“…However, very little techno-economic evaluation of biomass chemical looping processes (BCLPs) have been conducted, with even less focused on biomass chemical looping gasification to power generation as reviewed by [14]. Typically, Xu et al only investigated chemical looping partial oxidation process for thermochemical conversion of biomass to syngas without considering the following power generation process [23]. Gopaul et al compared to two chemical looping gasification processes for unique hydrogen production: one scheme produces H2 using a CaO sorbent for CO2 capture and total sorbent recovery; another scheme produces H2 using Fe-based oxygen carriers for near-total carrier recovery [24].…”

Sawdust direct gasification using chemical looping with hematite as an oxygen carrier was investigated in a 10 kWth interconnected fluidized bed reactor. This was used to develop a biomass chemical looping gasification combined cycle (BCLGCC) model using Aspen Plus software. A technical analysis of a scaled up, simulated and validated 650 MW power plant using BCLG experimental results and industrial data was conducted. The analysis focused on investigating critical parameters that have a significant effect on syngas quality and quantity, hence optimizing the gasification process to obtain higher energy efficiencies for subsequent power generation. An economic and sustainability assessments comparing BCLGCC with 4 different power generation technologies with and w/o CCS was performed.BCLGCC presents promising economic and environmental results, showing that the

“…A similar result could also be found in a study on iron ore as an oxygen carrier to oxidize biomass char in a fixed bed reactor. 18 This can be explained that excess lattice oxygen promoted the reactions shown in reactions (7) and (8). The combustible gases were consumed with the generation of CO 2 and H 2 O.…”

“…Additionally, without an active role, Al 2 O 3 was used as the bed material for the blank The effect of OC and WAC mole ratio on gas distribution and LHV is shown in Figure 3a. H 2 is consumed at first, due to the low activation energy as shown in the reaction (7). Thus, H 2 content gradually decreases with the increase of OC/WAC.…”

“…6 At present, along with transition metal oxides, i.e., Ni, Cu, Co, Mn, Fe, that have been investigated as possible oxygen carriers for the CLG process, synthetic oxygen carriers are widely researched, while natural minerals are potentially developed. 7,8 From which, iron ore as a natural OC was largely used due to its low cost, environmental-friendliness and sulfur resistance. 9,10 And it indicated that the iron-based oxygen carrier promoted tar cracking and reforming during biomass gasification process, which resulted in increased syngas production.…”

Waste Activated Carbon (WAC), as a typical solid waste, can be utilized by Chemical-Looping Gasification (CLG) technology with an iron-based Oxygen Carrier (OC) to produce valuable synthesis gas. A series of experiments on WAC of the CLG process has been performed in a fixed-bed reactor. The operation parameters and cyclic performance of the iron-based OC have been investigated during CLG reactions. Fresh and cyclic reaction OC samples have been analyzed by X-Ray Diffraction (XRD) and Scanning Electron Microscopy (SEM). To obtain high-quality syngas with high carbon conversion, the optimal OC/WAC mole ratio, steam flow rate and reaction temperature are 0.1, 0.10 mL/min, and 950 °C, respectively. The iron-based OC exhibits a stable cyclic performance during multiple tests, following the reaction path of Fe2O3 to Fe0.98O in the individual reduction process. Moreover, the iron-based OC is oxidized to almost its initial state after 10 redox tests without obvious sintering and agglomeration phenomena. The WAC of CLG provides a new approach to the comprehensive usage of solid waste, especially with low volatile feedstock.

In this work, three catalysts (Ni-based catalyst, Ni/Fe-based catalyst, and Ni/Cebased catalyst) were developed for catalytic cracking of toluene as a model compound of tar in a fixed bed reactor. The characteristic of catalysts were determined by XRD, EDX, and BET. Meanwhile, the effects of calcination temperature and reaction temperature on syngas yield and toluene conversion rate were also studied. The results showed that the BET surface area was decreased with the rise of calcination temperature, while the content of hydrogen and syngas yield were decreased with the rise of calcination temperature. The three catalysts showed a promising application in catalytic reforming of toluene for hydrogen production. The catalytic performance of three catalysts was ordered as Ni/Ce > Ni/Fe > Ni > thermal cracking. The maximum syngas yield (1.44 L/g toluene) and toluene conversion rate (96.4%) were obtained for Ni/Ce-based catalyst, which indicated the effectiveness of the Ni/Cebased catalyst.
