Molten salt pyrolysis of biomass: The mechanism of volatile reforming and pyrolysis

Molten salt pyrolysis of biomass: The evaluation of molten salt

“…It can be found that the pyrolysis process of biomass changes abnormally after the addition of sulfates. The char and methane were rapidly consumed from 250 • C and completely disappeared at about 350 • C. Almost all char derived from biomass pyrolysis was converted into CO 2 (g), and the reactions involved were mainly (15) and (16). As the temperature increased, sulfates went through a more complex conversion process with possible reactions (17) to (20).…”

“…Adinberg et al [4] observed the enhancement of the selectivity regarding the gas product with the molten Na 2 CO 3 -K 2 CO 3 during the fast pyrolysis of cellulose particles. Zeng et al [16] found a significant yield increase of syngas at 750-850 • C with the eutectic Li 2 CO 3 -Na 2 CO 3 -K 2 CO 3 compared with the fast pyrolysis of biomass. Moreover, Wei et al [5] obtained phenols content reaching up to 67% in the pyrolysis of digestate.…”

Catalyst-free synthesis of poly(furfuryl alcohol) using deep eutectic solvents

“…There remains a continuous thrust to utilize renewable resources for the production of high-value products to ensure sustainable development. 1,2 Biomass is one of the important renewable resources and has been used to produce a variety of chemicals via different techniques such as hydrothermal, 3 biochemical, 4 gasification, 5 pyrolysis 6 and thermal catalytic methods. 1 The application of biomass-based chemicals is desirable to reduce our dependency on fossil fuel-based raw materials.…”

“…With the increasing concern about environmental pollution and the energy crisis caused by the overuse of fossil fuels, the development of clean and renewable alternatives is extremely urgent . Bio-oil, the main product from biomass fast pyrolysis, is now regarded as a promising substitute to fossil fuels.…”

“…With the increasing concern about environmental pollution and the energy crisis caused by the overuse of fossil fuels, the development of clean and renewable alternatives is extremely urgent. 1 Bio-oil, the main product from biomass fast pyrolysis, is now regarded as a promising substitute to fossil fuels. However, crude bio-oil contains numbers of O-containing organics, and the high oxygen content of bio-oil leads to a poor economy and market applicability.…”
