ASTM D6296-98(2008) 用多维气相色谱法测定火花点火发动机燃料中总烯烃的标准试验方法

The quantitative determination of olefins in spark-ignition engine fuels is required to comply with government regulations. Knowledge of the total olefin content provides a means to monitor the efficiency of catalytic cracking processes. This test method provides better precision for olefin content than Test Method D 1319. It also provides data in a much shorter time, approximately 20 min following calibration, and maximizes automation to reduce operator labor. This test method is not applicable to M85 or E85 fuels, which contain 85 % methanol and ethanol, respectively.1.1 This test method provides for the quantitative determination of total olefins in the C4 to C10 range in spark-ignition engine fuels or related hydrocarbon streams, such as naphthas and cracked naphthas. Olefin concentrations in the range from 0.2 to 5.0 liquid-volume % or mass %, or both, can be determined directly on the as-received sample whereas olefins in samples containing higher concentrations are determined after appropriate sample dilution prior to analysis. 1.2 This test method is applicable to samples containing alcohols and ethers; however, samples containing greater than 15 % alcohol must be diluted. Samples containing greater than 5.0 % ether must also be diluted to the 5.0 % or less level, prior to analysis. When ethyl-tert-butylether is present, only olefins in the C4 to C9 range can be determined. 1.3 This test method can not be used to determine individual olefin components. 1.4 This test method can not be used to determine olefins having higher carbon numbers than C10. Note 18212;Precision was determined only on samples containing MTBE and ethanol. 1.5 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

1.1 This test method covers the quantitative determination of total sulfur in gasoline and gasoline-oxygenate blends. The Pooled Limit of Quantitation (PLOQ) was determined to be 15 mg/kg. Therefore, the practical range for this test method is from 15 to 940 mg/kg. Note 1-This concentration range is based on that used in the interlaboratory round robin as reported in Research Report , which shows that the range of sulfur in the round robin samples was from 1.5 to 940 mg/kg; however, below 15 mg/kg, the reproducibility approaches 100% of the concentration. 1.2 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. For specific hazard information, see Note 2. 1.3 The values stated in SI units are to be regarded as the standard. The preferred units are mg/kg sulfur.

ASTM D6293-98 用气相色谱对低烯烃火花点火引擎燃料芳香碳氢化合物类型,环烃,烯烃,石蜡和氧化物的标准试验方法

1.1 This test method provides for the quantitative determination of oxygenates, paraffins, olefins, naphthenes, and aromatics in low-olefin spark-ignition engine fuels by multi-dimensional gas chromatography. Each hydrocarbon type can be reported either by carbon number (Note 1) or as a total through C10, except for olefins, which can only be reported through C9. Higher boiling hydrocarbons cannot be reported by type and are reported as a composite group. The lower limit of detection for a single hydrocarbon component or carbon number type is 0.05 mass %. Note 1-There can be an overlap between the C9 and C10 aromatics; however, the total is accurate. Isopropyl benzene is resolved from the C8 aromatics and is included with the other C9 aromatics. Naphthalene is determined with the C11 components. 1.2 This test method is applicable for total olefins in the range from 0.05 to 13 mass %. The test method can quantitatively determine olefins in samples where the olefin concentration does not exceed 0.6% C4 or 4.0% C5 or 4.5% of the combined C4 and C5. Although the precision for benzene was determined in the range from 0.3 to 1.0 mass %, this test method can be used to determine benzene concentrations up to 5.0 mass %. 1.3 This test method is not intended to determine individual hydrocarbon components except for those hydrocarbon types for which there is only one component within a carbon number. Individually determined hydrocarbons are benzene, toluene, cyclopentane, propane, propylene, and cyclopentene. 1.4 Precision data has only been obtained on samples containing MTBE. Application of this test method to determine other oxygenates shall be verified in the user's laboratory. Methanol cannot be determined and shall be quantitated by an appropriate oxygenate method such as Test Method D 4815 or D 5599. Methanol is fully resolved and does not interfere with the dertermination of other components or groups. 1.5 Although specifically written for spark-ignition engine fuels containing oxygenates, this test method can also be applied to other hydrocarbon streams having similar boiling ranges, such as naphthas and reformates. 1.6 The values stated in SI units are to be regarded as the standard. 1.7 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

1.1 This test method provides for the determination of individual volatile sulfur-containing compounds in gaseous fuels by gas chromatography (GC) with flame photometric detection (FPD). The detection range for sulfur compounds is from 20 to 20 000 picograms (pg) of sulfur. This is equivalent to 0.02 to 20 mg/m3 or 0.014 to 14 ppmv of sulfur based upon the analysis fo a 1-mL sample. 1.2 This test method describes a GC-FPD method using a specific capillary GC column. Other GC-FPD methods, with differences in GC column and equipment setup and operation, may be used as alternative methods for sulfur compound analysis with different range and precision, provided that appropriate separation of the sulfur compounds of interest can be achieved. 1.3 This test method does not intend to identify all individual sulfur species. Total sulfur content of samples can be estimated from the total of the individual compounds determined. Unknown compounds are calculated as monosulfur-containing compounds. 1.4 The values stated in SI units are to be regarded as standard. The values stated in inch-pound units are for information only. 1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
