20080242749 | Process For the Removal of Cos From a Synthesis Gas Stream Comprising H2S and Cos - The invention provides a process for the removal of COS from a first synthesis gas stream comprising COS and H | 10-02-2008 |
20080275144 | Method to Start a Process for Producing Hydrocarbons from Synthesis Gas - Method to start a steady state process for producing normally gaseous, normally liquid and optionally normally solid hydrocarbons from synthesis gas, which process comprises the steps of: (i) providing the synthesis gas; and (ii) catalytically converting the synthesis gas at an elevated temperature and a steady state total reactor pressure to obtain the normally gaseous, normally liquid and optionally normally solid hydrocarbons; the method comprising admixing the synthesis gas of step (i) with one or more inert gases to form an admixture stream prior to catalytically converting the synthesis gas in step (ii) at the steady state total reactor pressure and wherein as the activity of the catalyst converting the synthesis gas proceeds towards a steady state, the amount of inert gas(es) in the admixture stream is reduced. | 11-06-2008 |
20080306171 | Method to Start a Process for Producing Hydrocarbons from Synthesis Gas - Method to start a steady state process for producing normally gaseous, normally liquid and optionally normally solid hydrocarbons from synthesis gas, which process comprises the steps of: (i) providing the synthesis gas; (ii) catalytically converting the synthesis gas in one or more conversion reactors at an elevated temperature and a pressure to obtain the normally gaseous, normally liquid and optionally normally solid hydrocarbons; and (iii) using at least a portion of the gaseous hydrocarbons produced by step (ii) as a recycle stream to be reintroduced into conversion reactor(s) of step (ii); the method comprising admixing a hydrogen stream with the recycle stream of step (iii) prior to its reintroduction into conversion reactor(s) of step (ii), wherein as the activity of the catalyst converting the synthesis gas proceeds towards a steady state, the amount of recycle stream is reduced. | 12-11-2008 |
20090101346 | In situ recovery from a hydrocarbon containing formation - An oil shale formation may be treated using an in situ thermal process. Heat may be applied to the formation to raise a temperature of a portion of the formation to a pyrolysis temperature. Heat input into the formation may be controlled to raise the temperature of portion at a selected rate during pyrolysis of hydrocarbons within the formation. A mixture of hydrocarbons, H | 04-23-2009 |
