The present invention enables a party to receive a renewable fuel credit for the transportation or heating fuel.

Methods and Apparatus for Recovery of Volatile and Carbonaceous Components from Unconventional Feeds

A device to extract water and volatile organic compounds from asteroids, comets, and other space resources for propellant production, life support consumables, and manufacturing from in-situ resources in support of advanced space exploration is described. The device thermally extracts ice and water bound to clay minerals, which is then combined with small amounts of oxygen to gasify organic matter contained in carbonaceous chondrite asteroids.

HYDROGEN PRODUCTION PROCESS

Process and method to generate hydrogen with high CO.sub.2 capture rate. The invention entails production of hydrogen in an efficient and innovative way without any continuous carbon emissions within the hydrogen production unit by use of only one CO.sub.2 removal unit.

Process for producing synthesis gas

A process for producing hydrocarbons is disclosed in which a first feed substream and a second feed substream are obtained from a hydrocarbonaceous feed stream, of which the first feed substream is converted by means of partial oxidation or autothermal reforming to a first synthesis gas stream and the second feed substream is converted by means of steam reforming to a second synthesis gas stream and subsequently combined with the first synthesis gas stream to give a third synthesis gas stream, of which at least a first portion is converted by Fischer-Tropsch synthesis to a crude product stream comprising hydrocarbons of different chain lengths, from which light hydrocarbons are separated in a tail gas, in order to recycle them and use them in the partial oxidation or autothermal reforming. The characteristic feature here is that unsaturated hydrocarbons are separated from at least a portion of the tail gas.

Vent line for use in ammonia and hydrogen plants

In an ammonia or hydrogen plant comprising a desulfurisation section, a reforming section and a shift section, where the shift section comprises a low temperature shift converter and a medium temperature shift converter, a vent line is arranged downstream from the low temperature shift converter and the medium temperature shift converter in order to allow the shift converters to be re-heated with process gas at a low pressure (typically 3-7 bar). This way condensation of water vapour in the process gas is avoided. By applying this vent line it becomes possible to save significant time, more specifically 8-24 hours, for restarting the production after temporary shut-down thereof, because a heat-up of the LTS/MTS converter in circulating nitrogen is avoided.
