normally called producer gas consisting primarily of hydrogen (H2) and carbon monoxide (CO), with lesser amounts of carbon dioxide (CO2), water (H2O), methane (CH4), and higher hydrocarbons (CxHy), as well as nitrogen (N2) and particulates The gasification is carried out at elevated temperatures, 500 C and 1500 C and at atmospheric or elevated pressures The process involves conversion of biomass, which is carried out in absence of air or with less air than the stoichiometric requirement of air for complete combustion Partial combustion produces carbon monoxide as well as hydrogen which are both combustible gases Solid biomass fuels, which are usually inconvenient and have low efficiency of utilization, can be converted into gaseous fuel The energy in producer gas
FUELS FROM WOOD
is 70 to 80 percent of the energy originally stored in the biomass The producer gas can serve in different ways: it can be burned directly to produce heat or can be used as a fuel for gas engines and gas turbines to generate electricity; in addition, it can also be used as a feedstock (syngas) in the production of chemicals, for example, methanol The diversified applications of the producer gas make the gasification technology very attractive A variety of biomass gasifiers have been developed and can be grouped into four major classes: (a) fixed bed updraft or countercurrent gasifier, (b) fixed bed downdraft or cocurrent gasifier, (c) bubbling fluidized bed gasifier, and (d) circulating fluidized bed gasifier Differentiation is based on the means of supporting the biomass in the reactor vessel, the direction of flow of both the biomass and oxidant, and the way heat is supplied to the reactor The processes occurring in any gasifier include drying, pyrolysis, reduction, and oxidation The unique feature of the updraft gasifier is the sequential occurrence of the chemical processes: they are separated in relative position in the gasifier and therefore by time As an illustration, using the updraft gasifier (Fig 102), biomass and air are fed in an opposite direction In the highest zone, biomass is heated up and releases its moisture In the pyrolysis zone, biomass undergoes a further increase in temperature and decomposes into hydrocarbons, gas products, and char in the temperature range of 150 to 500 C The major reactions are: Biomass CxHy + CxHyOz + H2O + CO2 + CO + H2

The hydrocarbon fraction consists of methane to high-boiling tar The composition of this fraction can be influenced by many parameters, such as particle size of the biomass, temperature, pressure, heating rate, residence time, and catalysts The operative reactions are: C + CO2 2CO C + H2O H2 + CO 2C + 2H2O 2H2 + CO2 + CO C + 2H2 CH4 CO + H2O CO2 + H2 CO + 3H2 CH4 + H2O The composition of the producer gases varies widely with the properties of the biomass, the gasifying agent, and the process conditions Depending on the nature of the raw solid feedstock and the process conditions, the char formed from pyrolysis contains 20 to 60 percent of the energy input Therefore the gasification of char is an important step for the complete conversion of the solid biomass into gaseous products and for an efficient utilization of the energy in the biomass The producer gases from the reduction zone rise beyond the reduction zone When they come into contact with the cooler biomass, the temperature drops down and the aforementioned reactions are frozen The unreacted char further undergoes the oxidation with air in the lowest zone: C + O2 CO2 As a result, ash is left at the bottom of the reactor The produced carbon dioxide flows upward and is involved in the reactions in the reduction zone The heat released in the oxidation zone drives both the reduction and pyrolysis processes 1042 Liquid Fuels As already noted (Sec 1041), wood can be used to make both liquid and gaseous fuels When wood is heated in the absence of air, or with a reduced air supply it is possible to produce a liquid fuel which can be used in a similar way to conventional oil fuels It can be used to run internal combustion engines in vehicles or generators The gas produced from wood is a mixture of hydrogen and carbon monoxide (synthesis gas) which is similar to the coal gas which was made before the arrival of natural gas from the North Sea This wood gas can be used in internal combustion engines or in gas turbines which can be used to power generators Although the liquid fuels are rarely produced from wood at present, wood gas is important in other countries for producing electricity in more remote areas Processes for making liquid fuels from wood have been understood and available for longer than such fuels have been used in vehicles for transportation However, the economics of liquid fuels from wood as compared to liquid fuels from fossil fuels have been unfavorable Nevertheless, the recent phenomenal increases in the cost of gasoline and diesel fuel, that seem to bear little relationship to the increases in petroleum process, has caused a renewed interest in liquid fuels from sources other than petroleum Wood is a fuel source of interest! The three approaches that are most promising for making liquid fuels from wood are methanol, ethanol, and diesel fuel, but other liquid fuels from wood are possible
