Synthesis Gas Biorefinery | SpringerLink

To fully investigate the three ICE operating regimes, experimental investigations were carried out to focus on: 1.) A CI engine operating on ethanol and hydrogen fuel 2.) A CI engine operating on diesel fuel with varying blends of synthesis gas 3.) A SI engine operating on varying blends of synthesis gas

i) the manufacture of synthesis gas (a mixture of carbon monoxide and hydrogen (steam reforming))

Some recent designs use waste heat from the secondary reformer directly to provide heat for the primary reformer.
At this stage the gas contains hydrogen, nitrogen, carbon monoxide and carbon dioxide and about 0.25% methane. As air contains 1% argon, this also accumulates in the synthesis gas.

Synthesis Gas Plants - Plant Process

Synthesis gas formed from gasification of biomass can be converted into  (Figure 2, route 7).

Figure 2 shows possible synthetic routes and products that could be made from biomass in a biorefinery. The routes and products that follow each of the main initial processes, fermentation, gasification and pyrolysis are described below.

Whichever way the methane is obtained, it will contain some organic sulfur compounds and hydrogen sulfide, both of which must be removed. Otherwise, they will poison the catalyst needed in the manufacture of synthesis gas. In the desulfurisation unit, the organic sulfur compounds are often first converted into hydrogen sulfide, prior to reaction with zinc oxide. The feedstock is mixed with hydrogen and passed over a catalyst of mixed oxides of cobalt and molybdenum on an inert support (a specially treated alumina) at ca 700 K.

Synthesis gas gas can be produced from biopmass. The process is outlined in the unit on .

Even though the conversion yield was quite low, this study proved that synthesis gas (syn-gas) can be converted to electricity with the aid of microbes that do not possess the drawbacks of metal catalysts of conventional methods.">

of synthesis gas to methanol and other oxygenated products

Synthesis gas is converted into a hydrocarbon wax (a mixture of long-chain alkanes) by heating it and passing the vapour over a cobalt catalyst (the Fischer-Tropsch process) (Figure 2, route 5). The (SMDS) is a modern development of this process. The hydrocarbon waxes are subsequently catalytically cracked with excess hydrogen () (Figure 2, route 9) to form smaller alkanes, for example:

Another method of producing bio-based propene is via syngas and propan-1-ol. Synthesis gas (carbon monoxide and hydrogen) is used to convert bioethanol to propan-1-ol (Figure 3, route 4):

Hydrogen, synthesis gases and their derivatives

Another way to produce propene is via methanol (produced from biomass via synthesis gas), which is an example of the MTO (Methanol To Olefins) process. (Olefin is the older name for the homologous series, alkenes). Methanol can be converted into high purity ethene and propene via dimethyl ether (Figure 3, routes 10 and 9). Methanol vapour is passed over alumina at ca 600 K. An equilibrium mixture of methanol, dimethyl ether and steam is produced, containing about 25% methanol:

Synthesis of NITROUS OXIDE (Laughing Gas) - …

The results from this doctoral work sheds light into the fundamental aspects of syngas combustion and also provides a foundation for future gasification plant designers and synthesis gas producers, regarding the fuel composition needs of a syngas powered internal combustion engine.

Synthesis description for preparation of NITROUS OXIDE (Laughing Gas)

Hydrogen within synthesis gas formed by gasification of biomass, can be converted into (Figure 2, route 6), by addition of nitrogen from air, and is used mainly to make .

Synthesis and gas sorption behaviour of ZIF-90 with …

Any solid biomass including for example agricultural, city and industrial waste can be used to make synthesis gas using techniques similar to its production from . More recent developments includes a plant in the Netherlands, which is using liquid propane-1,2,3-triol (glycerol), a by-product from the production of , from animal fats and vegetable oils.
