There are three types of product — solid, liquid and gas. Each type and a selection of examples is given below. For each individual product, there are three sets of data that can be provided as indicated under 1,2 and 3 below.

Gas LHV fuel gas, MHV fuel gas, SNG, hydrogen, ammonia,

Liquid Naphtha, diesel, gasoline, fuel oil, bio-oil, liquefaction oil, tar, methanol, ethanol, fuel alcohol, MTBE, ETBE, char-water slurry, char — oil slurry,

Solid Charcoal.

In addition chemicals might be included as a separate category as follows:

Chemicals Methanol, ethanol, ammonia, benzene, toluene, xylene, phenol, hydroxyacetaldehyde, acetic acid, and several hundred other specialities such as hydroxyacetaldehyde, levoglucosan etc.

a Physical and chemical properties

For each product, basic data on physical and chemical properties should be provided. This can range from simple to extensive according to resources available and might include:

• Higher heating value — MJ/kg,

• Lower heating value — MJ/kg,

• Elemental analysis — weight basis — CHONS etc. and minor and trace components,

• Molecular weight,

• Viscosity,

• Density,

• Solubility in water, hydrocarbons, other solvents,

• Flash point,

• Explosive limits,

• Toxicity,

• etc.

b Production methods

The sources by technology can be identified for each product and cross referenced to the TECHNOLOGY file.

c Production costs

It would be possible to derive simple relationships that express product cost as a function of plant size and feed cost. This could not be achieved in the current budget and time scale.
