Acidity due to HC1 is deducted.

It is necessary to correct for hydrogen originally present as moisture in the sample. A proximate analysis includes moisture, volatile matter, ash, and fixed carbon determined by difference for a coal sample.

A polished copper strip in im- mersed in a sample at a certain temperature for a time charac- adtm of the sample being tested. D11455 is combusted in hydro- gen to hydrogen sulfide and measured by the methylene blue method.

Liquefied petroleum gas 2.

The methods discussed are based on Bureau of Mines methods for petroleum11 with modifications included to take into account the apparent poor heat stability of shale oil and the presence of large quantities of olefins and nitrogen compounds. 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.

The peat container specified the contents to be “pure” Canadian Sphagnum Peat Moss. Analysis is by either the Kjeldahl-Gunning or an alter- native method.

P Varies with the initial boil- ing point and end point of the material and with the rate of change of thermometer readings. A chamber of the apparatus is filled with a chilled sample and connected to an air cham- ber at The predetermined temperature for the initial crude distillation is specified by the parties concerned in the evaluation; it is not specified in the method.


Method developed for nitro- gen containing organic com- pounds. What is implied is a recommenda- tion over the other available methods based on considerations of appli- t cability, precision and accuracy, availability of detailed instructions, and current or expected usage.

Frequently, the composition is described in terms of solubility in various solvents, such as hexane, pentane, pyridine, and benzene. Limit of method is.

Applicable to water and wastewater. The density is then read from the hydro- meter scale where it breaks the liquid surface. Generally -applicable to relatively nonvolatile petroleum products which partially decompose on distillation at atmos- pheric pressure. Applicable to mixtures of saturated and unsaturated hydrocarbons, and carbon monoxide. The lowest temperature at which movement of the oil is observed is the pour point. OZ P Repeatability; 0. Undergoing thermal decomposition, the light constituents of the coal are volatilized, and the heavier components crack, releasing hydrogen.

When more than one method is available, the preferred method is listed first. Should be applicable to SO -and CL. For coal, sum of weights should be with- in 21 of initial sample weight.

Elimination of traditional grouping was consciously planned to foster technology transfer and a maximum interface in related fields. The lowest temperature at which the vapors ignite is the flash d11145. Determined by difference from ultimate analysis.


The amount needed varies with the value of the parameter being mea- sured. See Refer- ence 01 for details. Waste lubricating oils may contain a variety of added components such as phosphorus, zinc, calcium, and barium. A sample is digested in a mix- ture of sulfuric acid, potas- sium sulfate and d115 ox- ide converting nitrogen to ammonium sulfate. When more preci- sion is required in the gross sample, the methods described in ASTM D”Standard Methods for Collection of a Gross Sample of Coal”1, may be applicable with only slight modification; Section 8 and Appendices A-l and A-2 of this method are especially pertinent.

Should be applicable for SO and CL. Should be applicable to MF.

Both shale oil and coal liquids. May be applicable to MF. 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. These are the sample requirements for a single analysis of asm or coke and may be significantly different from the amount of RDSF needed.

The time required for a 60 ml sample to flow through a cal- ibrated orifice is measured under carefully controlled conditions. The liberated compounds in the gaseous state are collected, condensed, and upgraded into a liquid pro- duct that is the rough equivalent of a crude oil.
