“…This tendency is in agreement with the literature as well as with the kinetic of the transesterification reaction under the catalytic effect of Li 2 SiO 3 . Cherikkallinmel and co-workers [ 37 ] achieved biodiesel production using Li 2 SiO 3 through Box–Behnken design, where the optimized conditions to maximize the yield of biodiesel production were reported being those close to the results obtained herein. However, in that study the authors used reagent grade and conventional precursors to synthesize the employed catalysts.…”

A facile and versatile process to produce lithium metasilicate (Li2SiO3) from non-conventional silicon sources (two different sand sources from the central area of México) was developed. The synthesis protocol based on a solid-state reaction followed by a hydrothermal treatment resulted in highly pure lithium metasilicate, as corroborated by XRD, SEM-EDS, and XPS analysis. Furthermore, lithium metasilicate was used as a heterogeneous catalyst for biodiesel production from soybean oil, where conversion yields were compared according to the silicon source used (based on chemical purity, stability, and yield efficiency). The best performing metasilicate material displayed a maximum of 95.5% of biodiesel conversion under the following conditions: 180 min, 60 °C, 5% catalyst (wt./wt., catalyst-to-oil), and 18:1 (methanol:oil). This contribution opens up alternatives for the production of lithium metasilicate using non-conventional precursors and its use as an alternative catalyst in biodiesel production, displaying better chemical stability against humidity than conventional heterogeneous catalysts.

“…However, waste oil is considerably cheaper than pure refined vegetable oils; it is noteworthy that disposal of waste materials like waste cooking may cause health-related risks and the environmental risks (4,5). Waste oil, as a plentiful and sustainable feedstock, can be used for biodiesel production (6), but the extensive pretreatments affect its economic viability since the economic aspects of biodiesel production are of considerable importance for its sustainable preparation (7).…”

“…Recently, the frequency of abnormal weather due to global warming has been increasing, and its intensity has also become stronger than before. For example, the temperature in France in June 2019 approached 45 • C. In this regard, the use of renewable energy is essential to reduce global warming, the main cause of climate change, and biofuels are a significant source of renewable energy [1][2][3][4][5]. Among the biofuels, the importance of bio-oil is increasing because it can be used both as a biofuel and as chemical feedstock.…”

In-Situ Catalytic Fast Pyrolysis of Pinecone over HY Catalysts

et al. 2019

The in-situ catalytic fast pyrolysis of pinecone over HY catalysts, HY(30; SiO2/Al2O3), HY(60), and 1% Ni/HY(30), was studied by TGA and Py-GC/MS. Thermal and catalytic TGA indicated that the main decomposition temperature region of pinecone, from 200 to 400 °C, was not changed using HY catalysts. On the other hand, the DTG peak heights were differentiated by the additional use of HY catalysts. Py-GC/MS analysis showed that the efficient conversion of phenols and other oxygenates formed from the pyrolysis of pinecone to aromatic hydrocarbons could be achieved using HY catalysts. Of the HY catalysts assessed, HY(30), showed higher efficiency in the production of aromatic hydrocarbons than HY(60) because of its higher acidity. The aromatic hydrocarbon production was increased further by increasing the pyrolysis temperature from 500 to 600 °C and increasing the amount of catalyst due to the enhanced cracking ability and overall acidity. The use of 1% Ni/HY(30) also increased the amount of monoaromatic hydrocarbons compared to the use of HY(30) due to the additional role of Ni in enhancing the deoxygenation and aromatization of reaction intermediates.
