“…As noted earlier, a distillation curve test results in a curve that represents the percentage of recovered volume versus boiling temperature. Due to the importance of a distillation curve shape and its implication for engine performance, distillation curve is a valuable metric measurement of the overall volatility and driveability of a fuel [97]. Elevated final boiling points indicate long combustion times, incomplete combustion of heavy hydrocarbons that leads to deposits and smoke formation increment, and poor atomization of the fuel/air mixture, which causes a diminution in the engine power and an increment in the fuel consumption [98].…”

The liquids resulting from pyrolysis of industrial plastic waste (IPW) and post-consumer colour and white plastic film waste (PCPW and PWPW, respectively) at pilot scale (80 kg/h) were widely 2 characterized by different techniques in order to assess their potential as both petrochemical raw material and automotive diesel fuel. It was found that pyrolysis liquids mainly consisted of hydrocarbons in the diesel boiling point range (180-380 ºC), amounting to approximately 50-55 % (in vol.). Therefore, the results were further contrasted with limits established by EN 590:2014 + A1:2017 standard for automotive diesel fuel. Although pyrolysis liquids showed good properties, they do not conform with some key fuel parameters for diesel engines, such as density, distillation curve, kinematic viscosity, flash point and cold filter plugging point. In order to improve these properties, PWPW pyrolysis liquids were distilled in the diesel range and the liquid fractions were characterized according to automotive diesel standards. It was found that the diesel fraction met all specifications with the exception of cold filter plugging point (-10 ºC to 4 ºC vs. -10 ºC winter/0 ºC summer) and density (800-807 kg/m 3 vs. 820 kg/m 3 ). To accomplish with standards, a blend of diesel obtained from PWPW pyrolysis liquids and commercial diesel (50/50 wt. %) was also prepared and analysed. Results revealed that the blend met the requirements of the 21 parameters demanded by the standard for a product to be marketed and used as automotive fuel in diesel engine vehicles.

Optimization of Bio-Hydrogenated Kerosene from Refined Palm Oil by Catalytic Hydrocracking

In this work, hydro-processing was used as an alternative route for producing bio-hydrogenated kerosene (BHK) from refined bleached deodorized palm oil (RPO) in the presence of a 0.5 wt% Pd/Al2O3 catalyst. The Box-Behnken Design was used to determine the effects of reaction temperature, H2 pressure, and reaction time in terms of liquid hourly space velocity (LHSV) on BHK production. The kerosene selectivity was used as the response for staticial interpretation. The results show that both temperature and LHSV produced significant effects, whereas H2 pressure did not. The optimal conditions were found to be 483 °C, 5.0 MPa, and 1.4 h−1 LHSV; these conditions provided approximately 57.30% kerosene selectivity and a 47.46% yield. The BHK product had a good heating value and flash point. However, the mass percentage of carbon and hydrogen was 99.1%, which is just below the minimum standard (99.5%), according to the carbon loss by the reaction pathway to form as CO and CO2. Water can be produced from the reaction induced by oxygen removal, which results in a high freezing point.

Fuel-Lubricant Interactions: Critical Review of Recent Work

A critical review of recent work on fuel lubricant interactions is undertaken. The work focusses on liquid fuels used in diesel and gasoline vehicles. The amount of fuel that contaminates the lubricant depends on driving conditions, engine design, fuel type and lubricant type. When fuel contaminates a lubricant, the viscosity of the lubricant will change (it will usually decrease), the sump oil level may increase, there may be a tendency for more sludge formation, there may be an impact on friction and wear, and low speed pre-ignition could occur. The increased use of biofuels (particularly biodiesel) may require a reduction in oil drain intervals, and fuel borne additives could contaminate the lubricant. The move to active regeneration of particulate filters by delayed fuel post-injection and the move to hybrid electric vehicles, and vehicles equipped with stop-start systems will lead to increased fuel dilution. This will be of more concern in diesel engines, since significant fuel dilution could still persist at sump oil temperatures in the range 100-150C (whereas in gasoline engines the more volatile gasoline fuel will have substantially evaporated at these temperatures). It is anticipated that more research into fuel lubricant interactions, particularly for diesel engines, will be needed in the near future.
