CETALYST™ A - Catalyst

CETALYST™ A is an environmentally friendly and boiler safe catalyst designed to promote the oxidation of the carbon particulates that survives the combustion process. This carbon ends up contaminating the fly ash and is referred to as Loss on Ignition or LOI and is reported as a percentage of the fly ash. Disposal of carbon contaminated fly ash is costly as well as an environmental nightmare.

  • The carbon in the fly ash is wasted high energy fuel. Utilizing this fuel can provide a Heat Rate Improvement (HRI) or efficiency increase, and, in the case of bituminous coals, this can demonstrate a direct savings of 0.5-1.5% in fuel costs. Indirect savings associated with CETALYST™ A are also significant, 0.5%+, with reductions in coal transportation and handling, equipment maintenance, emissions hardware, and reactant costs.
  • The use of this catalyst also permits the reduction of excess combustion air. Excess air is used drive the oxidation process towards completion and minimize the formation of hazardous carbon monoxide, CO, in the flue gas. But pumping large volumes of air is expensive. Reducing excess air demonstrates a Heat Rate Improvement of 0.5-1.5%. An additional Heat Rate Improvement of 0.5% can be expected due to the decrease in stack sensible heat loss. It is important to note that there is a significant reduction in NOx formed during combustion that accompanies reduced excess air.
  • Incomplete combustion leads to carbon particulates in the ash. CETALYST™ provides “in-situ” coal ash beneficiation where the carbon is burned up in the furnace increasing efficiency and leaving the ash cleaner. This transforms the ash from an expensive liability to a valuable commodity for the concrete and rare earth metals extraction industries.

CETALYST™ B - Absorbent/Reactant

CETALYST™ B is an absorbent and reactant. It is a calcium-containing compound that forms porous, reactive cenospheres when added to the flue gas after the combustion process. These cenospheres react with or absorb SOx, NOx, mercury, and halogens effectively removing them from the flue gas stream.

CETALYST™ B pays for itself in two ways. First, it significantly reduces harmful emissions, NOx, SOx, mercury, and hydrogen chloride and second, it ends up in the fly ash which can be sold into the concrete industry.
