Abstract

Disclosed is a fuel additive concentrate having a high flash point which is characterized by a viscosity controlled for dosing in a Bernoulli feed device. The concentrate is high temperature stable and is in a form suitable for on-board dosing of fuel which can provide predictable feed rates from a feed device. It comprises a fuel soluble platinum group metal composition and/or a fuel soluble or dispersible cerium composition and/or a fuel soluble or dispersible iron compound and a high flash aromatic solvent. The solvent and the metal composition or compositions are present in relative amounts to provide a FBC concentrate having a flash point (ASTM D93-85) of greater than 140° F. and, a preferred kinematic viscosity within the range of from 7 to 25 centistokes, as measured by ASTM D445 at 105° F.

Claims

1. A high-temperature stable fuel borne catalyst concentrate in a form suitable for on-board dosing of fuel which can provide predictable feed rates from a feed device, and comprises:

a fuel soluble platinum group metal composition and/or a fuel soluble or dispersible cerium composition and/or a fuel soluble or dispersible iron compound; and

a high flash aromatic solvent;

wherein the solvent and the metal composition or compositions are present in relative amounts to provide a FBC concentrate having a flash point of greater than 140°

F.

2. A high-temperature stable fuel borne catalyst according to claim 1, wherein the kinematic viscosity is within the range of from 7 to 25 centistokes, as measured by ASTM D445 at 105°

F.

3. A high-temperature stable fuel borne catalyst according to claim 1, which comprises a fuel soluble platinum group metal composition and a cerium composition

4. A high-temperature stable fuel borne catalyst according to claim 1, wherein the platinum group metal composition comprises platinum acetyl acetonate and/or 1,5-cyclooctadiene platinum diphenyl and a cerium composition

5. A process for feeding a fuel borne catalyst into a fuel, comprising:

providing a concentrate as in claim 1 and feeding it into a capillary tube in communication with a fuel flow line.
