“…The flash point of the oil from location (1), 210 ± 2 °C, is within the range reported by Gaurav and Sharma, 16 205–270 °C, and much lower than that of canola oil, 315 ± 2 °C, whereas the kinematic viscosity (46.764 mm 2 s –1 at 40 °C) and density (0.9415 g cm –3 at 15 °C), are slightly higher than the reported ranges, 27.84–38.2 mm 2 s –1 at 40 °C and 0.912–0.940 g cm –3 at 15 °C, respectively. 8 …”

The nitrogen content of all the oil samples was not included, as the values were below the detection limit (<200 ppm based on the ∼50 mg sample used for analysis, LECO CHN628 system N detection limit: 0.01 mg).…”

“…Millettia pinnata , also called karanja or pongamia, is indigenous to the Indian subcontinent and Southeast Asia; it is a monotypic genus with a single known species . As a nitrogen-fixing and self-pollinating tree, pongamia can be cultivated easily, even in nonfertile lands and waste lands, and is often found in humid and subtropical environments , with minimum mean monthly temperatures ranging from 10 to 50 °C. Optimal growth requires temperatures in the range of 16–40 °C .…”

Pongamia, a leguminous, oilseed-bearing tree, is a potential resource for renewable fuels in general and sustainable aviation fuel in particular. The present work characterizes physicochemical properties of reproductive materials (seeds and pods) from pongamia trees grown in different environments at five locations on the island of Oahu, Hawaii, USA. Proximate and ultimate analyses, heating value, and elemental composition of the seeds, pods, and de-oiled seed cake were determined. The oil content of the seeds and the properties of the oil were determined using American Society for Testing and Materials and American Oil Chemist’s Society methods. The seed oil content ranged from 19 to 33 wt % across the trees and locations. Oleic (C18:1) was the fatty acid present in the greatest abundance (47 to 60 wt %), and unsaturated fatty acids accounted for 77 to 83 wt % of the oil. Pongamia oil was found to have similar characteristics as other plant seed oils (canola and jatropha) and would be expected to be well suited for hydroprocessed production of sustainable aviation fuel. Nitrogen-containing species is retained in the solid phase during oil extraction, and the de-oiled seed cake exhibited enrichment in the N content, ∼5 to 6%, in comparison with the parent seed. The pods would need further treatment before being used as fuel for combustion or gasification owing to the high potassium and chlorine contents.

“…These selected trees, then serve as a base material for the selection of elite trees through progeny testing and are then used in large scale plantations. Areas of high Pongamia diversity which can be exploited for collection of diverse germplasm have been identified in India (Kaushik et al, 2007(Kaushik et al, , 2015Mukta et al, 4.4.

“…However, to our knowledge, the direct comparison of the effect of support materials including Al 2 O 3 , SiO 2 , and TiO 2 on catalytic activity and stability tests over typical NiMo bimetallic sulfide catalysts especially on unpurified crude has not been fully investigated in the literature. In addition, Pongamia pinnata is currently a feedstock of interest for ester-based biodiesel production but there are rather limited studies on its conversion to bio-hydrogenated diesel [29][30][31]. Moreover, there is a lack of study on the catalyst stability by using Pongamia pinnata oil as a feedstock.…”

Catalytic Hydrotreating of Crude Pongamia pinnata Oil to Bio-Hydrogenated Diesel over Sulfided NiMo Catalyst

This work studied the catalytic activity and stability of Ni-MoS2 supported on γ-Al2O3, SiO2, and TiO2 toward deoxygenation of different feedstocks, i.e., crude Pongamia pinnata oil (PPO) and refined palm olein (RPO). PPO was used as a renewable feedstock for bio-hydrogenated diesel production via catalytic hydrotreating under a temperature of 330 °C, H2 pressure of 50 bar, WHSV of 1.5 h−1, and H2/oil (v/v) of 1000 cm3/cm3 under continuous operation. The oil yield from a Soxhlet extraction of PPO was up to 26 wt.% on a dry basis, mainly consisting of C18 fatty acids. The catalytic activity in terms of conversion and diesel yield was in the same trend as increasing in the order of NiMo/γ-Al2O3 > NiMo/TiO2 > NiMo/SiO2. The hydrodeoxygenation (HDO) activity was more favorable over the sulfided NiMo supported on γ-Al2O3 and TiO2, while a high DCO was observed over the sulfided NiMo/SiO2 catalyst, which related to the properties of the support material and the intensity of metal–support interaction. The deactivation of NiMo/SiO2 and NiMo/TiO2 occurred in a short period, due to the phosphorus and alkali impurities in PPO which were not found in the case of RPO. NiMo/γ-Al2O3 exhibited the high resistance of impure feedstock with excellent stability. This indicates that the catalytic performance is influenced by the purity of the feedstock as well as the characteristics of the catalysts.
