WebThe Fitch® Fuel Catalyst reformulates gasoline, diesel, fuel oil, propane and natural gas causing the reformulated fuels to produce more energy during combustion than these fuels otherwise would. It is a true catalyst which by definition causes one or more chemical reactions but does not participate in them. WebA catalyst is a substance which increases the rate of a reaction without being used up itself. They provide an alternative reaction route with a lower activation energy. Catalysts are split into two main types: heterogeneous and homogeneous. Autocatalysis is a reaction which can accelerate itself, as one of the products can catalyse the reaction. fluorite chakra

WebPlatinum helps to accelerate this reaction (acting as a catalyst) by binding with the H2 molecule. When the H2 molecule binds to the platinum surface the bond between the two H's in the H2 is weakened (so that each H can form a weak bond with the Pt surface). Platinum is so good at this that the H2 basically falls apart and forms 2 Pt-H bonds. fluor marine propulsion benefits loginWebCatalysts do not appear in the overall chemical equation for a reaction.
