Abstract
Petroleum products such as gasoline, diesel fuel, kerosene, heavy oil and others are co-products from crude oil, which mean that petroleum products cannot be produced independently, due to dependence on refinery configurations. In order to make the petroleum refining model, it is important to appropriately set the properties of the blendstocks from refinery units and blending ratios of these stocks for making products. In this report, petroleum refining model newly constructed for combining with existing Japanese MARKAL energy model will be described. A feature of this model is relatively simple by setting the blending ratios of blendstocks directly and is possible to appropriately express the co-product behavior.
