Calorific value
the amount of heat or energy generated by a specified quantity of a fuel source

a common non-metallic element, occurring naturally as diamond, charcoal and graphite. One of the most important elements for the development of life, and the storage of energy.

Carbon chain
the atomic structure of hydrocarbons in which a series of carbon atoms, saturated by hydrogen atoms, form a chain. Volatile oils have shorter chains. Fats have longer chain lengths, and waxes have extremely long chains.

Carbon cycle
The continuous process of combining and releasing carbon and oxygen thereby storing and emitting heat and energy. Catabolism + anabolism = metabolism.

Carboxyl Carboxylic
the uni-valent acid radical (-COOH), present in most organic acids, this making them bio-degradable.

a substance which without itself undergoing any permanent chemical change, facilitates or enables a reaction between other substances.

Combined Heat and Power. A phrase used to suggest greater efficiency obtained when the waste heat from generating electricity can be used locally to provide low temperature heat for processing or domestic heating.

a reaction in which a substance produces heat or light by combination with oxygen, producing an oxide.

Diesel Engine Road Vehicle, but also used to describe the original form of mineral fuel used as a substitute for organic oils burned in compression ignition engines designed by Diesel.

non-volatile mineral fuel with a high flash point used in compression ignition engines, as invented by Dr Rudolf Diesel in 1895, originally running on peanut oil. The name of the inventor was then transferred by the petrochemical industry to the fossil fuel that became the substitute for the organic oils for which this form of engine was originally…

Energy of activation
the amount of energy required as heat or pressure to disbalance an otherwise stable but energy storing compound so that it will release its potential energy. The energy that must be overcome to allow an otherwise exothermic reaction to proceed.

a measure of the unavailability of the thermal energy within a system for conversion into mechanical work All energy transformations (i.e. chemical to chemical, chemical to thermal) increase entropy.

an organic proteinaceous compound that catalyses a specific biochemical reaction.

a classification of organic compounds occurring naturally as oils and fats, produced by replacing the hydrogen of an acid by an alkyl, aryl, radical. A compound of an organic acid bonded via an ester bond to an alcohol.

Production of ester by reacting alcohol and carboxylic acid

C2H6O An organic alcohol also called ethyl alcohol, formed when fermenting sugars or glycerin

Fatty Acid Methyl Ester.

a classification of natural esters of glycerol, and fatty acids existing as solids at room temperature.

remains of organic materials, subsequently buried within the earth`s crust, often carbonized as a result of intense heat and / or pressure.

liberated. In the case of triglycerides, meaning the fatty acid hydrocarbon chains are detached from glycerol, and thereby become free fatty acids.

Glycerin Glycerol
C3H8O3, a sweet greasy organic substance, produced as a result of hydrolysing triglycerides.

oily or fatty matter, normally of organic origin, consisting of hydrocarbon chains. (American term).

a compound of hydrogen and carbon, often occurring as long atomic chains in which each carbon atom is attached to two hydrogen atoms forming a long chain. They store a great deal of energy.

H The lightest gaseous element, and simplest of all atoms, occurring rarely in nature as a single atom, but common in the form of water, and in all organic compounds

a substance which changes colour at a given stage in or as a result of a chemical reaction.

Dodecane (Kerosene) C12H26 commonly used mineral fuel oil used as aviation fuel and central heating consisting of many hydrocarbons containing molecules with about 10 to 16 carbon atoms.

Life-cycle analysis
a total valuation of a process, in which all the inputs and outcomes of a reaction are fully considered.

a classification of organic compounds, including fatty acids, oils, waxes and steroids, that are insoluble in water but soluble in organic solvents.

CH3OH A volatile colourless alcohol, derived originally as wood alcohol, used as a racing fuel and as a solvent. Also called methyl alcohol.
