Catalytic upgrading of pyrolysis vapors from lignite over mono/bimetal-loaded mesoporous HZSM-5

By a News Reporter-Staff News Editor at Chemicals & Chemistry -- Investigators publish new report on Fuel Research. According to news reporting from Jiangsu, People’s Republic of China, by VerticalNews journalists, research stated, “HZSM-5 was modified via alkaline treatment and wet impregnation method which loading transition metals (Co, Mo-Co and Ni-Co). The performance of catalysts for the catalytic fast pyrolysis of lignite was tested in a drop tube reactor at 600 degrees C. In comparison to non-catalytic experiment, the chemical composition of upgrading tar was obviously simplified, which mainly contains light aromatics such as benzene, toluene, ethylbenzene, xylene and naphthalene (BTEXN).”

Funders for this research include National Natural Science Foundation of China, Natural Science Foundation of Jiangsu Province.

The news correspondents obtained a quote from the research from the China University of Mining and Technology, “The yield of BTEXN was significantly increased from 12.9 to 26.4 mg/g when Ni/Co-H-5 was used. Meanwhile, the Ni/Co-H-5 treated by NaOH solution achieved considerable deoxygenation performance (86.6%) than other ones. The addition of bimetallic Mo-Co or Ni-Co significantly enhanced the BTEXN selectivity of HZSM-5. Ni promoted H-2 formation in gaseous product and caused the decrease of naphthalenes yield. Whereas the yields of toluene and o-xylene increased after the pyrolysis vapors pass through Mo/Co-H-5. The zeolite treated by NaOH solution (AT-HZSM-5) favors the generation of aromatics and phenolics, conversely naphthalene derivatives. Moreover, AT-Mo/Co-H-5 and AT-Ni/Co-H-5 inhibited the coke formation.”

According to the news reporters, the research concluded: “A catalytic pathway was also proposed to describe the diffusion process of pyrolysis vapors on the active site of catalyst.”
