Disclosed is a method of producing hydrocarbons from oxygenated hydrocarbon reactants, such as glycerol, glucose, or sorbitol. The method can take place in the vapor phase or in the condensed liquid phase (preferably in the condensed liquid phase). The method includes the steps of reacting water and a water-soluble oxygenated hydrocarbon having at least two carbon atoms, in the presence of a metal-containing catalyst. The catalyst contains a metal selected from the group consisting of Group VIIIB transitional metals, alloys thereof, and mixtures thereof. These metals are supported on supports that exhibit acidity or the reaction is conducted under liquid-phase conditions at acidic pHs. The disclosed method allows the production of hydrocarbon by the liquid-phase reaction of water with biomass-derived oxygenated compounds.

Contact of a crude feed with one or more catalysts produces a total product that includes a crude product. The crude feed may include Micro-Carbon Residue (MCR), oxygen, sulfur, or mixtures thereof. The crude product is a liquid mixture at 25° C. and 0.101 MPa. The crude product may have a MCR residue and / or oxygen content of at most 90% of the MCR residue content and / or oxygen content of the crude feed. In some instances, the crude product may have a sulfur content of about 30% to about 70% of the sulfur content of the crude feed. One or more other properties of the crude product may be changed by at least 10% relative to the respective properties of the crude feed.

Contact of a crude feed with one or more catalysts produces a total product that include a crude product. The crude feed may a total acid number of at least 0.3. The crude product is a liquid mixture at 25° C. and 0.101 MPa. The crude product may have a total acid number of at most 90% of the total acid number of the crude feed. At least one of the catalysts may include one or more Column 6 metals of the Periodic Table and one or more Column 10 metals of the Periodic Table. One or more other properties of the crude product may be changed by at least 10% relative to the respective properties of the crude feed.

A system involving a two-step gasification of a carbonaceous source to produce bulk hydrogen that avoids the early formation of CO2 and obviates the traditional water gas shift (WGSR) step, carbochlorination of a metallic ore the production of metals found in the ore that utilizes carbon monoxide as an oxygen sink, rather than the traditional coke, and carbon oxides management that eliminates major impediments to emission-neutral power generation and the reduction of major metals. The gasification uses a rotary kiln reactor and gas-gas cyclonic separation process to separate synthesis gas into purified hydrogen and purified carbon monoxide. Purified bulk carbon monoxide issued in metallurgical reduction, and purified bulk hydrogen as fuel for an emission-neutral hydrogen combined cycle (HCC) turbine power generation station. The carbochlorination is integrated with: a) the concurrent separation and purification of all metal-chlorides (metchlors) and capture of CO2 for passage to the carbon oxides management system; b) the direct reduction of metchlors to nanoscale metallurgical powders and / or to dendritically-shaped particles, including metchlor reduction for the ultrahigh-performance semiconductor metals of the III-V group; and, c) the reforming of metal-oxides with improved crystalline structure from metchlors. The carbon oxides management collects, stores and directs to points of usage, carbon oxides that arise in various processes of the integrated system, and captures carbon monoxide for process enhancement and economic uses and captures carbon dioxide as a process intermediate and for economic uses.
