Disclosed are methods for transporting one or more synthetic products produced from a carbonaceous source, such as coal, natural gas, or biomass, which may be located in a location that is remote from markets for such products. The synthetic products may include lower molecular weight alcohols such as methanol, lower molecular weight ethers such as dimethyl ether, olefins and/or the products of a Fischer-Tropsch or other hydrocarbon synthesis. The methods include transport of such synthetic products via a pipeline in the dense phase state, either neat or blended with light hydrocarbons, such as natural gas.
