Systematic observations of temperature and condensate volume are made, and the report- ed results calculated from these data.

Method specified by ASTM for testing of methyl alcohol. Sample is combusted in hydro- gen to hydrogen sulfide and measured by the methylene blue method.

Because of the varying need for standards, initial analysis of a completely unknown gaseous fuel should probably be done using mass spectrometry. Most of the methods described are already widely accepted for the analysis of petroleum fuels1. The time required for a 60 ml sample to flow through a cal- ibrated orifice is measured under carefully controlled conditions. In some cases, the product fuels may be hot and may still contain some amounts of sulfur compounds, higher hydro- carbons, and ammonia which have not been removed.

For some of the crude shale oils, over half of the material consists of compounds of sulfur, nitrogen, and oxygen, and less than half consists of pure hydrocarbons. The accuracy of these measurements is, for the most part, a func- tion of the accuracy with which the calibration standards have been made. Distillation is continued to the dry point and the temperature recorded. Personal communication from Mr.

D Ash, wt. Refuse-Derived Solid Fuels Refuse-derived solid fuels RDSF are taken here to primarily include pro- cessed municipal refuse; the processing may include magnetic separation, shredding, air classification, chemical treatment, milling or other such processes.

The chlo- rine compounds liberated are absorbed in a sodium carbonate solution and the amount of chlorine present determined gravimetrlcally by precipita- tion as silver chloride.

This is an extractive process in ast a petroleum-based donor liquid is placed in contact with coal under hydrogen pressure resulting in an ex- tracted coal oil. A sample is dissolved in a suitable liquid asm titrated with Karl Fisher reagent, which is a mixture of iodine, sulfur dioxide, pyridine, and methanol or glycol ether. This holds especially for the variability and high values of the moisture content and the resulting need to report all other analyses on a moisture-free basis.

Constituent identifica- tion and quantitative calibra- tion are accomplished by ana- lyzing reference standard gas mixtures under same conditions.

See Re- ference 1 for additional information. See Reference 11 for details. The sulflde is treated with acidified solu- tion of an aromatic amlne and ferric chloride catalyst to form methylene blue due which is measured by colorimetry.

An ultimate analysis includes moisture, carbon, hydrogen, nitrogen, sulfur, ash, and oxygen by difference.

Coke The methods for analyzing coke are essentially the same as asgm coal des- cribed in Table VI See Reference 1 for other points. This includes both crude and refined shale oil. The availability of the publication containing the method and the extent to which the method is currently used in laboratories con- ducting fuel analyses.

For 62, bituminous coal. Addi- tionally, no attempt was made to resolve, by laboratory tests, the nu- merous uncertainties concerning the applicability of specified methods to fuels other than those the method was originally intended for.

Applicable to fuel oils, lube oils, and other petro- leum liquids. Reproducibility; Ranges from 0. It is used widely as a fuel in Ireland and Russia. See Refer- ence fl for s1145 points. Shale Fuel Oil D.

Gasoline motor and aviation 3. Results are usually re- ported on an “as received” basis or on a “dry” basis. Coals are comprised of five major elements: The mass spectrum of the mixture is analyzed by com- parison with the spectra of in- dividual, pure components of the mixture. May be applicable to MF. The material is produced by subjecting raw municipal refuse to the following series of operations: May be appli- cable to MF.

A small flame is directed into the cup- through opening in the cover – at regular intervals with simul- taneous Interruption of the stir- ring. Since neither material is currently in commercial produc- tion, most sampling in the near term will be connected with bench or pilot scale research facilities. Environmental assessments of processes using RDSF will need to include additional fuel analyses beyond those covered in this manual.

Table VI-1 presents a summary of the analyses for coal with the preferred methods. With the use of suitable reference standards, it can give more quantita- tive information as well as provide further identification. The density is read from the hydrometer scale where it breaks the liquid surface.

Test temperature must be speci- fied by the parties concerned. Sul- fur contents are generally lower than in petroleum oils. For example, in dissolution of coal, pro- cesses might involve hydrogenation, catalysis, thermal liquefaction, and a host of other variables, singly or in combination. Column packing and length modified as necessary for particular mixture. The method is more time consuming than the bomb washing method. Their principal weakness may be that test sample sizes may be too small for RDSF that is not sufficiently homo- geneous resulting in erratic results on replicate samples.
