“…Catalytic fast pyrolysis (CFP) is a technology for the production of valuable compounds from solid biomass, which combines fast pyrolysis and catalytic cracking reactions in a single step, to upgrade the biomass pyrolysis products (Yang et al, 2017). Valuable compounds with high yield and selectivity could be produced under different kinds of catalysts, such as aromatic hydrocarbons (Zeng et al, 2018), furfural (Chen et al, 2017b), phenols (Yang et al, 2018), etc.. Monocyclic aromatic hydrocarbons, especially benzene, toluene and xylene (BTX), are multipurpose chemicals that can be used as gasoline additives, solvents, or raw materials for synthesis of a variety of chemical products (such as rubber, plastics, fiber and resin etc.). Soon after the discovery that BTX could be acquired through fast pyrolysis of biomass with cheap zeolite catalysts, CFP of biomass attracted a great deal of research interests (Shen et al, 2016;Wang et al, 2018;Zhang et al, 2013).…”

“…The results indicated that torrefaction improved several fuel characteristics, making the sugarcane bagasse suitable for both domestic and industrial applications. Other possibilities of torrefaction have been applied and studied, such as for microalgae [86], Black Lilac (Sambucus nigra L.) [87], Prosopis juliflora [88], corncob [89], almond and walnut shells [90], bamboo sawdust [91], rice husk [92], and cotton stalk [93], among many others [94].…”

Abstract:The growing search for alternative energy sources is not only due to the present shortage of non-renewable energy sources, but also due to their negative environmental impacts. Therefore, a lot of attention is drawn to the use of biomass as a renewable energy source. However, using biomass in its natural state has not proven to be an efficient technique, giving rise to a wide range of processing treatments that enhance the properties of biomass as an energy source. Torrefaction is a thermal process that enhances the properties of biomass through its thermal decomposition at temperatures between 200 and 300 • C. The torrefaction process is defined by several parameters, which also have impacts on the final quality of the torrefied biomass. The final quality is measured by considering parameters, such as humidity, heating value (HV), and grindability. Studies have focused on maximizing the torrefied biomass' quality using the best possible combination for the different parameters. The main objective of this article is to present new information regarding the conventional torrefaction process, as well as study the innovative techniques that have been in development for the improvement of the torrefied biomass qualities. With this study, conclusions were made regarding the importance of torrefaction in the energy field, after considering the economic status of this renewable resource. The importance of the torrefaction parameters on the final properties of torrefied biomass was also highly considered, as well as the importance of the reactor scales for the definition of ideal protocols.

“…The main compositions of bio-oil were determined using gas chromatography-mass spectrometry (GC-MS; Agilent 7890 A series GC coupled with an HP5975 MS detector) with He. The detail of GC-MS and test method has already been described in our previous study [32]. All the compounds were identified based on NIST mass spectral data library with response factors for GC quantification determined by internal standard method [4].…”

Solar pyrolysis of cotton stalk was carried out in a molten salt reactor heated by 4 kW solar simulator. The effects of pyrolysis temperature and mass ratio of molten salt to biomass on pyrolysis products properties were investigated. The use of molten salt as pyrolysis media increased gas yield. At 850 C, the gas yield (mainly of CO and H 2) continued to rise from 41.35 wt% to 82.57 wt% when mass ratio of molten salt to cotton stalk increased from 0 to 10. Pyrolysis in molten salt significantly decreased bio-oil acids and phenols, while increased aromatics among pyrolysis temperature range of 450e850 C. There was positive correlation between the increased content of aromatics and mass ratio of molten salt to cotton stalk (from 0.5 to 10). The bio-char carbon content showed a general decreasing trend while oxygen, BET surface area and pore volume increased with using molten salt as pyrolysis media. Bio-char obtained from CS1MS5 pyrolysis at 850 C had the highest BET surface area of 972.57 m 2 /g and the biggest total pore volume of 0.6203 cm 3 /g. High quality pyrolysis products with more uniform chemistry suggest catalytic reactions occur inside the solar reactor due to the intermediates degradation with molten salt.
