| Energy-related sectors in IO table and energy statistical yearbook | Energy sectors in hybrid LCI model | Allocation method of energy consumptions |
|
| Coal mining and dressing | 1-1 Raw coal
1-2 Cleaned coal
1-3 Other washed coal | Ratio of energy consumptions of raw coal (1-1) and washed coal (1-2, 1-3) was assumed to be 25 : 9, based on Grade 3 of clean production standard of coal mining and processing industry [24] |
|
| Petroleum and natural gas extraction | 1-8 Crude oil
1-16 Natural gas | Crude oil and refinery gas are consumed in Crude oil extraction. Natural gas is consumed in natural gas extraction |
|
| Petroleum processing, coking, and processing of nuclear fuel | 1-4 Coke
1-5 Coke oven gas
1-6 Other gases
1-7 Other coking products
1-9 Gasoline
1-10 Kerosene
1-11 Diesel oil
1-12 Fuel oil
1-13 Liquefied petroleum gas
1-14 Refinery gas
1-15 Other petroleum products | Coking products are consumed in coking. Crude oil and refinery gas are consumed in processing of petroleum. Ratios of refining efficiency of gasoline, kerosene, diesel, liquefied petroleum gas, and fuel oil are assumed to be 85% : 87% : 89% : 93.5% : 95% [25]. Refining efficiency of refinery and other petroleum are assumed to be the same as fuel oil |
