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:

Synthetic fuels from natural gas and biomass? New …

Whereas a few years ago, only a small amount of methanol was used directly as a fuel in cars, this use is now increasing rapidly. In China petrol is mixed with methanol (15%) without the need for engines to be redesigned. With some redesigning, more methanol (up to 85%) can be used. The advantage for China is that the methanol can be produced from both coal and biomass via synthesis gas. This emphasis of using methanol as a fuel is reflected in the global production figures for methanol. Thus worldwide, use of methanol as a fuel now accounts for 10% (about 7 million tonnes a year) but is expected to increase in the coming years.

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 .

Natural/shale gas production; Coal conversion to liquid fuels/chemicals/electricity; Biomass conversion to liquid fuels/chemicals/electricity; Hybrid feedstocks (any combination of biomass/coal/natural gas/petroleum) conversion to liquid fuels/chemicals/electricity; Catalysis and reaction engineering for energy applications; Separation technologies for energy applications (e.g., CO2 capture, utilization, storage); Design and synthesis of energy conversion systems

Biofuels produced from various lignocellulosic materials, such as wood, agricultural, or forest residues, have the potential to be a valuable substitute for, or complement to, gasoline. Many physicochemical structural and compositional factors hinder the hydrolysis of cellulose present in biomass to sugars and other organic compounds that can later be converted to fuels. The goal of pretreatment is to make the cellulose accessible to hydrolysis for conversion to fuels. Various pretreatment techniques change the physical and chemical structure of the lignocellulosic biomass and improve hydrolysis rates. During the past few years a large number of pretreatment methods have been developed, including alkali treatment, ammonia explosion, and others. Many methods have been shown to result in high sugar yields, above 90% of the theoretical yield for lignocellulosic biomasses such as woods, grasses, corn, and so on. In this review, we discuss the various pretreatment process methods and the recent literature that has reported on the use of these technologies for pretreatment of various lignocellulosic biomasses.

These main routes are shown in Figure 2, which represents processes that can be used in a biorefinery and provides the structure for the discussion in this unit. The important chemicals now being produced from biomass are discussed, including ethane and propane, ethene and propene and the polymers poly(ethene) and poly(propene), aromatic hydrocarbons, liquid fuels (naphtha, kerosine and diesel), methanol and ammonia.

On the other hand, the feedstock in a biorefinery is biomass which is mainly a mixture of polymeric organic compounds which abound with functional groups, mainly containing oxygen (alcohols, aldehydes, ketones, carboxylic acids, for example). This provides a suitable start for making chemicals but the functional groups have to be removed if we wish to maximise the energy output of gaseous and liquid biofuels for engines.

Heat and pressure-based chemical reactions that produce energy. Through gasification (heating biomass by partial oxidation to produce synthesis gas) and pyrolysis (heating biomass in the absence of oxygen to produce liquid oil), biomass feedstocks can be converted to alcohol and hydrocarbon fuels, chemicals, and power.
