A weighed sample is burned in an oxygen bomb calorimeter under controlled conditions. The introduction to each chapter defines the fuels being discussed, in- dicates the analyses covered and the preferred method of analysisand gives other supplemental information about the fuel that may be of in- terest in any environmental assessment of processes using the fuel.

Nitrogen in shale oil naphtha fraction is present as pyridines, pyrroles, and nitriles. D Ash, wt. Standard sampling methods for shale oil and coal liquids have not been developed, but the procedures given in ASTM D”Standard Method of Sampling Petroleum and Petroleum Products”1, will give a significant amount of guidance. Sample boats may have to be modified to hold liquid sample.

For coal and coke: An ultimate analysis includes moisture, carbon, hydrogen, nitrogen, sulfur, ash, and oxygen by difference. It is designed specifically for use with aviation turbine fuels when the per- missible difference between duplicate determinations is of the order of 0.

RDSF may be used as the sole fuel in a heat-generating process, or it may be used as a supplementary fuel. ASTM D describes the ‘. Not appli- cable to LPG, gasoline, or lubricating oils con- taining additives. Should be applicable for SO and CL. Should be appli- cable to RDSF. The time required for a 60 ml sample to flow through a cal- ibrated orifice is measured under carefully controlled conditions.


The catalysts used in making methyl fuel are quite sensitive to contamination by sulfur, and its concentration is accordingly reduced to low levels, often 0.

The publication discusses several shale oil analyses including water, distillation, nitrogen, sulfur, specific gravity, pour point, and viscosity. Some vari- ability of the methods used for the nitrogen and sulfur qstm had to be accepted because one or more of the laboratories did not perform the specified methods.

Con- densed solvent and water are continuously separated In a trap, the water settling in the graduated section of the trap and measured volumetri- cally. The nature of the coke formed depends upon the original coal and the carbonization process employed.

The net calorific value may be calculated from the gross calorific value, as described in ASTM D l. A sample is dissolved in a suitable liquid and titrated with Karl Fisher reagent, which is a mixture of iodine, sulfur dioxide, pyridine, and methanol or glycol ether. This is an indirect method, dependent upon the weight loss of the sample. Modifications are d1154 scribed for high residue mate- rials.

How- ever, this technique is dependent upon the availability and use of reference standard gas mixtures for empirical calibration of quantitative and qualita- tive i.

Personal communication from Thomas Lamb, Arthur D. Thus, sample sizes may need to be increased in some cases and appropriate adjustments made in the analytical procedure. The criteria for the selection of methods to be included in this manual, and for the selection of “preferred” meth- i ods, are given in the following subsection.

Such materials are prepared, tested, and certified by experts in their fields. ASTM D also covers specifications for sample containers, sample han- dling, labeling, and shipping. Contents of the Manual 3 4. For others excluding suspensions: Will not be adequate for finely milled peat. P Unknown for MF. The chlorine content of the sample is determined at the same time as sulfur.


This transfer was in accordance with ASTM’s plans to phase-out non-metric methods of test for petroleum products.

Coal Liquids C. Applicable to crude petro- leum, tars, and products derived from these mater- ials. All of these properties vary with water content, and.

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. Method developed for coal and coke. Measurement of the calorific value and density of isolated i. Generally applicable to petroleum products that are not highly volatile and that contain at least 0. At the end of a 30 minute heating per- iod the crucible is cooled and weighed.

Liquid Fuels A listing of reference’ materials available for liquid fuels is given in Table A Apparent Density NA A significant amount of work has been done to determine the hydrocarbon types including N- and S- compounds in shale oils and procedures for shale oil characterization have been worked out.

As shown in the listing, a botanical standard for trace ele- ments and nitrogen should be a reasonably close match for the cellulosic fuels, peat and RDSF, in lieu of materials specific to those fuels. It should be noted that none of the listed methods were developed for specific applicability to shale oil and coal liquids.
