1、Designation:D754412Standard Specification forPyrolysis Liquid Biofuel1This standard is issued under the fixed designation D7544;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revision.A number in parentheses indicat
2、es the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope*1.1 This specification covers grades of pyrolysis liquidbiofuel produced from biomass intended for use in varioustypes of fuel-burning equipment under various climatic and
3、operating conditions.These grades are described as follows:1.1.1 Grade G is intended for use in industrial burnersequipped to handle the pyrolysis liquid biofuels meeting therequirements listed for Grade G in Table 1.The pyrolysis liquidbiofuel listed under Grade G in Table 1 is not intended for use
4、in residential heaters,small commercial boilers,engines,ormarine applications.1.1.2 Grade D is intended for use in commercial/industrialburners requiring lower solids and ash content and which areequipped to handle the pyrolysis liquid biofuels meeting therequirements listed for Grade D in Table 1.T
5、he pyrolysis liquidbiofuel listed under Grade D in Table 1 is not intended for usein residential heaters,engines,or marine applications notmodified to handle these types of fuels.NOTE1For information on the significance of the physical,chemical,and performance properties identified in this specifica
