The present invention addresses to a process for the integrated production of H.sub.2 and aviation kerosene from renewable raw materials aiming at reducing CO.sub.2 emissions and consequently bringing benefits to reduce the impact of global warming on the planet. The process involves a hydrotreatment section to obtain n-paraffins followed by a hydroisomerization section to produce isoparaffins. The water and light hydrocarbons obtained in the isoparaffin production process are used for the production of H.sub.2 by the steam reforming process. An alcohol, such as ethanol or glycerin, with less than 6 carbon atoms, is fed into the hydrotreating section to make up the light hydrocarbon stream used in the production of renewable hydrogen.

The invention relates to producing upgraded renewable oil. Renewable crude oil is provided whose oxygen content, water content, and total acid number are within predetermined ranges. Respective fractions of the oil have boiling points below 350° C. and above 450° C. After the oil is pressurized, and hydrogen is added, the mixture is heated and contacted with a heterogeneous catalyst in a first reaction zone with weight based hourly space velocity (WHSV) of 0.1 to 1 h-1. The resultant partially hydrogenated and deoxygenated oil is further heated and contacted with a heterogeneous catalyst in a second reaction zone at WHSV of 0.1 to 1.5 h-1. Low and high boiling point liquid hydrocarbon fractions of the product of the second reaction zone are sent to third and fourth reaction zones, respectively, to be contacted with hydrogen and a heterogeneous catalyst under respective heating conditions and WHSV of 0.1 to 1 h-1.

The invention relates to a cyclic method of producing a hydrogen rich and/or a carbon monoxide rich stream using different materials, a first solid material, a second solid material and a CO.sub.2 sorbent material.

In a first step a first gas stream comprising steam and at least one reductant is brought in contact with the three materials resulting in a hydrogen rich outlet stream.

In a second step, the captured CO.sub.2 from the first step is released and converted to CO to produce a CO rich outlet stream.

The invention further relates to an installation for producing a hydrogen rich and/or carbon monoxide rich stream.

The invention relates to a process for the combined production of hydrogen and carbon dioxide from a hydrocarbon mixture, in which the residual gas of a PSA H.sub.2 (12) is separated by permeation in order to reduce the hydrocarbon content thereof and the hydrocarbon-purified gas is separated at a low temperature to produce a carbon dioxide-rich liquid (22).

The present development is a process to produce commodity chemicals such as methanol and syngas using an integrated plasma catalysis technology. The method comprises providing a fixed or fluidized bed reactor having a microwave plasma flame and a catalyst bed with a catalyst, wherein the catalyst is an alloyed bimetallic nanowire. In the process, the plasma flame fluidizes the catalyst thereby producing a more effective catalyst than the non-fluidized catalyst. It is anticipated that the reactor can have a throughput capacity of up to 30 Lpm/kW and can be effective for the conversion of CO.sub.2, CH.sub.4, air, water, and combinations thereof, through reactions such as pure CO.sub.2 splitting, reverse water gas shift (RWGS) for CO production, methanol synthesis, and plasma reforming of methane, thereby making a system that would be attractive for small GTL units.

A process to efficiently convert organic feedstock material into liquid non-oxygenated hydrocarbons in the C.sub.5 to C.sub.12 carbon skeleton range is disclosed. The process can utilize gaseous, liquid or solid organic feedstocks containing carbon, hydrogen and, optionally, oxygen. The feedstock may require preparation of the organic feedstock for the process and is converted first into a synthesis gas containing carbon monoxide and hydrogen. The synthesis gas is then cleaned and conditioned and extraneous components removed, leaving substantially only the carbon monoxide and hydrogen. It is then converted via a series of chemical reactions into the desired liquid hydrocarbons. The hydrocarbons are suitable for combustion in a vehicle engine and may be regarded a replacement for petrol made from fossil fuels in the C.sub.5 to C.sub.2 carbon backbone range. The process also recycles gaseous by-products back through the various reactors of the process to maximize the liquid hydrocarbon in the C.sub.5 to C.sub.12 carbon skeleton range yield.
