High energy penalty in amine-based solvent regeneration process is a critical challenge industrial application for post-combustion CO2 capture technology. Recently, many efforts have been made to devise strategies lowering the requirement, such as using efficient blended amine systems combine advantages of different amines and/or adding solid acid catalysts. This perspective aims at reviewing most recent advances and opportunities reduce cost by applying various catalysts process. By...
Mixing amines with different properties is considered a smart strategy for developing efficient aqueous solutions reversible CO2 capture. Specifically, dual-amine blends containing the tertiary amine 2-dimethylamino-2-methyl-1-propanol (2DMA2M1P) have proven to be particularly advantageous due significantly lower regeneration costs compared conventional sorbents. With aim of formulating high-efficiency sorbents, in this work we evaluated improvement capture performance such by adding further...
Renewable green fuels (RGF) such as hydrogen are the global energy future. Air pollution is compounded with climate change emissions driving both development problems come largely from same source of fossil fuel burning. As an exporter, Australian export dominates total production and RGF has become central to current proposal government reach net zero emission. The solar panels only on 3% Australia's land area could compensate 10 times Germany's non-electricity consumption. In unique...
Recently, the development of efficient solid acid catalysts to promote CO2 desorption rate while reducing energy consumption has attracted much attention. In this work, low-cost environmentally friendly sepiolite (SEP) clay was evaluated as a support metal oxide (Fe2O3, CuO) catalysts. By comparing their catalytic performances for from CO2-rich monoethanolamine (MEA) solution at 100 °C, obtained results showed that tested can accelerate release and reduce heat in comparison with...
The use of catalysts to promote sorbent regeneration is currently considered an effective method reduce the energy required in CO2 capture processes. Aiming at identifying stable and cost-effective with high desorption efficiency, here we investigated performance fly ash (FA) during thermal aqueous amine solutions. rate, cyclic capacity heat duty a CO2-saturated ethanolamine addition FA were experimentally measured, results compared those obtained for same solution without eight different...
The use of solid acid catalysts for sorbent regeneration is an emerging approach to improve the energy efficiency CO2 capture processes. In this study, fly ash (FA), industrial byproduct rich in acid/base sites, was chosen as a support material SO42−/ZrO2 (SZ) preparation SZ@FA composite catalysts. Three with different mass ratios between SZ and FA were synthesized evaluated process at 88 °C CO2-saturated MEA solution. Their desorption performance, expressed rate, amount desorbed, heat duty,...
Methane has enormous potential as a carrier for renewable H2. The required infrastructure methane gas economy is readily available, and it can compete with its energy-intensive liquefied hydrogen (LH2) counterpart. In this work, we conducted technoeconomic analysis of the production synthetic (LSM) from ambient CO2 process entails (1) capture directly air, referred to Direct Air Capture (DAC) using an amine-based system; (2) generation H2 sources, (3) conversion methane; (4) liquefaction...
The indirect-heated calcium carbonate looping (IH-CCL) process is an advanced carbon capture technology. It eliminates the need of energy intensive air separation unit that required in conventional oxy-fired process, thereby potentially leading to lower consumption and cost. IH-CCL has not been well studied for application existing cement industry with minimized modification current plant. This paper presents a techno-economic feasibility assessment retrofitting into plant understand CO2...
