“…The BET technique was used to determine a certain surface area. The specific surface area of the currently synthesized catalyst was 165 m 2 /g, which was more than the specific surface area of fresh rice husk /K 2 O-20%/Ni-5% reported by [27] and equivalent to similar literature values [28]. In addition, larger pore diameter catalysts are crucial because they can more easily catalyze chemical processes.…”

This work created, characterized, and used a magnetic biochar catalyst that is both eco-friendly and very effective. Sugarcane bagasse was selected as primary raw material for catalyst preparation, because it is renewable and ecofriendly biomass. Catalyst created by doping sugarcane bagasse biochar with magnetic material in the form of (FeSO4·7H2O). Thermogravimetric Analysis (TGA) and Fourier Transform Infrared spectroscopy (FTIR) were used to characterize the catalyst. In addition, physical and textural characteristics of the catalyst were identified and interpreted. The characterization outcome showed that the catalyst has good catalytic qualities. For the manufacturing of biodiesel, discarded cooking oil served as the primary feedstock. The experiment was created utilizing the Box–Behnken Design (BBD) technique. There are four variables with the following three levels each: temperature, methanol to oil ratio, catalyst concentration, and reaction time. 29 experiments in total were carried out. Using the RSM function, optimization was done. The optimal conditions for obtaining biodiesel yield—temperature, methanol to oil ratio, reaction time, and catalyst weight—were 43.597 °C, 9.975 mol/L, 49.945 min, and 1.758 wt%. A study of the produced biodiesel using a FTIR showed that the conventional biodiesel IR spectra were confirmed. All physiochemical characteristics found suggested the biodiesel complied with ASTM and EN norms. Overall, the synthesized catalyst had conducted simultaneous reactions in a single batch reactor and had demonstrated suitability for converting used cooking oil to biodiesel.

“…Thus, the direct screening of genotypes for higher P n , g s , and WUE i under natural climatic conditions should be advantageous in selecting the germplasm to attain higher productivity. Photosynthetic CO 2 assimilation is crucial to obtain feedstock for biofuel production, which includes lignin (for ethanol), cellulose (for bioethanol), starch (for bioethanol), and oils (for biodiesel) ( Ranadheer et al, 2019 ; Antar et al, 2021 ; Parida et al, 2022 ). Also, it is the ultimate process that produces ATP and NADPH, which are subsequently utilized in the Calvin cycle and other biochemical pathways to produce the sugars, starch, oils, and other bio-molecules that collectively form biomass.…”

Due to rapid industrialization, the consumption of petro-products has increased, while fossil fuel resources have been gradually depleted. There has been a resurgence of interest in plant-derived biofuels as a sustainable alternative to fossil fuels for the purpose of reducing greenhouse gas emissions. Pongamia pinnata L., which is also known as Millettia pinnata is an oil-yielding, leguminous tree with a large and complex genome. Despite its multiple industrial applications, this orphan tree species has inconsistent yields and a limited understanding of its functional genomics. We assessed physiological and morphological characteristics of five high-yielding pongamia accessions and deduced important yield descriptors. Furthermore, we sequenced the genome of this potential biofuel feedstock using Illumina HiSeq, NextSeq, and MiSeq platforms to generate paired-end reads. Around 173 million processed reads amounting to 65.2 Gb were assembled into a 685 Mb genome, with a gap rate of 0.02%. The sequenced scaffolds were used to identify 30,000 gene models, 406,385 Simple-Sequence-Repeat (SSR) markers, and 43.6% of repetitive sequences. We further analyzed the structural information of genes belonging to certain key metabolic pathways, including lipid metabolism, photosynthesis, circadian rhythms, plant-pathogen interactions, and karanjin biosynthesis, all of which are commercially significant for pongamia. A total of 2,219 scaffolds corresponding to 29 transcription factor families provided valuable information about gene regulation in pongamia. Similarity studies and phylogenetic analysis revealed a monophyletic group of Fabaceae members wherein pongamia out-grouped from Glycine max and Cajanus cajan, revealing its unique ability to synthesize oil for biodiesel. This study is the first step toward completing the genome sequence of this imminent biofuel tree species. Further attempts at re-sequencing with different read chemistry will certainly improve the genetic resources at the chromosome level and accelerate the molecular breeding programs.

“…As such, it contrasts with more specialized surveys of the recent literature on chemical engineering aspects of biodiesel production [27] and the use of specific catalyst feedstocks, e.g. animal-based biomass [28], industrial waste [29], or lignocellulosic material [30]. Turning to methods for enhancing catalyst activity (e.g., calcination, doping), we particularly outline recent advances by ourselves and others in the development of sulfonated catalysts in the context of limiting active site leaching and/or regenerating spent catalysts.…”
