“…21 Mt/a in Europe, with production ca. 7.7 Mt/a in 2008 [27]) is currently significantly larger than the production of green diesel (0.34 Mt/a [28]), i.e. the product of hydrotreating of triglycerides.…”

“…The stand-alone processing of triglycerides into dieselfuel-range hydrocarbons allows enhancing the fuel quality as the primary green diesel has poor cold flow properties [28] and cannot be therefore used directly in diesel fuel blending, but in low blending concentrations. It has been demonstrated that cold-flow-properties additives are inefficient at as low concentration of n-alkanes (obtained by triglyceride hydrotreating) in diesel fuel as 5% [28].…”

Catalytic deoxygenation of triglycerides and related feedstocks for production of biofuels is reviewed in this paper. Green diesel, triglyceride-based hydrocarbons in diesel boiling range, is an attractive alternative to biodiesel-a product of transesterification of vegetable oils, particularly due to its superior fuel properties and full compatibility with current diesel fuels. Two basic approaches to production of green diesel-(i) hydrodeoxygenation of triglycerides and related compounds over metal sulfide catalysts and (ii) deoxygenation over supported noble metal catalysts are thoroughly discussed from the point of view of reaction conditions, catalyst composition and reaction pathways and products. Furthermore, catalytic cracking of triglycerides and related feedstocks over microporous and mesoporous catalysts is reviewed as well. It constitutes an interesting alternative to deoxygenation using hydrotreating and noble metal catalysts as it does not consume hydrogen. It provides a wide spectrum of products reaching from olefins to green gasoline and diesel.

The purpose of this research are to study the temperature influence in hydrocracking process of the nyamplung oil (Calophyllum inophyllum) using a non-sulfided CoMo/γ-Al2O3 catalyst and to develop a simple kinetic model in interpreting the data of hydrocracking products. The experiment was carried out in a pressurized batch reactor operated pressure up 30 bar. The CoMo catalyst supported with γ-Al2O3 was prepared through impregnation method without sulfidation process. The operating temperature varied from 200 to 350 o C. The results show that the non-sulfided CoMo/γ-Al2O3 catalysts, nyamplung oil triglycerides can converted into gasoil and gasoline-like hydrocarbons. The triglyceride hydrocracking reaction of nyamplung oil followed a several stages, i.e., hydrogenation, dehydrogenation, and cracking. Based on the compounds contained in liquid product, hydrocracking reaction was dominated by decarboxylation. The products obtained in hydrocracking process of nyamplung oil are classified to gasoil (C11-C18) and gasoline (C5-C10). The triglycerides hydrocracking reaction of nyamplung oil was assumed by following a series reaction mechanism and a simple kinetic model used for determined the kinetics constants. The highest reaction conversion is 99.10% obtained at temperature of 350 °C for 160 minutes reaction time.

“…Literature shows that green diesel used in blends with petrol diesel in a diesel engine reduces emissions of unburned hydrocarbons 2 Journal of Combustion and carbon monoxide [5]. The main disadvantage of green diesel is that the high concentration of n-paraffins in the final fuel downgrades the cold properties of the fuel [10]. Although literature highlights considerable research activity on performance and emissions of many types of engines fuelled with biodiesel from different feedstock, most of the results have been obtained with engine designed for agricultural purpose, tested in specific values of engine speed and load conditions.…”

The purpose of this paper is to conduct an experimental research on the impact of mixing ratio of biodiesel from waste cooking oil and an innovative diesel fuel (in which a renewable component is contained) on the emissions of an up-to-date light and compact small engine that has a leading role in city cars and urban vehicles. Two blends' mixing ratios (20% and 40% by volume) were tested and the results were compared to those obtained when the engine was operated with low sulfur diesel (ULSD) and ULSD blended with 15% by volume of renewable diesel. The results indicate that diesel+ enhances CO and HC emissions in the exhaust as regards ULSD. Blending diesel+ with WCO causes a further reduction for most of the engine operative field. Concerning particulate emission, accumulation mode dominates for all fuels. Diesel+ is always characterized by lower mean diameters as regards ULSD. The addition of WCO further reduces the court mean diameter. Particle number concentration obtained by fuelling the engine with B40 is the lowest as regards all the other tested fuels. Concerning NO , a moderate increase of the emission was observed when fuelling the engine with diesel+, net or in blends.
