Back Ground Information

We produce an high octane liquid fuel which is used as a gasoline additive or a straight fuel on its own. It is easily blended with either gasoline or diesel. With the pressure of crude oil shortage in storage, alcohol and bio-diesel have gained more attention in different countries. Corn or other 'grown' products are the feedstock that dominates the current ethanol market. Almost all of the ethanol produced and marketed in the United States and Canada is made from the fermentation of corn or other grown products essentially in the same manner that distiller¡¯s spirits are produced. These plants are large fixed facilities and specifically designed for the processing of corn, although other grains can be employed. But they are limited to using only the feedstock¡¯s mentioned.

Conversely, Vista's System process will convert virtually any source, which contains "free" carbonaceous material i.e. "almost everything": farm animal waste, municipal solid waste, biomass, natural gas, coal, coal fines, coal bed methane, flare gas from a refinery or a well, or sour gas wells that are high in sulfur, which our technology can process. None of these waste feedstocks are economically employed in the fermentation processes used to make fuels today. Corn ethanol plants may have similar capital costs per annual production gallon, but operating costs of Vista's Energy System are significantly lower since the feedstock comes from waste, which is not grown thus no additional feed stock costs are incurred. Furthermore, our feedstock costs are minimal; because the material is hydro-carbon based waste material. There is no other known catalytic process available in the world capable of converting carbonaceous sources into high octane liquid fuel at the conversion rate achieved by Vista. All other known technologies in the alternative energy arena require higher capital and operating costs, have ¡°lower¡± production yields, and many require subsequent refining to produce alcohol.

The Fischer-Trope (F-T) process, designed originally by Germany during WWII to fuel military vehicles, will convert natural gas or methane into a crude product requiring additional refining to produce alcohol fuels. The F-T process produces primarily diesel fuels. The F-T process also requires a clean, sulfur-free synthesis or natural gas feedstock and cannot convert other carbonaceous materials into ethanol. In this process, the feedstock is restricted to natural gas, the cost is higher and the yield is far lower than achieved by Vista's Energy System. Cobalt catalysts have proven to be poisoned by even microscopic amounts of sulfur in the natural gas feedstock. Our patented catalyst can withstand dirty synthesis gas and hydrogen sulfide with far greater output or production yields.

The dumping of municipal waste in traditional landfills is not only undesirable but in many metropolitan areas, a problem of crisis proportions. The production of methane gas from municipal and farm waste is a serious contributor to the global greenhouse effect and the landfill seepage and run-off contamination of ground water in many areas of the world is well documented. Converting waste to power with direct waste combustion (incineration) can eliminate waste in volume, but causes hidden danger for the atmosphere because poisonous elements from the waste can not be totally eliminated during the combustion due to the limited combustion temperature. In addition, the water from the waste before the combustion causes water pollution even though water treatment is applied because the water pollution standard is lower in most developing countries comparing to that of the developed countries. Water pollution from the incinerators has become a challenge for many governments. Our system will convert this waste into an environmentally clean, high-octane marketable motor fuel and eliminate water contamination and air pollution.
The high octane liquid fuel production system can be located near feedstock sources throughout the country. The distributed location of these plants will answer the primary need to expand current fuel production.
Feedstock sources for high octane liquid fuel production£º
Refuse Derived Fuel (RDF) from municipal solid waste or construction debris, landfill gas. Wood waste from forests related to current paper and plywood processing.
Coal reserves and coal waste from existing extraction methods. Coal bed methane gas. Agricultural products such as switch-grass or bamboo are grown for the purpose of producing synthesis gas.
Agricultural waste streams such as sugar cane bagasse, rice hulls, corn stover, cotton gin and olive or cherry pits. Anaerobic digestion or gasification of dairy and hog manure.
Methane gas from agricultural and food processing waste. Stranded natural gas that is isolated from pipeline sources.
Our technology will convert low purity synthesis gases now produced from Refuse Derived Fuel (RDF) and other Biomass material into a high purity, clean burning, mixed fuel. For this application, larger fixed-base systems will be designed and constructed individually.
