Abstract:
Disclosed is a MMT containing motor fuel additive composition which synergistically combines the octane enhancing capabilities of MMT with the benefits of a special additive package to reduce both fuel intake system deposit formation and combustion chamber deposit formation, thereby reducing engine ORI and maintaining desired engine performance.
Abstract:
The present invention discloses a process for enhancing quality of a hydrocarbon stream. More particularly, the present invention discloses a process for improvement of the combustion quality of a diesel range stream by dissolving an oxygen source in the feed stream before carrying out the oxidation, thereby enhancing the Cetane number, lubricity and reducing emission of the stream. The present invention also discloses a process for enhancing combustion quality of a hydrocarbon stream by carrying out the process in presence of an organometallic catalyst.

Fuel compositions comprising a major amount of a normally liquid hydrocarbon based fuel and a minor amount of a compound having at least one strained ring group containing from 3 to 4 ring atoms.
Abstract:
The proposed method of producing a homogeneous catalyst for fuels involves adding acetone or homologues of acetone to the fuel and enriching the fuel with carbonyl compounds, in particular glyoxal or polyglyoxal, by oxidation with O3 or O2/O3 mixtures. Enrichment takes place preferably in the presence of heterogeneous catalysts with oxidising properties. The heterogeneous catalysts which can be used are the metals iron, manganese, copper, cerium, molybdenum, tungsten, vanadium, bismuth, titanium, rhodium, platinum and palladium, or their oxides, sulphides, phosphates or mixtures. The application also concerns a fuel containing a homogeneous catalyst produced by this method.
Abstract:
High energy (e.g., ultrasonic) mixing of a liquid hydrocarbon feedstock and reactants comprised of an oxidation source, catalyst and acid yields a diesel fuel product or additive having substantially increased cetane number. Ultrasonic mixing creates cavitation, which involves the formation and violent collapse of micron-sized bubbles, which greatly increases the reactivity of the reactants. This, in turn, substantially increases the cetane number compared to reactions carried out using conventional mixing processes, such as simple mechanical stirring. Alternatively, an aqueous mixture comprising water and acid can be pretreated with an oxidation source such as ozone and subjected to ultrasonic cavitation prior to reacting the pretreated mixture with a liquid hydrocarbon feedstock.
Abstract:
Disclosed is a fuel and/or crude oil additive comprising at least one ferric or ferrous formate and at least one solvent, dispersant, stabiliser, anti-caking agent and/or other auxiliary agent known in the art and optionally in addition thereto one or more additional organic or inorganic metal compounds. Said ferric or ferrous formate is suitably present in said additive in an amount of between 0.5 and 99.5% by weight.
