Inert property of ZrO2 in CLG Figure S1 shows the weight profile of ZrO2 with 5% H2 in a TGA test at 900°C. During the 27 min of flowing with 5%H2, the weight of ZrO2 has bare changes. This confirms clearly that the ZrO2 we used in the bed is inert and doesn’t react with the microalgae or its fuel gases. S2. CO2 uptake/release from LD Slag Figure S2 below shows the CO2 release and CO generation with the LD Slag oxygen carrier. This phenomenon was observed during the N2 purge period after the CO+CO2 prereductions. Ilmenite is presented in the figure for comparison, as this material is known incapable for CO2 release and CO generation. As seen in the figure, when using ilmenite, the CO2 concentration drops rapidly at the beginning and then reaches a relatively stable value of lower than 0.3% while the CO drops quickly to zero. On the contrary, when using the LD slag, the CO2 and CO were maintained at around 2-3% and 1-2% after the rapid decline. Figure S2. (a) CO2 release and CO generation from 200 g LD slag with Xox,des=0.2 at 850°C, and the 200 g ilmenite is presented for comparison, (b) effect of temperature (850, 900 and 950°C) and desired oxidation degree (Xox,des=0.2 and 0.5) on the CO2 release and CO generation when using LD slag. CO2 for the case of Xox,des=1 is not available because it doesn´t have prereduction steps. The effects of LD Slag oxidation degree and temperature on CO2 release and CO generation are presented in Figure S1(b). As explained in our experimental plan, there are more oxygen carrier particles available when the desired oxidation degree is lower, e.g., when the Xox,des is 0.2 there are 200 g oxygen carriers in the bed while it is 40 g, Xox,des is 1. The effect of oxygen carrier amount on the CO2 release is clear; the more oxygen carrier particles lead to higher CO2 release. In addition, the increase in operation temperature leads to less CO2 release, because the carbonation (the reverse reaction of reaction r4) is exothermic, and higher temperatures hinder the formation of more CaCO3 which is responsible for the CO2 release. All these indicate the LD slag’s capability of releasing CO2 and simultaneously generating CO from CO2 splitting with the reduced LD slag. S3. SEM images of the fresh oxygen carrier The Figure S3 below presents the SEM images of bulk particles before use in the batch reactor experiments. The ilmenite has been used in previous campaign with biomasses in the 20 kWth unit, therefore it has been activated and has some cracks on the particles´ surface, see Figure S3-A. The MnGBhne has some fines (Figure S2-B) before the batch experiments, but after the tests, fines are not seen. The LD slag has a lot of fine particles before the batch reactor tests (see Figure S2-C), and there are still some fines after use in the reactor, see Figure 12 in the paper. Iron sand in both fresh and used forms has well-sintered surface and has some spherical particles. S3. ICP-AES analysis of calcium content in LD slag and iron sand Table S1 presents the content of calcium in the LD slag and iron sand, before and after use with the microalgae in the batch reactor. Basically, the Ca content hasn’t changed during the cycles with microalgae in the reactor. This might be attributed to the even distribution of calcium in the LD slag and iron sand, and thus the used particles have a same calcium concentration. Table S1. ICP-AES analysis of calcium content (with a small uncertainty) in the calcined and used LD slag and iron sand. S4. Water splitting reaction The water splitting can happen when there is free wüstite (FeO) or metallic iron (Fe) in the reacting environment. The four oxygen carriers all have FeO or Fe available after the prereduction with CO, and water splitting reactions are clearly seen when switching from the CO prereduction condition to steam condition. Figure S4 below displays the H2 profiles from the water splitting for the four oxygen carriers with the desired oxidation degree Xox,des of 0.2 at 850, 900 and 950°C. Clearly, the four oxygen carriers have different capability for H2 generation. Ilmenite has the lowest H2 concentration (1-1.5%) at all the three temperatures. The increase of temperature generally improves the H2 concentration with ilmenite, MnGBhne and LD slag, but hinders the water splitting reaction with the iron sand, and thus less H2 is seen at higher temperatures with the iron sand. Among the four oxygen carriers, LD slag presents the highest H2 concentrations (9.5-13%) at the three temperatures, and LD slag´s prominent performance for H2 generation from the water splitting is also observed when the oxygen carriers are half reduced (Xox,des=0.5, the 80/120 case) which are not shown here. Therefore, the splitting reaction is more relevant when using LD slag as compared to the other three oxygen carriers, and the water splitting could happen when the gasification is complete as there is still steam flowing to the reactor. Figure S4. H2 concentrations during the water splitting prior to the microalgae injection when the desired Xox,des is 0.2 with 200 g oxygen carriers in the bed at the three temperatures. The final H2 increases with ilmenite and MnGBhne are due to the volatiles release because there the fuel injection started.This work was funded by the CLG-G3BioF project that received funding from the Horizon Europe Framework Programme under Marie Sklodowska-Curie grant agreement (No.101110366).
