As greater demands are put on the refineries to meet EPA standards,
fuel quality continues to change with the addition of more oxygenates
and other additives, the tendency of fuel to be affected by bacteria,
water and oxidation is increasing. Fuel is not perfect when refined
and once fuel leaves the refinery, it is subject to attack by oxygen
and microorganisms such as bacteria that grow in the fuel ingesting
fuel molecules and expelling non-standard molecules as by-products.
With the passage of time these processes of oxygen attack and microorganism
growth contribute to the increase in the concentration of non-conforming
molecules that are present in small quantities when fuel leaves
the refinery. These non-conforming molecules prevent engines from
performing at their optimum level and can prevent fuel delivery
systems from functioning. Extensive research devoted to our
area of expertise in hydrocarbon fuel reformulation bears directly
on this area of concern for high fuel quality. We would like to
share with you two recently completed evaluations. Test
1. Oxidation Stability ASTM D525 Paragon Labs in Michigan
performed an Oxidation Stability test (ASTM D525.4016 procedure
attached). This test provides an indication of the age of fuel and
the fuels ability to resist oxygen attack and formation of gums. The
attached test report. (FFC Test ASTM D525 2002) from Paragon Labs
was performed on a sample of New York fuel. This sample was near
the lower limits of acceptable for sale in the US (Minimum 240 minutes).
Portions of this fuel were subjected to the FFC for a 24-hour soak
and a seven-day soak. The results indicate that after 24 hours the
fuel was improved by 57% and after seven days there was a similar
finding. This indicates that the presence of the FFC not only prevents
premature oxidation but it is capable of restoring fuel to a higher
quality. These results are similar to those previously obtained
by APSI in a 1996 report from Auto Research Labs in Illinois (FFC
Test ASTM D5251996). Test 2. Influence of the Fitch Fuel
Catalyst on Bacterial Growth in Gasoline APSI has engaged
the Dept of Chemistry at the University
of Connecticut to perform a series of investigations into hydrocarbon
fuels. The investigation that is the subject of this report is one
in that series. We are enclosing a copy of this recently concluded
evaluation. The results of these studies show a significant reduction
in bacterial growth in gasoline that is attributable to the introduction
of the FFC into the fuel sample. Bacteria are a major cause of premature
aging of fuel and one of the reasons there are so many fuel additives
and cleaners on the market today. These reports are significant
and definite proof that the FFC will keep fuel fresh longer thereby
reducing the tendency of fuel to form varnishes and gums, which
damage fuel system components. With the integration of the Fitch
Fuel Catalyst into every machine manufactured, the fuel in the machine
will be of the highest possible standard and quality. The fuel insurance
that the Fitch Fuel Catalyst provides guarantees there will be fewer
fuel system problems and a better running engine.
Bacterial
Studies on the Effect of Fitch Fuel Catalyst in Gasoline
The University of Connecticut
has been engaged to perform certain investigations into hydrocarbon
fuels by Advanced Power Systems International Inc of Lime Rock Ct.
The investigation that is the subject of this report is one in a
series funded from grants by the United States Government, Department
of Defense. The DOD granted to APSI over $500,000 to investigate,
1: The viability of using the Fitch Fuel Catalyst technology as
a means to reduce fuel losses by preventing premature aging of stored
fuel. 2: The use of this improved fuel in reducing overall operating
costs predicated on superior combustion. This report describes work
done at UCONN under contract to APSI Inc. Dr. S. Suib and Dr. Claudia
P. Koerting of UCONN Principal Investigators. Dr. A. Berlin head
of Research and Development for APSI supervised this work. The work
performed in this report was performed between November 2001 and
May of 2002. Purpose of the Investigation Rationale and
Justification In this investigation the researchers endeavored
to construct an experiment that would measure the effect the presence
of Fitch Fuel Catalyst (FFC) has on a bacteria known to degrade
or breakdown fuels. Bacteriology The objective
of the bacteriological studies on the FFC was to determine the antimicrobial
effect of the FFC on bacterial growth in fuel. To prepare for this
study a literature search was performed for bacteria that can grow
using fuel, especially gasoline, as food. Both single and mixed
cultures were considered for study. The factors considered in the
search of an optimum bacterial strain included the following: (i)
Easy availability (ii) Easy growing conditions (iii)
Detectable results within a short course of time, and (iv)
Biosafety level 1 (non-pathogenic) (v) Commonly used as a
model fuel-biodegrader The literature spans over 30 years
of study of microorganisms, which can consume fuel.
Conclusion
Bacteria growth in the presence of 2% gasoline increased until
the addition of the FFC, day 10. Viable counts declined post FFC
addition. (Figure 1, 2) It is clear that there is a suppression
of growth of bacteria in the sample with the FFC present with respect
to the sample where the FFC was not present. Note: Details
