Scope

GB/T 37178-2018 is the English-translated version of 车用煤制合成天然气.

GB/T 37178-2018 specifies the coal-based synthetic natural gas used as a fuel for vehicles. It sets the terms and definitions, technical requirements, test methods, sampling and test rules, and conditions for storage and use.

Methane, hydrogen, oxygen, carbon monoxide, carbon dioxide and ammonia are measured according to GB/T 33445, total sulfur according to GB/T 33318, water dew point according to GB/T 17283 and solid particles according to GB/T 27893, which also serve as arbitration methods.

Sampling follows GB/T 13609 and must take account of hydrogen embrittlement. It applies to such gas at a pressure of not more than 25 MPa, including hydrogen-rich gas separated from it, but not to vehicle natural gas made from natural gas. It was issued on 28 December 2018 and has applied since 1 July 2019.

1 Scope

This Standard specifies the terms and definitions, technical requirements, test methods, sampling and test rules, storage and use of coal-based synthetic natural gas for vehicle.

This Standard is applicable to coal-based synthetic natural gas whose pressure is not more than 25 MPa and which is used as fuel for vehicles, including hydrogen-rich gas which is separated from synthetic natural gas, and excluding natural gas for vehicle which uses natural gas as raw material.

5 Test method

5.1 Determination of methane, hydrogen, oxygen, carbon monoxide, carbon dioxide and ammonia components in coal-based synthetic natural gas shall be carried out in accordance with GB/T 33445. Other equivalent methods may be used to determine methane, hydrogen, oxygen, carbon monoxide, carbon dioxide and ammonia components in coal-based synthetic natural gas for vehicle, and the arbitration test method is GB/T 33445.

5.2 Determination of total sulfur content in coal-based synthetic natural gas shall be carried out in accordance with GB/T 33318. Other equivalent methods may be used to determine the total sulfur content in coal-based synthetic natural gas for vehicle, and the arbitration test method is GB/T 33318.

5.3 Determination of water dew point of coal-based synthetic natural gas shall be carried out in accordance with GB/T 17283. Other equivalent methods may be used to determine the water dew point of coal-based synthetic natural gas for vehicle, and the arbitration test method is GB/T 17283.

5.4 Determination of the total content of solid particles in coal-based synthetic natural gas for vehicle shall be carried out in accordance with GB/T 27893. Other equivalent methods may be used to determine the total content of solid particles in coal-based synthetic natural gas for vehicle; and when the measurement result is objectionable, the arbitration test method is GB/T 27893. The test is carried out after decompression by a decompression device that has no filter.

6 Sampling and test rules

6.1 Sampling

The sampling of coal-based synthetic natural gas for vehicle shall be carried out according to GB/T 13609; the influence of hydrogen embrittlement shall be fully considered, and the sampling container shall be carefully selected.

6.2 Test rules

6.2.1 All items in Table 1 of Chapter 4 are delivery test items.

6.2.2 Under the following circumstances, coal-based synthetic natural gas products shall be thoroughly tested in accordance with the technical requirements in this Standard:

-- When it is first put into production;

-- In normal production, after regular or cumulative production; […]
