Vapor　Compositions　and　Flammability　Limits　of　Methano1／Naphtha　Blend　Fuels

Abstract

The　vapor　compositions　of　methanol／naphtha　blend　fuels（M85，M90，M95）have　been　calculated　in　terms　of　UNIFAC equation．The　vapor　di伽sion　has　been　treated　using　an1－dimensional　modeL　Based　on　the　estimated　flammability　limits in　air，the　explosion　hazard　of　M85 and　M90 fuels　is　found　to　be　around　the　same　as　naphtha　mder　ordinary　temperature conditions．
