Abstract:
A process for the conversion of synthesis gas to liquid hydrocarbon products by contacting the synthesis gas at an elevated temperature and pressure with a suspension comprising catalyst suspended in a liquid medium, in a system comprising a high shear mixing zone and a tubular loop reactor said process comprising the steps of:a) passing the suspension comprising catalyst suspended in the liquid medium through the high shear mixing zone where synthesis gas is mixed with the suspension; b) discharging a mixture comprising synthesis gas and suspension from the high shear mixing zone into the tubular loop reactor; c) converting at least a portion of the synthesis gas to liquid hydrocarbon products in the tubular loop reactor to form a product suspension comprising catalyst suspended in the liquid medium and the liquid hydrocarbon products; d) separating a gaseous stream comprising unconverted synthesis gas from the product suspension; e) recycling the separated gaseous stream to the high shear mixing zone; and f) recycling at least a portion of the product suspension to the high shear mixing zone.
