“…6.b. The vibrational pyridine coordinated to Lewis sites is appeared at 1630 and 1457 cm -1 , while the pyridium ion sorbed on S=O bond of Brønsted sites is observed at 1545 cm -1 [17][18][19][20] . Overall, it can be evident that the increasing Brønsted sites mainly occur in the addition of sulfate groups (S=O bond) and the increasing Lewis sites is equivalent to the increasing amount of nickel metal.…”

Catalytic activity and selectivity toward liquid fuels production of ZrO2, SZ, 0.5NiSZ, 1.0NiSZ, and 1.5NiSZ catalysts with different physicochemical properties, in hydrocracking process upon the second stage of sequential LDPE plastic conversion method after pyrolysis process, were examined. The hydrocracking reaction was carried out at 300°C under 20 mL/min of hydrogen gas flow for 1 h. Modifying commercial ZrO2 with sulfate and Ni enhances the acidity of catalyst, even though there is a decrease in surface area. The increase in acidity of catalyst results in the higher liquid fuels conversion. The presence of nickel reduces olefins content and aromatic content of liquid product, and also reduces coke formation. The highest liquid yield (44.32%) that composed by 66.25% fraction of gasoline is produced over 1.5NiSZ which has the highest catalyst acidity.

The objective of this research was to prepare low-cost catalyst for green diesel conversion from vegetable oil. The catalyst of nickel-dispersed biochar (Ni/BC) was prepared by direct pyrolysis of nickel precursor with palm leaves waste under N2 stream at 500 °C. The obtained catalyst was examined by using x-ray diffraction, scanning electron microscope-energy dispersive x-ray, transmission electron microscopy, gas sorption analysis, FTIR and surface acidity examination. The catalytic activity testing was performed on rice bran oil hydrodeoxygenation at varied temperature and time of reaction. Based on analyses, the results showed the successful preparation of Ni/BC with the characteristic of single nickel nanoparticles decorated on surface. The increasing specific surface area of material was conclusively remarked the surface area enhancement by nickel dispersion along with the increased surface acidity, suggesting that the material can be applied for acid catalysis applications. The Ni/BC exhibited excellent catalytic conversion of rice bran oil with the high selectivity toward diesel fraction with 85.3% yield and 92.6% selectivity.

This project introduces green chemistry to the undergraduate laboratory through two pedagogical techniques: undergraduate research and guided-inquiry. Through these two learning activities, an efficient synthetic procedure for the PRINS cyclization of citronellal into isopulegol, focused on minimizing negative environmental impact, was developed. This project involved two stages. First, a senior undergraduate student applied the principles of green chemistry to the cyclization of citronellal, a naturally occurring aldehyde, into isopulegol, a commercially important compound. The cyclization reaction was achieved in high yield with montmorillonite (MK10) catalyst in buffer medium at room temperature stirring for 2 h. Second, the student researcher, with faculty supervision, transformed this study into a laboratory experiment for Organic Chemistry II students, using inquiry-based pedagogy. Through this project, the student researcher gained experience applying green chemistry principles in the field and in the classroom. The organic chemistry students likewise benefitted, as they gained autonomy, interest in green chemistry, and confidence in the research process, according to the results of a student survey. Thus, this study allowed both the student researcher and the organic chemistry students to expand their experience, autonomy, and appreciation for and application of green chemistry.
