TLDR
In this article, a fuel composition with a high flash point and a high octane number is provided, which is useful as emergency fuel for use in gasoline-powered vehicles and can be mixed with an additive of alcohols, ethers, esters, or organometallic compounds or mixtures thereof.Abstract:
A fuel composition with a high flash point and a
high octane number is provided. The preferred
embodiment of the fuel comprises a paraffin or
aromatic hydrocarbon component which may be mixed
with an additive of alcohols, ethers, esters,
organometallic compounds or mixtures thereof. The
fuel composition is useful as emergency fuel for use
in gasoline powered vehicles.read more

Compositions for control of induction system deposits
TL;DR: In this paper, fuel additive compositions are described comprising of at least one fuel-soluble detergent/dispersant which is (a) a fuel solver, amide, imide, oxazoline and/or ester, or a mixture thereof, of a long chain aliphatic hydrocarbon-substituted dicarboxylic acid or its anhydride.

Process for the gasolines production
TL;DR: In this article, a process for the production of high octane and low benzene content gasolines according to a cycle where a crude oil is fed into an atmospheric distillation unit from which a fraction is obtained called virgin naphtha sent in turn to a splitting unit that produces a fraction called light tops and a fraction which has a six carbon atoms (C6) hydrocarbons content no greater than 0.5 % volume.
Patent
Blended gasolines and process and apparatus for making same
TL;DR: In this paper, a mixture of a natural gasoline component and at least one octane-enhancing component is used to produce a desired octane rating, an environmentally acceptable vapor pressure, and a mix which, when burnt in an internal combustion engine, produces a minimum amount of pollutants.
