Definitions

  • the present invention relates to a binder which is suitable for the production of briquettes, to the use of this binder for the production of briquettes and to briquettes that are produced by using this binder.
  • a coal briquette on the one hand, should be able to gently glow under conditions where relatively little combustibles and oxygen are present, whereas under other conditions the briquette should be able to burn with a clear flame and not fall apart unburned. This may be expressed as fuel efficiency in terms of the coal content of the ashes.
  • Another aspect of the burning behaviour is that a good fuel efficiency is required.
  • the former aspect of the burning behaviour can also be viewed as a mechanical requirement for the binder, i.e. the binder should be able to confer to the briquette during burning enough strength that it will not fall apart until used up for the greater part.
  • the (national) criteria regarding the the emission of environmentally objectionable substances should be met.
  • the selection of the binder is also determined by the sulfur content, the ash content and the emission of compounds during combustion or other processing.
  • Smell is a criterion which is more subjective than the above-mentioned criteria. It has been found, for example, that the acceptance of coal briquettes for domestic use largely depends on the extent to which the binder and the briquette give off an undesirable smell under storage or usage conditions. Strongly smelling briquettes generally are not accepted. This is, of course, related to the fact that the briquettes are often stored in storage spaces which often are badly ventilated, such as in basements, and in the proximity of food such as potatoes or other personal effects.
  • GB-A-960 921 does not disclose the use of components obtained from the steam cracking of light hydrocarbons.
  • the binder which is suitable for the production of briquettes or shaped forms, comprises
  • One preferred way to modify the polyaromatic pyrolysis oil is to substantially remove the low molecular fraction from the oil to obtain a pyrolysis oil fraction with a more narrow molecular weight distribution which improves the adhesive strenght and affinity with respect to the fines that are to be briquetted.
  • this concerns reducing the fraction having a molecular weight (determined by GPC in THF) smaller than 1000, so that a product remains having a ring and ball softening point of at least 100°C, preferably 110-170°C.
  • the binder is preferably substantially free of ashes, minerals, metals and in particular free of elements of the group IIIA and VA of the Periodic System of Elements, or compounds thereof.
  • substantially free is meant that the content of the respective component is not higher than 0.05% by weight, based on the binder.
  • the binder according to the invention has an excellent homogeneity and stability. More particularly, the binder fulfils the requirements of Dutch standard NEN 3965, which means, among other things, that no phase separation takes place during storage.
  • This product was mixed at 175°C with 15% by weight (based on the total binder) of a mixture (1/1) of vacuum residue and vacuum distillate.
