Thermochemical production of methanol from biomass in Hawaii

Biodiesel production from vegetable oils via catalytic and non-catalytic supercritical methanol transesterification methods

“…Methanol is currently made from natural gas but can be made using wood waste or garbage via partial oxidation reaction into syngas, followed by catalytic conversion into methanol called as biomethanol. Adding sufficient hydrogen to the syngas to convert all of the biomass carbon into methanol carbon would more than double the methanol produced from the same biomass base [37]. The composition of syngas from biomass for producing methanol is presented in Table 4.…”

Application of cassava harvest residues (Manihot esculenta Crantz) in biochemical and thermochemical conversion process for bioenergy purposes: A literature review

“…One of the disadvantages of using biomass as fuel in thermochemical processes is their high moisture content (Phillips et al, 1990). Although the combustion reactions are exothermic processes, the water evaporation is endothermic (Park et al, 2012).…”

“…Figure 3 shows the negative linear relationship between the moisture content and HHV. As the moisture content increases, both the HHV and Low Heating Value (LHV) decrease (Phillips et al, 1990). HHV and LHV are used to describe the heat production of a unit fuel amount during their complete combustion.…”

“…Thermochemical processes are commonly employed for converting biomass into biofuels with high heating value (Phillips et al, 1990;Ferreira et al, 2017). Biomass thermochemical conversion includes a great number of processes, such as direct combustion, liquefaction, gasification, pyrolysis and oxy-fuel combustion (Bridgewater, 2001;Park et al, 2012).…”

Biorenewable Liquid Fuels

“…Biomass and coal can be considered as a potential fuel for gasification and further syngas production and methanol synthesis (Takezawa et al, 1987). Adding sufficient hydrogen to the synthesis gas to convert all of the biomass into methanol carbon then double the methanol produced from the same biomass base (Phillips et al, 1990). Waste material can be partially converted to methanol, for which the product yield for the conversion process is estimated to be 185 kg of methanol per metric ton of solid waste (Brown et al, 1952;Sorensen, 1983).…”
