Equations were developed for the estimation of gross heat of combustion (HG) of triglycerides (TGs) and fatty acid methyl esters (FAMEs) from their saponification number (SN) and iodine value (IV). HG of TG=1,896,000/SN − 0.6 IV — 1600 and HG of FAME=618,000/SN − 0.08 IV — 430. When these equations were tested on cottonseed oil, soybean oil, partially hydrogenated soybean oil, peanut oil, sunflower oil, sunflower oil methyl esters, soybean oil methyl esters and cottonseed oil methyl esters… 
Prediction of higher heating values for saturated fatty acids from their physical properties
Abstract Higher heating values (HHVs) of fatty acids (C 4 –C 18 ) were measured and correlated using linear least square regression analysis. Equations were developed for the estimation of the HHVs
Higher heating value (HHV) of vegetable oils, fats and biodiesels evaluation based on their pure fatty acids' HHV
Higher heating value (HHV) is an important property of a fuel, especially for vegetable oils, fats and their derivatives which are intended to replace petroleum fuels. There are lots of methods to
Survey of seed oils for use as diesel fuels
Fifty-one out of 364 plant seeds being surveyed had fatty acid contents greater than 15% (dry weight), and their methyl esters had cetane indices higher than 50. Rambutan seed was an exception, with
Predicting cetane number, kinematic viscosity, density and higher heating value of biodiesel from its fatty acid methyl ester composition
Abstract Biodiesel is a renewable bio-fuel derived from natural fats or vegetable oils, and it is considered as a promising alternative to substitute diesel fuels. Cetane number, viscosity, density,
Synthesis of fatty acid methyl ester from rice bran oil
TLDR
In the present study, biodiesel has been prepared from Rice Bran oil by transesterification method, and will play a vital role to meet the diesel requirement in India.
Prediction of Higher Heating Values for Biodiesels from Their Physical Properties
Abstract Higher heating values (HHVs) of vegetable oils and their biodiesels were measured and correlated using linear least square regression analysis. Equations were developed for the calculation
Seed oils from non-conventional sources in north-east India: potential feedstock for production of biodiesel
TLDR
If prepared from these oils, biodiesels are likely to meet the major specification of biodiesel standards of the USA, Germany and European Standard Organisation.
Estimation of Density of Biodiesel
Density of biodiesel is an important physical property of liquid fuel and biodiesel. A slight change in density can affect engine output power. In this work, density of a saturated, unsaturated fatty
Relationships derived from physical properties of vegetable oil and biodiesel fuels
Abstract The aim of this study was to estimate mathematical relationships between higher heating value (HHV) and viscosity, density or flash point measurements of various biodiesel fuels. The HHV is
In Situ Trans-Esterification of Residual Oils in Spent Bleaching Clays from Vegetable Oil Refineries
Spent bleaching clays (SBCs) from vegetable oil refineries are industrial wastes. The clays contain large amount of oils (20-25%), which are good feedstock for biodiesels. Non-thermal in situ

Heats of combustion of fatty esters and triglycerides
Gross heats of combustion (HG) have been measured for three classes of fatty esters and two classes of triglycerides (TGs). The esters included saturated methyl esters, Me 6:0–22:0; saturated ethyl
Chemical and physical properties of vegetable oil esters and their effect on diesel fuel performance

Methyl and ethyl soybean esters as renewable fuels for diesel engines
The primary problems associated with using straight soybean oil as a fuel in a compression ignition internal combustion engine are caused by high fuel viscosity. Transesterification of soybean oil
The effects of vegetable oil properties on injection and combustion in two different diesel engines
