“…In that case, noted changes in harmful emissions were accompanied by slightly higher the volumetric fuel consumption under heavy loads due to addition of 50vol% sunflower oil and/or olive oil biodiesel into aviation JP-8 fuel [2].…”

“…The development of biomass derived substitutes for diesel fuel is a possible attractive outlet, as it could help to improve the quality. The bench tests conducted with a single cylinder, stationary direct injection Petter engine, model AV1-LAB showed that the substitution of F-34, which is comparable with commercial aviation fuel JP-8, with sunflower oil and/or olive oil at proportions from 10% to 50% results in slightly increasing the volumetric fuel consumption, a strong tendency to decreasing PM emissions and both positive and negative changes of nitrogen oxide emissions depending on the percentage of biofuel added in the JP-8 and engine load [2].…”

“…The single fuel selected has been the F-34 (JP-8) military jet kerosene, which is based upon the civil jet fuel F-35 (Jet A-1), which is widely available throughout the European arena, with the inclusion of military additive possessing anti-icing and lubricating properties [2].…”

“…In this regard, a previous study (Stettler et al, 2011) has stated: "The First-Order Approximation (FOA3) -currently the standard approach used to estimate particulate matter emissions from aircraft -is compared to measurements and it is shown that there are discrepancies greater than an order of magnitude for 40 % of cases for both organic carbon and black carbon emissions indices". Thus, to assess this inventory over Hyderabad (our study region), we estimated BC emissions from aircraft over this region using previously reported values for the fuel efficiency of different airline carriers (Kwan and Rutherford, 2015), seating capacity of the carriers (websites of different airlines), density of aviation fuel used (Cookson and Smith, 1990;Arkoudeas et al, 2003;Outcalt et al, 2009;Blakey et al, 2011) in the Indian region, BC emission index for the aviation fuel (Stettler et al, 2013) and actual data on air traffic over Hyderabad obtained from air traffic control (Babu et al, 2011). Depending on such an evaluation of the MACCity emissions database over the Hyderabad region, we have modified the inventory emissions by a corresponding scaling factor.…”

Possible climatic implications of high-altitude black carbon emissions

Abstract. On account of its strong absorption of solar and terrestrial radiation, black carbon (BC) aerosol is known to impact large-scale systems, such as the Asian monsoon and the Himalayan glaciers, in addition to affecting the thermal structure of the lower atmosphere. While most studies focus on the near-surface abundance and impacts of BC, our study examines the implications of sharp and confined layers of high BC concentration (called elevated BC layers) at altitudes more than 4 km over the Indian region using the online regional chemistry transport model (WRF-Chem) simulations. These elevated BC layers were revealed in the recent in situ measurements using high-altitude balloons carried out on 17 March 2010, 8 January 2011 and 25 April 2011. Our study demonstrates that high-flying aircraft (with emissions from the regionally fine-tuned MACCity inventory) are the most likely cause of these elevated BC layers. Furthermore, we show that such aircraft-emitted BC can be transported to upper tropospheric or lower stratospheric heights ( ∼ 17 km) aided by the strong monsoonal convection occurring over the region, which is known to overshoot the tropical tropopause, leading to the injection of tropospheric air mass (along with its constituent aerosols) into the stratosphere. We show observational evidence for such an intrusion of tropospheric BC into the stratosphere over the Indian region using extinction coefficient and particle depolarisation ratio data from CALIOP Lidar on-board the CALIPSO satellite. We hypothesise that such intrusions of BC into the lower stratosphere and its consequent longer residence time in the stratosphere have significant implications for stratospheric ozone, especially considering the already reported ozone-depleting potential of BC.

“…Canakci et al [7] claimed that biodiesel CO 2 emissions are offset through photosynthesis. In addition to its carbon offset, biodiesel is nontoxic, contains no aromatics or sulfur, has higher biodegradability, and is less polluting to water and soil upon spillage, as opposed to kerosene [8]. In addition, biodiesels do not contain trace metals, carcinogens like polyaromatic hydrocarbons, and other pollutants that are directly detrimental to human health [9].…”

Performance Evaluation of a Small-Scale Turbojet Engine Running on Palm Oil Biodiesel Blends

2014

The experimental and simulated performance of an Armfield CM4 turbojet engine was investigated for palm oil methyl ester biodiesel (PME) and its blends with conventional Jet A-1 fuel. The volumetric blends of PME with Jet A-1 are 20, 50, 70, and 100% (B20, B50, B70, and B100). Fuel heating values (FHV) of each fuel mixture were obtained by calorimetric analysis. The experimental tests included performance tests for Jet A-1 and B20, while the performances of B50 to B100 were simulated using GasTurb 11 analytical software. In terms of maximum measured thrust, Jet A-1 yielded the highest value of 216 N, decreasing by 0.77%, 4%, 8%, and 12% with B20, B50, B70, and B100. It was found that B20 produced comparable results compared to the benchmark Jet A-1 tests, particularly with thrust and thermal efficiency. Slight performance penalties occurred due to the lower energy content of the biodiesel blends. The efficiency of the combustor improved with the addition of biodiesel while the other component efficiencies remained collectively consistent. This research shows that, at least for larger gas turbines, PME is suitable for use as an additive to Jet A-1 within 50% blends.
