Abstract
A transportable Fischer-Tropsch syncrude product and a method for manufacturing and (transporting and/or receiving) the product is disclosed. The product has a true vapor pressure of less than about 15 psia, preferably less than 11 psia, when measured at its transportation temperature, and includes at least 60% by weight, preferably at least 75% by weight, of linear hydrocarbons. The method involves converting a light hydrocarbon feedstock into syngas, converting the syngas to products via Fischer-Tropsch synthesis, and isolating a plurality of transportable products from the Fischer-Tropsch synthesis. The products have true vapor pressures of less than about 15 psia, preferably less than about 11 psia, when measured at their transportation temperature. At least one of the transportable products has a pour point in excess of 20° C. At least two of the products are transported separately in liquid form. The products can be transported using any commonly used means of transportation, including marine tankers, rail cars, pipelines, trucks, barges and combinations thereof. Petroleum products can be blended with one or more of the transportable Fischer-Tropsch products, so long as the resulting blended composition has a true vapor pressure of less than about 15 psia, preferably less than 11 psia, when measured at its transportation temperature.
