“…These char/coke yields were low compared to those reported for post-RP oil catalysis. [19][20][21][22][23][24][25][26]37 The char and the coke were intricately mixed so we could not distinguish between them. The thermogravimetric analysis method could not distinguish between the coke and the char, and no further analysis was carried out.…”

“…Biocrude oils are complex mixtures of carbohydrate and lignin thermal decomposition products, which cannot be used for most biobased products and fuel applications except after considerable secondary processing. Secondary processing such as catalytic upgrading, – liquid−liquid extraction, – or gasification – increases the cost of the final product and makes it less economically competitive relative to fossil derived products.…”

“…Catalytic studies of biomass pyrolysis products have focused on upgrading of pyrolysis oils (post pyrolysis catalysis) to higher value products, – but most of these studies reported low yields of hydrocarbons, high coke/char yields, and rapid deactivation of the catalysts. Other catalytic studies of whole biomass feedstocks focused on gasification to synthesis gas, – but fractional pyrolysis has not been reported in published literature.…”

Fractional catalytic pyrolysis is a selective in situ conversion of biopolymers into desired products. Fractional catalytic pyrolysis was used to convert the lignin fraction of hybrid poplar wood into high yields of cresols and phenols while the carbohydrate fraction was selectively converted into gaseous products. Ground air-dried biomass was fractionally pyrolyzed at 450−500 °C in a 2-in fluidized bed reactor. The total liquid, gas, and char/coke yields were 33%, 53%, and 12.5%, respectively. The low viscosity liquid products consisted of almost pure phenolics with minor carbohydrate decomposition products. The major liquid components were phenol, cresols, methyl substituted phenols, and small fractions of indene and substituted naphthalenes. The carbon and oxygen contents and high heating value (HHV) of the oil were 71%, 21%, and 30.5 MJ/kg, respectively. About 90 wt % of the gaseous products was carbon monoxide and carbon dioxide, and the rest was a mixture of hydrocarbons.

“…There are a number of plant species with rich flow of chemicals, which could be supplementary sources for liquid fuels and chemical feedstocks. Many laticiferous and resinous species have been screened for their potential as sources of biocrude (Buchanan et al, 1980;Lipinsky, 1981) resulting in identification of potential species as sources of hydrocarbons (Calvin, 1983;Haag et al, 1980;Adams et al, 1984;Bhatia et al, 1988Bhatia et al, , 1989Bhatia et al, , 1993aBhatia et al, , 1993bBhatia et al, , 1993cPadmaja et al, 2009aPadmaja et al, , 2009b. Plant resins contain a number of terpenoids, such as monoterpenes, sesquiterpenes, diterpenes, and triterpenes.…”

Biofuels are non-polluting, locally available, and reliable fuels obtained from renewable sources. The rising cost of petroleum-based liquid fuels, due to the depletion of oil sources, has brought biofuels back into focus. Laticiferous and resinous plants can be used for the production of biofuels by catalytic cracking of their non-polar extracts (biocrude). In the present work six resinous species belonging to the families Rubiaceae, Simaroubaceae, Leguminoseae, Dipterocarpaceae, Pinaceae, and Compositae were selected and studied for their potential to yield biocrude, which can be processed into biofuels. Results of studies carried out on upgrading the biocrudes by catalytic cracking using a commercial catalyst are presented.
