A process and system for producing a synthetic hydrocarbon having a desired H/C ratio is disclosed. Organic material is biochemically digested in a two stage biodigester for separately producing a hydrogen containing biogas substantially free of methane in a first stage and a methane containing biogas in a second stage. The methane containing biogas is reformed in a first reformer to generate hydrogen gas and carbon monoxide gas, which are then combined in a mixer with the hydrogen containing biogas into a syngas in amounts to achieve in the syngas an overall H/C ratio substantially equal to the desired H/C ratio. The syngas is reacted with a catalyst in a second reformer, a Fischer- Tropsch (FT) reactor, to produce the hydrocarbon. Using a two stage biodigester allows for the generation of separate hydrogen and methane streams, a more economical generation of the FT syngas and reduced fouling of the FT catalyst.

Integrated system for hydrogen and methane production from industrial organic wastes and biomass
The present invention provides a system that has been devised to overcome the two most important limitations for sustained biological hydrogen production, namely contamination of the microbial hydrogen-producing cultures with methane-producing cultures necessitating frequent re-start-up and/or other methanogenic bacteria inactivation techniques, and the low bacterial yield of hydrogen-producers culminating in microbial washout from the system and failure. The system includes a continuously stirred bioreactor (CSTR) for biological hydrogen production, followed by a gravity settler positioned downstream of the CSTR, which combination forms a biohydrogenator. The biomass concentration in the hydrogen reactor is kept at the desired range through biomass recirculation from the bottom of the gravity settler and/or biomass wastage from the gravity settler's underflow. The gravity setter effluent is loaded with volatile fatty acids, as a result of microbiological breakdown of the influent waste constituents by hydrogen-producing bacteria, and is an excellent substrate for methane-forming bacteria in the downstream biomethanator.

A process for separation of solid and liquid components in a distillation whole stillage utilizing airless spray drying is disclosed, which is more efficient and economical than conventional processes. In the process, distillation whole stillage resulting from distillation of fermented biomass is first subjected to an evaporation step for separating the whole stillage into a condensate and a concentrate including water, dissolved solids and suspended solids. The concentrate is then subjected to airless steam spray drying for converting the concentrate into dried solids, steam and vapors. All steam and vapors resulting from the airless steam spray drying step are then redirected as energy source to a processing step upstream of the airless spray drying step. At least some of the steam generated in the airless spray drying step is airless steam.
Disclosed is a method of pretreating biomass in two pretreatment stages as part of a biofuel production process. The first stage pretreatment is carried out by heating the biomass to a first stage temperature of 140°C to 180°C for a first stage time of 30 minutes to 2 hours at a first stage pressure of 105 to 150 psig; and the second stage is carried out by heating the biomass to a second stage temperature of 190°C to 210°C for a second stage time of 2 to 10 minutes at a second stage pressure of 167 to 262 psig. The biomass may be initially conditioned prior to the first pretreatment stage by atmospheric steam heating and adjusting the moisture content of the biomass. Hemicellulose and inhibitors (inhibitory compounds) to downstream hydrolysis and fermentation are preferably removed between the first and second pretreating stages, more preferably after each pretreatment stage.
