Abstract:
Syngas has been utilized in the production of chemicals and fuels, as well as in the creation of electricity. Feedstock impurities, such as nitrogen, sulfur, chlorine, and ash, in syngas have a negative impact on downstream processes. Fischer–Tropsch synthesis is a process that relies heavily on temperature to increase the production of liquid fuels (FTS). In this study, waste biomass converted into activated carbon and then a carbon-supported iron-based catalyst was prepared. The catalyst at 200 °C and 350 °C was used to investigate the influence of temperature on the subsequent application of syngas to liquid fuels. Potassium (K) was used as a structural promoter in the Fe-C catalyst to boost catalyst activity and structural stability (Fe-C-K). Low temperatures (200 °C) cause 60% and 80% of diesel generation, respectively, without and with potassium promoter. At high temperatures (350 °C), the amount of gasoline produced is 36% without potassium promoter, and 72% with promoter. Iron carbon-supported catalysts with potassium promoter increase gasoline conversion from 36.4% (Fe-C) to 72.5% (Fe-C-K), and diesel conversion from 60.8% (Fe-C) to 80.0% (Fe-C-K). As seen by SEM pictures, iron particles with potassium promoter were found to be equally distributed on the surface of activated carbon.Keywords:

Catalytic conversion of biomass-derived syngas (bio-syngas) into gasoline range hydrocarbons has been regarded as one of potential routes to utilize biomass. In this route, biomass is firstly converted into bio-syngas through biomass gasification. Then bio-syngas is catalytically converted into transportation fuels or chemicals. In this paper, catalytic synthesis of gasoline range hydrocarbons by using model syngas similar to bio-syngas has been carried out over Mo/HZSM-5 catalysts. Different system temperatures were adopted in the experiments to figure out the effects of reaction parameters. The products were analyzed by GC and GC-MS. The catalysts were characterized by SEM-EDS and TEM. The results showed that Mo/HZSM-5 was active in model bio-syngas.

Synthesis gas (syngas) refers to a mixture primarily of hydrogen (H 2 ) and carbon monoxide (CO) which may also contain significant but lower concentrations of methane (CH 4 ) and carbon dioxide (CO 2 ) as well as smaller amounts of impurities such as chlorides, sulphur compounds, and heavier hydrocarbons. Available syngas dispersion study found in literatures mostly focused on pure gas dispersion specifically H 2 compared to the syngas mixture. It has been reported in most literatures that available commercial tools tend to give an overestimated results for these types of gas since it is more suitable for dense gas rather than the light gas. Therefore, the current study aim to investigate potential dispersion and evaluate the flammability of syngas release from biomass processes using CFD-FLUENT. Results of the mixture simulation is compared with the results obtain from simulation of pure H 2 release. When all components in syngas were release together, competition to gain oxygen increased resulting in lesser mixing of syngas-oxygen and increasing the concentration of the syngas mixture. As a result, H 2 in syngas concentration is higher compared to pure H 2 when accidental release from biomass process.

Application of syngas from RPF(Refused Plastic Fuel) on a power generation engine is investigated in a pilot scale test rig. The syngas was generated from a stoker type pyrolysis-gasification system of multi-staged waste pyrolysis process and experiments were conducted on a 20㎾e commercial syngas power generation engine. The syngas is mainly composed of hydrogen, carbon monoxide, carbon dioxide and methane and the performance of the engine was tested with various syngas composition. Electric power output and exhaust gas emissions are monitored for syngas and compared with the result of LNG case. This is a preliminary result of the application of waste syngas on a power generation engine.

The catalytic partial oxidation of methane to syngas (CO+H2) has been simulated thermodynamically with the advanced process simulator PRO/Ⅱ. The influences of temperature,pressure,CH4/O2 ratio and steam addition in feed gas on the conversion of CH4 selectively to syngas and heat duty required were investigated, and their effects on carbon formation were also discussed. The simulation results were in good agreement with the literature data taken from a spouted bed reactor.
