“…In such a way, sodium carbonate yields a higher amount of green aviation kerosene, followed by green diesel and green gasoline. Similar results were reported by Kurniawan et al [83], which produced a range of bio-hydrocarbons from the catalytic pyrolysis of coconut oil soap, most of which proved to be similar to jet fuel.…”

This work systematically investigated the influence of catalyst reuse and reaction time on the yield and quality of organic liquid products (OLP) obtained in a cracking pilot plant at 450 °C and 1.0 atm. The distillation of OLP produced 04 (four) distilled fractions (gasoline, kerosene, and green diesel). The biofuels-like fractions are liquid mixtures with high content of hydrocarbons (alkanes, alkenes, and aromatics) with potential application as substitutes for fossil fuels in internal combustion motors. The quality of the biofuels was certified by physical-chemical analysis and FT-IR and GC-MS analysis. The experimental results showed the feasibility of applying the spent sodium carbonate twice in the catalytic cracking of vegetable oils. The physical-chemical properties (density, viscosity, acid value, saponification value, and flash point) of OLP decrease as the reaction time increases. The distillation of OLP yields 62.35% (wt.), producing green-like gasoline, kerosene, and diesel fractions rich in hydrocarbons. Therefore, biofuel-like fractions produced by distillation of OLP have a great potential for replacing partially petroleum-derived fuels.

“…Despite the importance of the dealumination of zeolites for improving the properties of catalytic materials, the chemical modification of natural mordenite, one of the most abundant zeolites worldwide, has been comparatively little studied. Kurniawan et al [22] compared a natural Indonesian mordenite with a synthetic faujasite for the production of bio-hydrocarbon oils from coconut soap. Meanwhile Fani and co-workers investigated the valorization of a natural Greek mordenite for use as support in a Ni catalyst to upgrade biodiesel into renewable diesel [23].…”

Dealumination and Characterization of Natural Mordenite-Rich Tuffs

The present study evaluates the feasibility of partially dealuminated natural mordenite as a catalyst support by studying improvement in its textural properties. This is the first study that reports the dealumination of natural zeolite-based tuffs from Ecuador. For this purpose, mordenite-rich tuffs were obtained from deposits close to Guayaquil, Ecuador. The raw material was micronized in order to increase its surface, and treated with NH4Cl. NH4+ cation-exchanged samples were finally reacted with HCl(aq) to complete the dealumination process. The partially dealuminated samples were characterized using techniques such as XRD, FT-IR, SEM-EDS, and identification of their textural properties. Dealumination with HCl(aq) increased the Si/Al ratio up to 9 and kept the crystallographic structure of natural mordenite, as XRD results showed that the structure of mordenite was not altered after the dealumination process. On the other hand, textural properties such as surface area and microporosity were improved as compared to natural mordenite. In view of these results, the feasibility of using natural mordenite as a catalyst support is discussed in this study.

“…Quanto maior o aumento de temperatura, maior será a formação de gás e menor será o ganho de líquido, deve-se ao aumento das reações de craqueamento, contudo, para diminuição do teor de oxigênio é exigido do processo uma alta temperatura, por isso é muito importante ter atenção com as reações de craqueamento (MORTENSEN et al, 2011). Diversos estudos têm mostrado cada vez mais as possibilidades de utilização das zeólitas, sendo um campo com constantes avanços (KURNIAWAN et al, 2021;FERMANELLI et al, 2021;WIKBERG, 2019;CHEN et al, 2018;HERNANDO et al, 2018;VESES et al, 2016).…”

Este trabalho teve como objetivo definir o melhor solvente extrator e sistema de extração para determinação dos compostos fenólicos totais, capacidade antioxidante e antocianinas monoméricas totais do fruto do grumixama. Foram testados diferentes solventes (água, acetona, etanol e metanol), utilizados individualmente e em misturas, bem como diferentes sistemas de extração (agitação magnética à temperatura ambiente, agitação magnética sob refrigeração e escuro e banho ultrassônico à temperatura ambiente). Os resultados mostraram que a acetona / água (80:20, v / v) e a agitação magnética à temperatura ambiente maximizaram a extração dos compostos fenólicos totais e proporcionaram a maior capacidade sequestrante do radical DPPH.Para as antocianinas monoméricas totais, etanol 1,5 M HCl e metanol 1,5 M HCl demonstraram os melhores resultados como solventes de extração. Esses resultados indicam a influência de solventes e sistemas de extração aplicados no rendimento e qualidade dos extratos, além de reforçar o potencial da fruta grumixama em relação ao seu conteúdo fenólico e capacidade antioxidante.
