“…Due to the low energy density of biomass obtained directly from nature, effective conversion techniques from biomass to high-value fuels and chemicals are needed. Pyrolysis is probably the most attractive conversion process by which biomass is heated to moderate temperatures in an oxygen/air free atmosphere to yield solid, liquid, and gaseous products. , Compared with other thermochemical processes, pyrolysis is regarded as an efficient and economical technology for converting biomass into higher value fuels. Currently, most of biomass pyrolysis studies have been focused on the fast pyrolysis − owing to its higher yield of liquid products compared to the traditional pyrolysis.…”

Sumac marc, residue from sumac fruit after oil and flavonoids extraction, was used as a raw material for pyrolysis due to its higher lignocellulosic content in the present work. Time-step and temperature-gradient collections of bio-oil from pyrolysis of sumac mar were established to overcome the disadvantage of high aqueous phase content and low heating value of bio-oil from traditional pyrolysis. In addition, the pyrolysis residues were further applied to prepare activated carbon by chemical activation. Experimental results showed that the aqueous phase content of bio-oil decreased from 94.02% to 28.65% by time-step collection at pyrolysis temperature 500 °C with a heating rate 40 °C/min in a sweeping gas reactor. In the temperature-gradient collection, the aqueous phase content of bio-oil obtained at 500 °C was 15.93% and that gave a promising method to obtain high quality bio-oil preparations from pyrolysis. Under the optimized activation conditions, the iodine and methylene blue absorptivities of activated carbon prepared by pyrolysis residues were 1060 mg/g and 250 mg/g respectively, which were accorded with the international quality standards of first grade activated carbon. Consequently, the pyrolysis of sumac marc to produce bio-oil and preparation of activated carbon from pyrolysis residues provide a new approach of sumac marc application, which achieves a total biomass utilization of sumac marc.
