“…It is used for simulation to study the effect of parameters such as types of absorbing agents, concentration of solutions and liquid flow rate on CO2 and H2S removal from gasification. The simulation results are based on the data of experimental work from Hanaoka et al 5) at 0.9 MPa absolute and 25 °C and concentration of inlet acid gases.…”

Due to the high energy consumption and decreasing oil supply, the alternative energy sources such as biomass and agricultural waste can be considered as the main sources of energy in the future. Currently, one of the technologies to convert such biomass to more valuable products is biomass-to-liquid process. However, acid gases like CO 2 and H2S are produced as intermediates causing the decrease in product heating values, operational problems, corrosion, and environmental concern. Therefore, the objective of this work is to simulate the absorption process of acid-gas cleaning by using various solutions at different operating conditions in order to meet the requirement. The results show that MDEA has higher performance to remove both gases compared to other chemicals. Furthermore, at 0.9 MPa and 25 °C, the treated gas provides 3.19 vol% CO 2 and 27.7 ppb of H2S for MEA, 2.13 % CO2 and 0.02 ppb of H2S for MDEA and 7.45 % CO2 and 1.12*10 -6 ppb of H2S for Selexol. Moreover, the liquid flow rate, solution concentration and effects of temperature and pressure are also investigated for the optimal design of the absorption column.

“…Figure 5 shows a schematic diagram of the bench-scale BTL plant used to capture impurities and the location of the sampling ports for collecting gas, tar, and particles. The apparatus contained a down-draft fixed-bed gasifier (capacity: 1.44 t day −1 on a wet basis) [38], a cyclone, activated filters A and B, a scrubber, and a roots blower. Particulates containing inorganic matter, unreacted char, and relatively large particles were removed by the cyclone.…”

This study proposes a gas-cleaning process for the simultaneous removal of sulfur compounds, tar, and particles from biomass-gasified gas using Fe-supported activated carbon and a water-gas shift reaction. On a laboratory scale, the simultaneous removal of H 2 S and COS was performed under a mixture of gases (H 2 /CO/CO 2 /CH 4 /C 2 H 4 /N 2 /H 2 S/ COS/steam). The reactions such as COS + H 2 → H 2 S + CO and COS + H 2 O → H 2 S + CO 2 and the water-gas shift reaction were promoted on the Fe-supported activated carbon. The adsorption capacity with steam was higher than that without steam. On a bench scale, the removal of impurities from a gas derived from biomass gasification was investigated using two activated filters packed with Fe-supported activated carbon. H 2 S and COS, three-and four-ring polycyclic aromatic hydrocarbons (PAHs), and particles were removed and a water-gas shift reaction was promoted through the first filter at 320-350 °C. The concentrations of H 2 S and COS decreased to less than 0.1 ppmv. Particles and the one-and two-ring PAHs, except for benzene, were then removed through the second filter at 60-170 °C. The concentration of tar and particles decreased from 2428 to 102 mg Nm and from 2244 to 181 mg Nm −3 , respectively.

Lignin in wood and organic wastes can be converted to motor fuels by a biomass-to-liquid (BTL) process using a syngas platform [2,3]. Vegetable oils can be converted to fatty acid methyl esters (FAME, known as biodiesel) by transesterification with methanol [4].…”
