PRO 2000-CALORIC will also clean tanks, lines, vaporizing equipment, and burner nozzles of sludge, waxes, oils and water or other liquids. Regular use will continue this cleaning action preventing future buildups.

PRO 2000-CALORIC treated propane releases heat at an average of 9% faster than regular untreated propane. An additional benefit is a 50F. to 100F. degree higher flame temperature resulting in more efficient economical operation of equipment and lower emissions. This translates into less fuel consumption to complete identical tasks. PRO 2000-CALORIC provides the marketer with a premium propane to differentiate his product from competitors and the end user with a more cost effective way to complete his many projects using the fuel.

PRO 2000-CALORIC can be injected into any size storage vessel prior to filling for immediate mixing. No settling will occur at the recommended dosage of one gallon PRO 2000- CALORIC to three thousand gallons of propane. DANGER: Harmful or fatal if swallowed. Wash with soap and water if exposed to the skin. Keep out of the reach of children.

RE: Studies of the effect of Bell's new PRO 2000-Caloric with Catalyst on the rate of heat release from commercial mixtures of LPG.

At your request, Bell Additives' chemist has been conducting studies in his laboratory on the effect of various catalysts on the rate of heat release in the combustion of LPG. These studies are performed in an adiabatic reactor and the total amount of heat released is measured as a function of time. By using this technique he can measure the effect that a catalyst has on the speed of the combustion process. He has performed tests on pure propane and various mixtures of propane with other C-3 and C-4 molecules. The mixture that we told him we were most interested in is one that approximates a commercial mixture that is sold in South America. The mixture that he made up and tested in his laboratory consisted of the following on a volume (i.e. molar) percent basis: 55% propane, 10% propylene, 20% butane, 10% i-butane, and 5% mixture of cis and trans-2- butanes.

He has tested a large number of catalyst samples that he has formulated in his laboratory along with several commercial catalysts that are available on the open market.

The new PRO 2000- Caloric with Catalyst formula gave the greatest increase in heat release for all of the combustion catalysts that he has tested thus far.

When the fuel mixture described above was tested at a volumetric treat ratio of 1 part additive to 3000 parts fuel, the rate of heat release was measured to increase by an average of 9% plus or minus 2%. This average was generated from ten separate experimental runs.

The chemist indicated that his testing in mixtures with a high percentage of propane and with pure propane showed even better improvement in the speed of heat release when treated with the PRO 2000-Caloric with Catalyst.
