“…In recent years, natural mineral materials as carriers or catalysts have been used in the research of tar catalytic conversion due to their unique advantages such as low cost and good catalytic performance [40][41][42]. Olivine is a natural iron-magnesium mineral ((Mg,Fe) 2 SiO 4 ) with low cost, high mechanical strength, and a certain catalytic activity, which is beneficial to be used as a catalytic bed material [40,[43][44][45][46]. It has been demonstrated that the catalytic activity of olivine can be attributed to its content of iron in different oxidation states (Fe 0 , Fe 2+ , and Fe 3+ ), dissociated from the olivine bulk to the surface during thermal treatment [19].…”

Bimetallic Cu/Ni/olivine catalysts with various Cu/Ni mass ratios were prepared for steam reforming of toluene as model tar compound. The effects of the Cu/Ni ratio, the reaction temperature, and the steam-to-carbon ratio (S/C) on the steam reforming of toluene were investigated in a fixed-bed reactor. Among the catalysts, olivine coated with 3 wt % CuO and 12 wt % NiO (Cu3/Ni12/O) achieved higher catalytic performance and structural stability due to the synergistic effect of Ni and Cu. The appropriate S/C and a higher temperature were beneficial to steam reforming of toluene. The catalytic performance was not only affected by the amount but also by the types of carbon deposition. Compared with the amorphous carbon, the larger amount of graphitic carbon formed on the catalyst surface was more likely to lead to a decreased catalytic performance.

“…Upgrading of gaseous products derived from biomass gasification (including enrichment, purification, and separation processes) to achieve hydrogen‐rich gas has faced many challenges. So that in recent years, many investigations have been done on gasification process parameters and other processes after that include gas cleaning, tar reforming, water‐gas shift (WGS) reaction, and separation process 11,22‐24 . Two main methods for tar removing from the gasification products are thermal cracking and catalytic reforming.…”

Summary A comprehensive model is developed to predict and optimize the hydrogen production via integrated configuration of steam gasification process of biomass and water‐gas shift reaction by taking advantage of the ASPEN plus software and sensitivity analysis techniques. The steam gasification process of three different generations of biomass, including corn cob as the first generation, wood residue and rice husk as second generation, and Spirulina algae as the third, are investigated and evaluated to achieve maximum hydrogen production. This model is successfully validated with experimental data reported in the literature about steam gasification of rice husk in the fluidized bed reactor. The impact of main operating parameters is considered in terms of products composition, hydrogen yield, CO conversion, H2/CO ratio in the gas products stream, and cold gas efficiency (CGE). The results indicated that the maximum hydrogen concentration is achieved at the highest steam to biomass (S/B) ratio in the gasifier and water‐gas shift (WGS) reactor and at the lowest WGS reaction temperature, whereas there is an optimum value about the gasification temperature. The highest CO conversion and H2/CO molar ratio belong to rice husk biomass at all considered range of temperature, whereas they are almost the same for wood residue and Spirulina. The predicted results confirmed that CGE of all feedstocks improves with increasing gasification temperatures and S/B ratio. The steam gasification performance of different feedstocks at 750°C is ranked as wood residue (83.56%) > spirulina (83.47%) > corn cob (74.94%) > rice husk (69.86%). The presented configuration can be applied as a novel approach for process evaluation and optimization through the downdraft biomass gasification integrated with water‐gas shift reaction to intensify the hydrogen production.

Oil palm empty fruit bunch (OPEFB is one of the enormous waste expected to become a renewable energy source. This study aimed to convert OPEFB into syngas through a gasification process using bentonite as a catalyst. The effects of temperature and product gas catalysts were investigated, and the efficiency of the gasification process was summarized. The process has used an updraft gasifier at 350-550 °C and air as the gasification medium (ER 0.2). The results indicate that syngas can be produced by updraft gasifier. When the temperature increase, the H2 and CO rising. The highest H2 and CO content of 27.74% and 20.43% are obtained at 550°C when bentonite applied. HHV and LHV range of 3.38~12.79 MJ/Nm3 and 3.03~11.58 MJ/Nm3, respectively. The maximum carbon conversion efficiency (CCE) and cold gas efficiency (CGE) reach 85.49% and 82.34%. Bentonite has been able to increase the concentration of the gas composition especially H2 and CO and the heating value of syngas.
