WebMethane is assigned a Methane Number of 100 and pure Hydrogen is assigned a Methane Number of zero. A natural gas having a Methane Number of 80 for example, would have the detonation properties of a mixture consisting of 80 vol% Methane and 20 vol% Hydrogen. The Methane Number concept is similar to the Octane Number for gasoline.

Web1 mrt. 2005 · RON Index =3.205+ (0.279*EXP (0.031*RON)) where RON is the volume percentage of the component in the blend.Calculate the RON indices of all the components (of course,knowing their RON) and find the volume average RON Index. Then invert the above function on the volume average RON index to get the RON of the blend.Simple!:) WebAnswer (1 of 8): * First of all, KNOCKING is phenomena that occurs in an S.I. engine in which combustion of some air-fuel mixture takes not as a result of propagation of flame front but outside it. * It is a fuel characteristic so the fuels have knock rating and to determine this, finding OCTAN... WebOctane numbers. Octane numbers of low-molecular mass alcohols are high, and therefore they have been even used as octane boosters. Alcohols tend to increase the research octane number (RON) more than the motor octane number (MON). The blending RON of ethanol is about 120-135, and the blending MON 100-106. tim woessner attorney
