Abstract:
An additive composition for improving the cold flow properties of crude oils or fuel oils such as middle distillate fuel oils comprises an addition product or condensate cold flow improver additive in combination with a demulsifier.
Abstract:
The present invention relates to fuel additive compositions and additised fuels. In particular, the invention relates to additives for kerosene used in domestic oil-fired boilers. The fuel additive compositions of the invention include a dispersant; a demulsifier; a metal deactivator; and an antioxidant. Together these ingredients bring a range of instantaneous benefits, including enhanced fuel performance, reduced deposits, improved fuel economy/fuel consumption and reduced emissions.
Abstract:
A method of inhibiting or retarding formation of hydrates from water and a lower alkane, such as methane or ethane, involves adding additives which comprise (i) a corrosion inhibitor and (ii) a salt which is of formula [R (R )XR ] Y , wherein each of R , R and R is bonded directly to X, each of R and R , which may be the same or different is an alkyl group of at least 4 carbons, X is S, NR or PR , wherein each of R and R which may be the same or different represents hydrogen or an organic group, with the proviso that at least one of R and R is an organic group of at least 4 carbons, and Y is an anion, the additives being added in an amount effective to inhibit or retard hydrate formation, to a medium susceptible to hydrate formation.
Abstract:
Additives which improve the low-temperature properties of distillate fuels are the oligomeric and/or polymeric reaction products of aromatic anhydrides and epoxides (or their corresponding acid or diol equivalents) and the oligomeric and/or polymeric post-reaction products of amines and alcohols.
Abstract:
The invention relates to a method of burning a combustable substrate, incendiary compositions for use in the method and incendiary intermediates that can be used for making the compositions as well as being useable as incendiary compositions in their own right. The method comprises applying to the substrate an extrudible or granular incendiary composition having a temperature of combustion of at least the combustion point of the substrate, the composition comprising particulate metal, the metal being magnesium, calcium, or aluminium and an oxidizing agent capable of supporting combustion of the metal, dispersed in an inert extrudible carrier or a solid carrier. The invention is particularly useful for burning of pollutants for example oil spills and other substrates especially where sustained combustion is to be maintained.
Abstract:
Provided herein is a diesel fuel additive composition comprising cerium oxide nanoparticles, optionally a manganese compound, a detergent, and a demulsifier. In one embodiment, the demulsifier has relatively low phosphorus concentration to thereby improve the solubility of the components and the thermal stability and clarity of the resulting diesel fuel. Also provided are methods for improving fuel economy, reducing smoke production, inhibiting deposition of sludge, and improving storage stability.

Abstract:
Additives which improve the low-temperature properties of distillate fuels are oligomeric/polymeric reaction products of anhydrides and long-chain epoxides (or their corresponding acid/diol equivalents) consisting of hydroxyl promoted polyesters and ester promoted polyesters.
