“…Hence, it was concluded that no significant CH 4 adsorption occurs on Lewatit or that CH 4 adsorption on Lewatit is at least not detectable with the applied method. This is also in line with CH 4 adsorption studies with other amine-functionalized materials [39] and with findings from Sutanto et al for Lewatit [36].…”

“…The received CO 2 isotherms for Lewatit match the capacities reported by Yu et al [12], who reported 2.15 mol kg −1 (40°C, p CO2 0,15 bar) and Sutanto et al [36] (Toth model by Sutanto et al displayed in Fig. 7) but are below the capacities reported by Veneman et al [35].…”

“…However, the simplified model used in this study did not consider for any heat integration measures such as previously proposed by Pröll et al [14], Vogtenhuber et al [46], or Sutanto et al [36]. Hence, one can expect that the specific regeneration energy demands derived in this work can be further reduced, if such measures are applied to the TSA process.…”

“…These previous studies assessed the adsorption behavior of CO 2 and H 2 O on Lewatit for the purpose of carbon capture from flue gas. However, so far, Lewatit has not been considered for utilization in biogas upgrading applications, except by Sutanto et al in their recently published study [36]. Hence, only little information on CO 2 /CH 4 separation properties of Lewatit are available.…”

Two commercially available CO 2 -adsorbent materials (i.e., zeolite 13X (13X) and Lewatit® VP OC 1065 (Lewatit)) were evaluated for their applicability in a continuous temperature swing adsorption (TSA) process for biogas upgrading. The equilibrium adsorption characteristics of carbon dioxide and methane were determined by fixed bed and TGA tests. While relatively high CO 2 capacities were measured for both materials (3.6 and 2.5 mol kg), neither of them was found to adsorb significant amounts of CH 4 . Lewatit showed to be fully regenerable at 95°C, whereas for 13X, the regeneration was not complete at this temperature. However, 13X showed no degradation up to 190°C, whereas Lewatit started to degrade at 110 and 90°C when exposed to N 2 and air, respectively. Fluidization tests showed that Lewatit provides a high mechanical stability, while on the contrary, the tested 13X showed considerable attrition. An equilibrium adsorption model was fitted to the measured CO 2 adsorption data. The adsorption model was then integrated into an existing simulation tool for the proposed TSA process to roughly estimate the expectable regeneration energy demand for both materials. It was found that depending on the operating conditions, the regeneration energy demand lies between 0.32-0.54 kWh th /m 3 prodgas for 13X and 0.71-1.10 kWh th /m 3 prodgas for Lewatit. Since heat integration measures were not considered in the simulations, it was concluded that the proposed TSA process has a great potential to reduce the overall energy demand for biogas upgrading and that both tested adsorbent materials may be suitable for application in the proposed TSA process.

“…Due to the fact that the biogas resulted was in very small amount, without pressurized storage, the adopted solution was to use some similar gas compositions prepared by a specialised company. In papers [2][3][4][5] are presented biogas compositions with a CH 4 weight of about 55% and a CO 2 weight of 45%, similar to those obtained by anaerobic --------------* Corresponding author, e-mail: gabriel.negreanu@upb.ro S1350 THERMAL SCIENCE: Year 2018, Vol. 22, Suppl.…”

Influence of the characteristics of biogas generated in the leather industry on combustion quality

et al. 2018

The treatment of protein waste in the leather industry also includes transformation into biogas through anaerobic digestion. A pilot plant producing biogas with a 45-60% CH 4 concentration was designed for this purpose. Starting from primary experimental tests in a Bunsen burner, the paper presents the theoretical aspects of choosing the best combustion technique for this peculiar gaseous fuel in order to calculate the combustion velocity and checking the conditions for the flame stability. The applicability of the kinetic combustion (with pre-mix) will be attempted, because low combustion rates for this fuel also involve low air velocities. Diffusive combustion seems to not be affected by this impediment, as there is always an equality condition of flame velocity with burning speed, so a theoretical spot of a stable flame. After selecting the best combustion technique, a pilot burner will be designed and tested.

The aim of this work was to evaluate the performance of three different supported amine sorbents in a 6-step vacuum swing adsorption (VSA) cycle through process simulation and optimization for a representative post-combustion CO 2 capture system. Detailed process optimization revealed that all the adsorbents were able to achieve the desired purityrecovery targets. The best performing adsorbent in terms of productivity was Lewatit with a productivity of 0.48 mol m -3 ads s -1 . All the adsorbents exhibited similar minimum specific energy value of around 1 MJ kg -1 on an electric basis.
