Abstract
In this study, the separation performance of propylene and propane on SAPO-17 molecular sieve was investigated by static and dynamic adsorption. The adsorbent possessed good regeneration behavior because the strong adsorption of propylene at room temperature was eliminated by ion exchange treatment. Dynamic adsorption experiments revealed that the kinetic separation selectivity of propylene and propane was as high as 1980, which could be attributed to the energy barrier difference when diffusing through the eight-membered ring of SAPO-17 molecular sieve. The breakthrough experiments verified the good separation performance of the SAPO-17 adsorbent, which suggests that it has considerable application potential in propylene/propane separation.

Abstract
Carbon capture and utilization (CCU) has been proposed as a sustainable alternative to produce valuable chemicals by reducing the global warming impact and depletion of fossil resources. To guarantee that CCU processes have environmental advantages over conventional production processes, thorough and systematic environmental impact analyses must be performed. Life-Cycle Assessment (LCA) is a robust methodology that can be used to fulfil this aim. In this context, this article aims to review the life-cycle environmental impacts of several CCU processes, focusing on the production of methanol, methane, dimethyl ether, dimethyl carbonate, propane and propene. A systematic literature review is used to collect relevant published evidence of the environmental impacts and potential benefits. An analysis of such information shows that CCU generally provides a reduction of environmental impacts, notably global warming/climate change, compared to conventional manufacturing processes of the same product. To achieve such environmental improvements, renewable energy must be used, particularly to produce hydrogen from water electrolysis. Importantly, different methodological choices are identified that are being used in the LCA studies, making results not comparable. There is a clear need to harmonize LCA methods for the analyses of CCU systems, and more importantly, to document and justify such methodological choices in the LCA report.

RSC Adv 2018; 8:13728-13738. [PMID: 35539334 PMCID: PMC9079857 DOI: 10.1039/c7ra12917c] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/30/2017] [Accepted: 03/06/2018] [Indexed: 11/23/2022] Open
Abstract
The low contact efficiency, large mass transfer resistance and high operational cost of traditional 13X molecular sieve particle adsorbents (MSPs) have greatly limited their application in deep purification of trace oxygenated compounds from gaseous olefins. Herein, we successfully fabricated dense and thin 13X molecular sieve membranes on a porous α-Al2O3 tube (MSCMs) by a combination of 3-aminopropyl triethoxy silane (APTES) surface modification and vacuum pre-coating sol technology for purifying the above impurities. By a solid–solution transformation process, 13X molecular sieve membranes on MSCMs that were continuous and integral without any cracks, pinholes or other defects, and mainly composed of 1–1.5 μm regular 13X crystals with a thickness of 5–6 μm have been achieved. The purification performance of the MSPs, non-APTES functionalized MSCMs (nMSCMs) and MSCMs was evaluated by dynamic adsorption of N2 or C2H4 feed flow containing dimethyl ether, methanol and propanal impurities at room temperature. The results demonstrated that both the nMSCMs and MSCMs could deeply purify the trace amounts of the three oxygenated compounds to below 1 × 10−6 (mol mol−1) from gaseous olefins at an initial concentration of 20 × 10−6 (mol mol−1), exhibiting much more excellent purification performance than that of MSPs. In particular, the breakthrough times of MSCMs for dimethyl ether, methanol and propanal were 7 h, 32 h and 51 h in a N2 system, and 12.1 h, 53 h and 90 h in a C2H4 system. The cumulative adsorption amounts of MSCMs for dimethyl ether, methanol and propanal were 12.108 mg g−1, 35.812 mg g−1 and 103.129 mg g−1 in a N2 system, and 25.88 mg g−1, 94.19 mg g−1 and 256.26 mg g−1 in a C2H4 system, respectively. The regeneration experiment also indicated that the MSCMs had a more stable structure and a longer lifetime. The excellent purification performance of MSCMs could be attributed to the continuous 13X molecular sieve layers without non-adsorption interfacial voids. Hence, the MSCMs have great potential for future industrial application of trace oxygenated compound removal from gaseous olefins. Dense and thin 13X molecular sieve membranes on porous α-Al2O3 tubes were successfully fabricated by a combination of 3-aminopropyl triethoxy silane surface modification and vacuum pre-coating sol for purifying trace oxygenated compounds from gaseous olefins.![]()
