Catalytic pyrolysis of cellulose over solid acidic catalysts: an environment-friendly method for furan production

Description
Summary:The production of high-valuable chemicals, such as furans, from biomass is a hot topic in the past decade. It used to be abstracted from fossil resources. This paper presents a study on the production of furan compounds via catalytic pyrolysis of cellulose on a two-staged fixed-bed reactor. Four solid acidic catalysts including Nb 2 O 5 , γ-Al 2 O 3 , ZSM-5, and TS-1, were used for the catalytic cracking. The selectivity of furans is 9.6% in a blank test and increased to 43.9% and 20.7% over TS-1 and Nb 2 O 5 , respectively. Nevertheless, ZSM-5 and γ-Al 2 O 3 lowered the furan selectivity to 6.8% and 8.8%, respectively. The relationship between the physicochemical properties of different catalysts and their catalytic selectivity towards furan compounds were discussed based on characterization results of N 2 physisorption, XRD, NH 3 -TPD, Py-IR, and TG/DTG. Graphical abstract Furan compounds were studied in catalytic pyrolysis of cellulose, and high selectivity of furans was achieved over TS-1.
