“…The authors predicted that, as the pioneer plant showed 30% uncertainty on capital investment and production cost, definitive selection of technology was difficult. Philips et al 93 studied the TEA of obtaining methanol from woody biomass via thermochemical gasification, methanol synthesis, and methanol-to-gasoline (MTG) technologies. Evaluation included comparison of the economics of the three process scenarios: (1) biomass to gasoline, (2) only crude gasoline separation, and (3) the separate product scenario (including light and heavy gasoline, liquified petroleum gas (LPG), and alkylates).…”

Lowering greenhouse gas (GHG) emissions: techno‐economic analysis of biomass conversion to biofuels and value‐added chemicals

It is important for researchers to look at alternative fuels to reduce dependence on fossil fuels as a primary source of energy, to protect the environment, and to reduce greenhouse‐gas emissions. An alternative fuel has to be environment friendly and economically viable, both in terms of production and suitability for the modern world. Fuel derived from biomass has long been viewed as a potential replacement. First‐generation biomass‐derived fuels such as bioethanol and biodiesel have already been competing with conventional fuels, assisted by legislation. This review paper assesses the feasibility of adapting and incorporating second‐generation advanced biofuel production technology for the thermochemical conversion of biomass to produce alternative fuels. The conversion technologies considered here are pyrolysis and gasification, and their potential has been examined using techno‐economic assessment (TEA). A brief overview of different business models that can be incorporated during TEA has also been discussed. Techno‐economic assessment data help in determining costs of technologies if they are employed on a commercial scale, especially in terms of per unit cost of product. The review has compiled the technical and economic data available for assessing the types and combination of processes that can assist competitiveness in the existing market. © 2019 Society of Chemical Industry and John Wiley & Sons, Ltd.

“…The clean syngas was then compressed to 2.0 MPa before it was decarbonized in the Rectisol-based unit. Approximately 90% of the CO2 in the feed gas was removed to achieve the molar ratio of (H2-CO2)/(CO2+CO) = 2.03 and H2/(2CO+3CO2) = 1 in the purified syngas [35,36]. Then, the pure syngas was compressed to the desired operating pressure (8.0…”

The indirect steam gasification of biomass to olefins (IDBTO) coupled with CO2 utilization was proposed and simulated. Energy and exergy efficiencies, net CO2 emissions, and economic evaluation were performed against IDBTO as well as the direct oxygen-steam gasification of biomass to olifins (DBTO).The influences of unreacted gas recycling fraction (RU) and CO2 to dry biomass mass ratio (CO2/B) on the thermodynamic performance of the processes were also studied. The results showed that the yields of olefins of DBTO and IDBTO were 17 wt% and 19 wt%, respectively, the overall energy and exergy efficiencies of the IDBTO were around 49% and 44%, which were 8% and 7% higher than those of the DBTO process, respectively. A higher RU was found favor higher energy and exergy efficiencies for both routes. Besides, for the IDBTO process, it is found that the addition of CO2 to gasification system led to an improvement in both energy efficiency and exergy efficiency by around 1.6%. Moreover, lifecycle net CO2 emission was predicted to be -4.4 kg CO2 eq./ kg olefins for IDBTO, while for DBTO, it was -8.7 kg CO2 eq./ kg. However, the quantitative economic performance of IDBTO was superior to that of the DBTO process.

“…Electricity can be produced using biomass by direct combustion in a thermal power plant, or by gasification to produce a secondary fuel (or energy carrier) which may then be fed to a power plant for the generation of electricity [1] or used as feedstock for fuel production [2,3]. Hence, biomass is an attractive option in the energy mix, as CO 2 emissions during the conversion of biomass to electricity are roughly matched by that sequestered during biomass growth.…”

This study investigates the performance of ultra-microporous cobalt oxide silica membranes for processing simulated gas streams containing toluene as a model tar compound in gasification. The performance of the membranes was initially investigated for He (simulating H 2 ), CO 2 , N 2 and Ar in a range of temperatures. Subsequently, toluene was added to a gas mixture containing He and tested to 2 simulate the effect of toluene as a tar compound in gasification. The membranes delivered molecular sieving features, showing activated transport as the permeation of the smaller molecular gas He increased with temperature whilst the permeation decreased for the other larger molecular gases. Prior to toluene exposure, He permeance increased by almost twofold from 3.6 × 10 -8 to 7.1 × 10 -8 mol m -2 s -1 Pa -1 as the temperature was raised from 50 to 200 °C. Under a feed gas containing 0.24 mol% toluene, He permeance decreased by an average value of 17%. Upon regeneration of the membrane by heat, He permeance was not fully recovered, a clear indication of tar fouling. A toluene balance calculation showed toluene being retained by the membrane.
