0.9732/0.9825, respectively, which are good results as compared to extra complex models with lower reported data. Various statistical parameters confirm the goodness-of-fit, high reliability, precision, and accuracy of the novel model.

In the current project, V2O5 extraction from fuel fly ash was carried out, and the advanced extraction method was investigated. This reduced the percentage of industrial fuel fly ash residue pollution in the environment. The project was done with two materials: V2O5 and fuel fly ash. The extraction method includes alkaline leaching, pH regulation, ammonium compounds addition, and calcination. The experiment was identified using V2O5 as the primary material. Under the optimum amounts, the extraction efficiencies of V2O5 reached 92.9%, 92.9%, 99.6%. moreover, V2O5 eliminated over 90% of fuel fly ash. The obtained products were characterized using X-ray powder diffraction (XRD), Alkaline fusion-ICPMMS, Ultraviolet-visible (UV-Vis), and Fourier Transform infrared (FT-IR).

In this work, lanthanum-combined silica mesoporous (SBA-16) supported Ni-based catalysts are synthesized and examined for synthesis gas (syngas) production in the dry methane reforming (DMR) process. The pH-adjusted hydrothermal technique has been used to modify the mesoporous silica-based support, which has been then impregnated by Ni particles. The pH value had a substantial impact on creating well-ordered mesostructures and lanthanum ion replacement inside the SBA-16 structure. Therefore, at the ideal pH of 3.80, a zeolite-like mesostructure of Si-La has been produced. Thus, La2O3 species have been inserted in the SBA-16 structure, favoring a larger dispersion of impregnated Ni particles of lower dimensions. In addition to the pH modification during the synthesis step, the effects of lanthanum loading and Ni weight percentage variation on the catalytic performance as well as the physicochemical analyses of the catalysts have been also explored. The calcined catalysts have been tested in the DMR process in the temperature range of 600-750 oC. Furthermore, the coke resistance, activity, and structural changes of optimal catalysts have been studied over 11 h. The results showed that the 15Ni/40La- SBA16(3.80) catalyst performs the best structural characteristics and catalytic activity.
