20110232171 | METHOD OF MAKING A REFORMATE - A device and method for producing a reformate fuel from a hydrocarbon gas source. The invention enables the conversion of a dilute hydrocarbon gas into a more easily consumable reformate fuel.

The reformate is more easily consumed by an energy conversion device such as a combustion engine, fuel cell, sterling engine or similar device that converts chemical energy into kinetic or electrical energy. The reformer enables complex hydrocarbon fuels that are not normally suitable for use in an energy conversion device to be converted into a reformate. The reformate may be directly supplied into the energy conversion device. | 09-29-2011 |

20120017496 | HYDROPROCESSING PROCESS WITH IMPROVED CATALYST ACTIVITY - This invention relates to a hydroprocessing process with improved catalyst activity when hydroprocessing petroleum based feedstock or an oxygen containing feedstock. This invention also relates to a hydrotreating process with improved hydrodesulfurization (HDS) activity of a hydrotreating catalyst such as Co/Mo by co-feeding carbon monoxide or its precursors. Such inventive process confirms that adding a small amount of CO to H2 in a hydrotreater for a few days leads to an increase in product sulfur due to the inhibition of CO on the hydrotreating catalyst such as Co/Mo. However, it has been unexpectedly found that after the CO was removed from the hydrogen stream, product sulfur levels decreased to values below they were before CO addition which means the activity of the hydrotreating catalyst increased after the CO treatment. | 01-26-2012 |
20120266529 | Fast pyrolysis system - A fast pyrolysis system includes an auger housing having an inlet, an outlet, and an inner wall. A rotatable auger is mounted in the housing. The auger has surfaces defining at least one spiral channel. The spiral channel is tapered from a first depth adjacent the housing inlet to a second lesser depth adjacent the housing outlet. The auger is rotatable to propel particulate materials from the housing inlet toward the housing outlet to heat the particulate material to a first temperature sufficient to convert at least a portion of the particulate material into a vapor. A heat exchanger transfers a heat of vaporization from a heated medium to the auger housing inner wall. A filter assembly is connected downstream to the housing outlet in order to filter char fines from the vapor. A condenser is connected downstream to the filter assembly and is adapted to condense the vapor stream into bio-oil. | 10-25-2012 |
20150075063 | METHOD AND SYSTEM FOR OXIDATIVELY INCREASING CETANE NUMBER OF HYDROCARBON FUEL - High energy (e.g., ultrasonic) mixing of a hydrocarbon feedstock and reactants comprised of an oxidation source, acid, and optional catalyst yields a liquid hydrocarbon product having increased cetane number. Ultrasonic mixing creates cavitation, which involves formation and violent collapse of micron-sized bubbles, which greatly increases reactivity of the reactants. Cavitation substantially increases cetane number compared to reactions carried out using conventional mixing processes, such as simple mechanical stifling. An aqueous mixture comprising water and acid can be pretreated with ozone or other oxidizer using ultrasonic cavitation prior to reacting the pretreated mixture with a hydrocarbon feedstock to promote cetane-increasing reactions. Controlling temperature inside the reactor promotes beneficial cetane-increasing reactions while minimizing formation of water-soluble sulfones. | 03-19-2015 |
