Background technology
The fuel such as liquefied gas, natural gas, kerosene, coal tar, heavy oil, diesel oil, gasoline and coal belong to fossil energy, and alcohol-group fuel and biodiesel belong to non-fossil energy.Non-fossil energy is also referred to as biomass energy.Alcohol-group fuel is the environmental protection energy, and the most fully and completely, thermal conversion efficiency is the highest, discharges based on water and carbon dioxide in burning, is the most clean, most environmental protection in future, has the fuel of development potentiality most.Alcohol-group fuel is the fuel of main body configuration exactly with alcohols (as methyl alcohol, ethanol, propyl alcohol, butanols, amylalcohol, hexanol etc.) material.From 2008, the advantage of alcohol-group fuel caused attention in the industry, but its technical difficulty is large, synthesize the fuel compared favourably with gasoline, diesel oil, also need more advanced technical research and practice.
Bio-fuel methyl alcohol: be exactly the most simply methyl alcohol in alcohol-group fuel, it is a kind of colourless, transparent, inflammable, volatile toxic liquid, to metal non-corrosiveness (except lead, aluminium) under normal temperature, slightly alcohol smell.Molecular weight 32.04, relative density 0.792 (20/4 DEG C), fusing point-97.8 DEG C, boiling point 64.5 DEG C, combustion heat 725.76KJ/mol, flash-point 12.22 DEG C, self-ignition point 463.89 DEG C, vapour density 1.11, vapour pressure 13.33KPa (100mmHg, 21.2 DEG C), steam and air mixture explosion limit 6.0 ~ 36.5% (volume ratio), energy and water, ethanol, ether, benzene, ketone, halogenated hydrocarbons and other organic solvents many miscible, but it is not miscible with benzinum, heat, naked light or oxidant easy firing, volatile, transport dangerous, volatilization also can make object painted surface be corroded in way.
Bio-fuel ethanol: fairly simple in alcohol-group fuel is ethanol, and it is achromaticity and clarification liquid.There are calcination taste, easily flowing, very easily from air, absorb moisture, can dissolve each other with arbitrary proportion with water and the multiple organic solvent such as chloroform, ether, azeotropic mixture (moisture 4.43%) can be formed with water, azeotropic point 78.15 DEG C, relative density 0.789 (20/4 DEG C), fusing point-114.1 DEG C, boiling point 78.5 DEG C, index of refraction (n20d) 1.361, during closed-cup, flash-point 13 DEG C, inflammable, and steam and air can form explosive mixture, explosion limit 3.5 ~ 18.0% (volume).
ISE, also claims membrane electrode, is that a class utilizes membrane potential to measure the activity of effects of ion or the electrochemical sensor of concentration.Its principle is by effects such as the diffusion of some ion in film both sides, migration and ion-exchanges, optionally produce membrane potential to certain ion, and the relation of membrane potential and this ionic activity meets Nernst equation.This kind of electrode due to have selective good, equilibration time is short, is potentiometry indicator electrode with the most use.According to the difference of film character, be divided into again amorphous film electrode, crystal film electrode, sensitization electrode etc.
