Abstract
A composition useful as a fuel additive or as a fuel blend component, said composition including: aliphatic diesters: esters of aromatic monomers; and esters of short aromatic oligomers. Also disclosed are processes to make fuel additives and fuel blend component compositions.
Claims20
A composition useful as a fuel additive, said composition comprising:
- aliphatic diesters:
- esters of aromatic monomers;
- and
- esters of short aromatic oligomers.
- The composition according to claim 1, wherein said aliphatic diesters are selected from the group consisting of:
- malonate diesters, succinate diesters;
- and maleate diesters.

1 more element
A process for the preparation of a fuel blend component, said process comprising the steps of:
- providing a light fraction of an esterified lignin-hemicellulose depolymerized organics (esterified LHDO) composition:
- wherein said light fraction of esterified LHDO composition is isolated via hexane or iso-octane extraction:
- wherein said light fraction of esterified LHDO composition comprises:
- aliphatic diesters;
- aromatic monomers;
- and oligomeric condensed aromatics;
- , admixing said light fraction of esterified LHDO composition with a hydrocarbon selected from the group consisting of:
- toluene and alkanes (preferably, C7-C10), more preferably, C6-alkane;
- C7-alkane;
- C8-alkane;
- purifying the said light fraction of esterified LHDO composition by adding an adsorbent material to the admixture at room temperature and mixing for a period of time sufficient to allow for the adsorption of minerals and insoluble organic compounds to yield a substantially aromatics-free composition,
- wherein said substantially aromatics-free composition comprises at least 90 by wt. % of aliphatic diester compounds comprising:
- malonate diesters, succinate diesters;
- and maleate diesters.
