“…12,13 On the other hand, for countries with agro-based economies, biogas upgrading by the PSA process using biomass-based adsorbents would help promote their local economies. 14,15 Recent studies showed that AC is a promising adsorbent for carbonbased greenhouse gases, and the modification of AC could increase its selective adsorption properties as well as reduce its production costs. 7,12,[16][17][18][19] The PSA process with AC adsorbent might be suitable for upgrading biogas with low CH 4 fraction, e.g.…”

BACKGROUNDBiogas upgrading is the process that increases the fraction of methane (CH4) in biogas, making the biogas suitable for use as vehicle fuel or as fuel with high and stable heating values for combustion engines. The advantages and disadvantages of activated carbon (AC) in CO2/CH4 adsorptive separation should be well understood before application for biogas upgrading. In the first part of this study, characteristics of CO2 adsorption and desorption on AC were investigated using Aspen Adsorption. In the second part, vacuum pressure swing adsorption (VPSA) was modeled, and the performances of the VPSA process using zeolite 13X, carbon molecular sieve (CMS) and AC were compared.RESULTSThe simulations showed that the advantages of AC for CO2 adsorption include relatively high dynamic adsorption capacity and high mass transfer coefficient of CO2 (KLDF,CO2) in AC and consequently relatively high CO2 desorption rates. However, due to the relatively high mass transfer coefficient of CH4 (KLDF,CH4) in AC, the molecular sieving characteristics for CO2 that were estimated from the ratio between KLDF,CO2 and KLDF,CH4 of AC were not significantly higher than that of zeolite 13X and significantly lower than that of CMS (9.85, 8.41 and 20.92 for AC, zeolite 13X and CMS, respectively).CONCLUSIONSThe modeling results predicted that the VPSA process using zeolite, CMS and AC adsorbents gives a biomethane product of around 98%, 97% and 93% CH4, respectively. © 2023 Society of Chemical Industry (SCI).

The study focuses on laboratory testing of carbon-dioxide adsorption. It compares three methods used to determine the capacity of the adsorbents proposed for CO2 capture. The tests have been performed on two samples, namely natural clinoptilolite and a 13X molecular sieve. Two methods were dynamic and one was static. The first dynamic method evaluated the capacity based on the change in CO2 volume fraction before and after a fixed-bed adsorber. For the same purpose, the second dynamic method used a gravimetric procedure. The static method detected a change in pressure during CO2 adsorption. The capacities determined for carbon-dioxide mole fractions of 5, 10, 13 and 20% at temperatures of 30 and 40 °C at atmospheric pressure were compared. The apparatus with a fixed-bed adsorber made it possible to perform tests also for overpressures of 2 and 5 bar and lower temperatures. The capacity obtained on the three apparatuses showed good agreement. The maximum capacity (3.32 mmol g−1) was determined for the 13X sample at 10 °C and a partial CO2 pressure of 120 kPa and, conversely, the lowest (0.12 mmol g−1) for clinoptilolite at 40 °C and a partial CO2 pressure of 5 kPa. There was no significant difference in capacity standard deviations between the apparatus (0.014–0.036 mmol g−1). The fixed-bed apparatus required one to three orders of magnitude more gas for the experiment and was more challenging to operate and evaluate the data.
