    Abstract: This disclosure discusses integrating syngas streams with refinery hydrotreators, synthetic hydrocarbon gas to liquid (GTL) processes, and power generation units (such as combined cycle units) to efficiently use hydrogen contained in the syngas produced from heavy hydrocarbons (pet coke, residues, oil, etc.). Membrane separation and pressure swing adsorption is used to separate components of syngas and feed them to refineries, GTL units, and power/steam generation units. Hydrogen-rich refinery purge is used to raise the H2/CO ratio of syngas. A hydrogen-enriched syngas is produced with an H2/CO ratio favorable for the production on synthetic hydrocarbons (greater than about 1.5 to about 2.0 or higher). Pure hydrogen is also produced in a PSA unit, to further raise the H2/CO ratio of the syngas and provide hydrogen feed for refinery hydrotreators and synthetic hydrocarbon units (such as methanol units).

The blending process is optimized to meet coke quality requirements and simultaneously to obtain a pyrolysis gas composition suitable for production of ancillary products including liquid transportation fuels, fertilizer, hydrogen, and electricity. By using lower cost Indiana/Illinois Basin coal it is possible to reduce net coal costs.

Energy released in some of these processes is used by other processes.

  • Publication number: 20100041776
    Abstract: A technique of cooling of a reactor with a fixed catalytic bed for exothermic catalytic syntheses, such as the Fischer-Tropsch (FT) synthesis of liquid fuels by selective hydrogenation of the monoxide of carbon (CO) by the hydrogen (H2), includes mixing of these two gases being called “synthesis gas” or “syngas”, and is characterized by the fact that the heat of such synthesis is taken away by a heat medium of non-fossil origin and having a high boiling point in comparison with water and that at least a part of the resultant vapors of such boiling heat medium is extracted from the reactor to feed, as a carbonaceous matter, another reactor, called “reformer”, in which this vapor is converted into syngas to feed the aforesaid reactor of exothermic synthesis.

  • Patent number: 7642292
    Abstract: A process and system for producing hydrocarbon compounds or fuels that recycle products of hydrocarbon compound combustion—carbon dioxide or carbon monoxide, or both, and water. The energy for recycling is electricity derived from preferably not fossil based fuels, like from nuclear fuels or from renewable energy. The process comprises electrolyzing water, and then using hydrogen to reduce externally supplied carbon dioxide to carbon monoxide, then using so produced carbon monoxide together with any externally supplied carbon monoxide and hydrogen in Fischer-Tropsch reactors, with upstream upgrading to desired specification fuels—for example, gasoline, jet fuel, kerosene, diesel fuel, and others. Energy released in some of these processes is used by other processes. Using adiabatic temperature changes and isothermal pressure changes for gas processing and separation, large amounts of required energy are internally recycled using electric and heat distribution lines.

    Abstract: A process is provided to make ethylene and propylene from a carbonaceous feedstock. The process comprises preparing a gaseous mixture of carbon monoxide and hydrogen from a feedstock. A Fischer Tropsch synthesis is then performed on the gaseous mixture to obtain a Fischer Tropsch product along with unconverted carbon monoxide and hydrogen. The Fischer Tropsch product in admixture with the unconverted carbon monoxide and hydrogen from the previous step is then subjected to terminal cracking to form ethylene and propylene.
