Separation of Branched Alkane Feeds with Metal-Organic Frameworks
Henrique, Adriano; Brântuas, Pedro; Zafanelli, Lucas F.A.S.; Aly, Ezzeldin; Rodrigues, Alírio; Maurin, Guillaume; Serre, Christian; Silva, José A.C.The production of high-quality gasoline is currently achieved through the Total Isomerization Process that separates n/iso-paraffins in the pentane (C5) and hexane (C6) range while not reaching the ultimate goal of a research octane number (RON) higher than 92. This work demonstrates two promising alternatives/strategies using metal-organic frameworks (MOF) that lead to a novel adsorptive separation process to ...

Separation of Branched Alkanes Feeds by a Synergistic Action of Zeolite 5A and ...
Henrique, Adriano; Brântuas, Pedro; Zafanelli, Lucas F.A.S.; Aly, Ezzeldin; Rodrigues, Alírio; Maurin, Guillaume; Serre, Christian; Silva, José A.C.The total isomerisation process (TIP) developed by the universal oil products (UOP) for upgrading the octane rating of light hydrocarbon fractions, especially mixed feedstocks containing pentane (C5) and hexane (C6) isomers, is among the first and most successful adsorption processes applied in the industry. Typically, the light naphtha, characterised by a low research octane number (RON, ≈70), undergoes an inc...

Zhou, Lin; Brântuas, Pedro; Henrique, Adriano; Reinsch, Helge; Wahiduzzaman, Mohammad; Grenèche, Jean‐Marc; Rodrigues, Alírio; Silva, José A.C.The improvement of the Total Isomerization Process (TIP) for the production of high-quality gasoline with the ultimate goal of reaching a Research Octane Number (RON) higher than 92 requires the use of specific sorbents to separate pentane and hexane isomers into classes of linear, mono- and di-branched isomers. Herein we report the design of a new multi-cage microporous Fe(III)-MOF (referred to as MIP-214, MIP...

Brântuas, Pedro; Henrique, Adriano; Wahiduzzaman, Mohammad; Wedelstedt, Alexander von; Maity, Tanmoy; Rodrigues, Alírio; Nouar, Farid; Lee, U-HwangZeolites and metal-organic frameworks (MOFs) are considered as “competitors” for new separation processes. The production of high-quality gasoline is currently achieved through the total isomerization process that separates pentane and hexane isomers while not reaching the ultimate goal of a research octane number (RON) higher than 92. This work demonstrates how a synergistic action of the zeolite 5A and the MI...
Hexane isomers separation on an isoreticular series of microporous Zr carboxyla...
Henrique, Adriano; Maity, Tanmoy; Zhao, Hengli; Brântuas, Pedro; Rodrigues, Alírio; Nouar, Farid; Ghoufi, Aziz; Maurin, Guillaume; Silva, José A.C.A series of isoreticular Zr carboxylate MOFs, MIL-140A, B and C, exhibiting 1D microporous triangular shaped channels and based on different aromatic dicarboxylate ligands (1,4-BDC, 2,6-NDC and 4,4′-BPDC, respectively), were investigated by chromatographic breakthrough experiments regarding their ability to separate hexane isomers (nC6/2MP/3MP/23DMB/22DMB). Both single and equimolar multicomponent experiments w...
Fixed bed dynamics of multicomponent adsorption of pentane and hexane isomers i...
Brântuas, Pedro; Henrique, Adriano; Rodrigues, Alírio; Silva, José A.C.The separation of hydrocarbon mixtures is one of the most important topics in the petrochemical industry, including the separation of paraffins isomers in the C5/C6 range for the octane upgrading of gasoline. These processes separate low Research Octane Number (RON) linear paraffins, n-hexane (nC6) and n-pentane (nC5), from their respective branched isomers with higher RON content: 3-methylpentane (3MP), 2-meth...

Karimi, Mohsen; Brântuas, Pedro; Henrique, Adriano; Gonçalves, Carmem Natália de Pina; Silva, José A.C.; Rodrigues, AlírioIn this study, based on the scopes of CCS strategy and municipal solid waste management, a novel Integrated Environment Management (IEM) strategy has been proposed. In this way, the obtained compost in the mechanical biological treatment from municipal solid wastes has been considered as a source of adsorbents for CO2 capture. In this way, the maturated compost waste was modified by liquid phase treatment with ...
Equilibrium adsorption of CO2, CH4 and N2 on BETA zeolites at post-combustion o...
Karimi, Mohsen; Brântuas, Pedro; Henrique, Adriano; Silva, José A.C.; Rodrigues, AlírioThe adsorption equilibrium and kinetics of CO2,CH4, and N2 on three types of BETA zeolites were investigated at different temperatures and a defined partial pressure range from dynamic breakthrough experiments. The adsorbed amount followed the decreasing order of CO2>CH4>N2 for all studied materials. For the same ratio of SiO2/Al2O3, the Na-BETA-25 zeolite showed a higher uptake capacity than H-BETA-25, due to ...
