Biodiesel from different mixtures of animal fat and soybean oil has been synthesized, its properties have evaluated related to composition. A mixture 50 vol % both raw materials selected as a suitable feedstock for industrial biodiesel production, computer simulation the production process using Aspen Plus software carried out evaluate feasibility this scheme cheaper feedstock. The results obtained suggest that proposed described produces with acceptable by standards lower final cost....
Babassu and camelina oils have been transesterified with methanol by the classical homogeneous basic catalysis method good yields. The babassu fatty acid methyl ester (FAME) has subjected to fractional distillation at vacuum, low boiling point fraction blended two types of fossil kerosene, a straight-run atmospheric cut (hydrotreated) commercial Jet-A1. FAME kerosene without previous distillation. blends biokerosene Jet-A1 met some specifications selected for study ASTM D1655 standard: smoke...
The production and use of terpene-based fuels represents a renewable source energy in the transportation sector, especially aviation sector. literature on conversion terpenes into valuable compounds is not new but has been based products for cosmetics pharmaceutics. Several established chemical routes are also way to develop drop-in fuels. present work explores all main processes that can transform more or additives, focusing heterogeneous catalysis, catalyst type, operating conditions,...
With the aim to evaluate biodiesel performance and emissions of a feedstock with promising economic sustainability perspectives, such as waste animal fat, two fuels, one obtained from 100% fat other 50% soybean oil/50% were tested in DI common-rail diesel engine. Blends [30 70% (v/v)] these fuels reference fuel also tested. The pressure drop across filter was measured, for pure fuel, large increase over 5 h recorded, indicating clogged filter. This poor filterability should be considered by...
The use of biofuels in the aviation sector has economic and environmental benefits. Among options for production renewable jet fuels, hydroprocessed esters fatty acids (HEFA) have received predominant attention comparison with acid methyl (FAME), which are not approved as additives fuels. However, presence oxygen tends to reduce soot emissions therefore particulate matter emissions. This sooting tendency is quantified this work an oxygen-extended index, based on smoke point measurements....
The need to find sustainable alternatives fossil fuels in aviation without requiring drastic structural changes turbines and tanks has prompted a search for new components blend with the standard Jet A1. Turpentine obtained by vacuum distillation of resin extracted from common pine Pinus pinaster or as byproduct paper industry is compared hydrogenated turpentine at different levels conversion component jet blends. Properties such density, kinematic viscosity, heating values, lubricity, flash...
Orange oil was extracted by steam distillation from the peels of oranges produced as waste in orange juice factories. This raw oil, a potential source for biojet fuel, analysed FT-IR and GC-MS, compared with distilled pure d-limonene, which is its main chemical constituent. Both d-limonene were hydrogenated under reaction conditions (from 3 to 18 bar) are mild enough be industrially feasible, improve properties, especially reduce their sooting tendency. Some important properties such...
Wine industry generates a large amount of biowaste, such as grape marc and wine lees, which is considered in the Directive (EU) 2018/2001 an adequate feedstock to produce advanced biofuels. Grapeseed oil fatty acid ethyl esters (FAEEs) can be obtained from extracted bioethanol distilled lees or surplus. Although FAEE still has no specific standard, grapeseed would fulfill all properties set by standard EN 14214, except oxidation stability. This work analyzes effect natural antioxidants on...
Many concerns, such as economic and technical viability social ethical aspects, must be considered for a feedstock selection advanced biofuels. Industrialized countries promote the use of industrial waste or by-products this purpose. In particular, turpentine has several properties which make it an attractive source biofuels, including its possible origin. Nevertheless, shown some disadvantages when blended directly with diesel, especially because increases sooting tendency. On contrary,...
