| 520 | |a In recent years, the demand for durene has been increased as the raw material of polyimide. However, traditional synthesis methods of durene require a large number of steps with lower efficiency. In this study, a novel synthesis method of a bifunctional integrated catalyst had been utilized, in which the methanol synthesis catalyst Cu/ZnO/Al2O3 (CZA) and the aromatization catalyst Co-Nb/HZSM-5 were combined, to synthesize durene from syngas in one step. Syngas was converted to methanol and dimethyl ether (DME) followed by the production of different aromatics with a high concentration of durene through the shape selectivity of zeolite. The optimal reaction conditions of 330 °C, 4 MPa, 200 h−1, 3% Co loading, CZA/HZSM-5 = 3:2 and a unique pseudo-physical coating (PC) integrated method were applied to increase durene selectivity up to 39.71% in aromatics. Different techniques such as XRD, BET, XPS and NH3-TPD were employed to characterize different catalysts, and a variety of experiments were proceeded to compare different routes of methanol and FT synthesis. These results explain that the high selectivity of tetra-methylbenzene (tetra-MB) was due to the alkylation of trimethylbenzene (tri-MB) induced by methanol on HZSM-5 surface. This work demonstrated that the integrated catalyst could be advantageous for direct conversion of syngas to tri-MB and finally to the desired durene and it would open up the new avenues in future perspectives. | ||

| abstract |
In recent years, the demand for durene has been increased as the raw material of polyimide. However, traditional synthesis methods of durene require a large number of steps with lower efficiency. In this study, a novel synthesis method of a bifunctional integrated catalyst had been utilized, in which the methanol synthesis catalyst Cu/ZnO/Al2O3 (CZA) and the aromatization catalyst Co-Nb/HZSM-5 were combined, to synthesize durene from syngas in one step. Syngas was converted to methanol and dimethyl ether (DME) followed by the production of different aromatics with a high concentration of durene through the shape selectivity of zeolite. The optimal reaction conditions of 330 °C, 4 MPa, 200 h−1, 3% Co loading, CZA/HZSM-5 = 3:2 and a unique pseudo-physical coating (PC) integrated method were applied to increase durene selectivity up to 39.71% in aromatics. Different techniques such as XRD, BET, XPS and NH3-TPD were employed to characterize different catalysts, and a variety of experiments were proceeded to compare different routes of methanol and FT synthesis. These results explain that the high selectivity of tetra-methylbenzene (tetra-MB) was due to the alkylation of trimethylbenzene (tri-MB) induced by methanol on HZSM-5 surface. This work demonstrated that the integrated catalyst could be advantageous for direct conversion of syngas to tri-MB and finally to the desired durene and it would open up the new avenues in future perspectives. |

In this study, a novel synthesis method of a bifunctional integrated catalyst had been utilized, in which the methanol synthesis catalyst Cu/ZnO/Al2O3 (CZA) and the aromatization catalyst Co-Nb/HZSM-5 were combined, to synthesize durene from syngas in one step. Syngas was converted to methanol and dimethyl ether (DME) followed by the production of different aromatics with a high concentration of durene through the shape selectivity of zeolite. The optimal reaction conditions of 330 °C, 4 MPa, 200 h−1, 3% Co loading, CZA/HZSM-5 = 3:2 and a unique pseudo-physical coating (PC) integrated method were applied to increase durene selectivity up to 39.71% in aromatics. Different techniques such as XRD, BET, XPS and NH3-TPD were employed to characterize different catalysts, and a variety of experiments were proceeded to compare different routes of methanol and FT synthesis. These results explain that the high selectivity of tetra-methylbenzene (tetra-MB) was due to the alkylation of trimethylbenzene (tri-MB) induced by methanol on HZSM-5 surface. This work demonstrated that the integrated catalyst could be advantageous for direct conversion of syngas to tri-MB and finally to the desired durene and it would open up the new avenues in future perspectives.</subfield></datafield><datafield tag="650" ind1=" " ind2="7"><subfield code="a">Aromatics</subfield><subfield code="2">Elsevier</subfield></datafield><datafield tag="650" ind1=" " ind2="7"><subfield code="a">Durene</subfield><subfield code="2">Elsevier</subfield></datafield><datafield tag="650" ind1=" " ind2="7"><subfield code="a">Methanol synthesis catalyst</subfield><subfield code="2">Elsevier</subfield></datafield><datafield tag="650" ind1=" " ind2="7"><subfield code="a">HZSM-5</subfield><subfield code="2">Elsevier</subfield></datafield><datafield tag="650" ind1=" " ind2="7"><subfield code="a">Niobium</subfield><subfield code="2">Elsevier</subfield></datafield><datafield tag="650" ind1=" " ind2="7"><subfield code="a">Syngas</subfield><subfield code="2">Elsevier</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Jiao, Lengkang</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Nawaz, Muhammad Asif</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Cheng, Like</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Meng, Chen</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Yang, Tianhui</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Tariq, Muhammad</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Liu, Dianhua</subfield><subfield code="4">oth</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="n">Elsevier Science</subfield><subfield code="a">Dong, Ran ELSEVIER</subfield><subfield code="t">Plasticity in responses to dimensional variations of soil space in 19 grassland plant species</subfield><subfield code="d">2022</subfield><subfield code="g">Amsterdam [u.a.]</subfield><subfield code="w">(DE-627)ELV008347182</subfield></datafield><datafield tag="773" ind1="1" ind2="8"><subfield code="g">volume:200</subfield><subfield code="g">year:2019</subfield><subfield code="g">day:8</subfield><subfield code="g">month:06</subfield><subfield code="g">pages:103-112</subfield><subfield code="g">extent:10</subfield></datafield><datafield tag="856" ind1="4" ind2="0"><subfield code="u">https://doi.org/10.1016/j.ces.2019.02.006</subfield><subfield code="3">Volltext</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_USEFLAG_U</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_ELV</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">SYSFLAG_U</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">FID-BIODIV</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">SSG-OLC-PHA</subfield></datafield><datafield tag="951" ind1=" " ind2=" "><subfield code="a">AR</subfield></datafield><datafield tag="952" ind1=" " ind2=" "><subfield code="d">200</subfield><subfield code="j">2019</subfield><subfield code="b">8</subfield><subfield code="c">0608</subfield><subfield code="h">103-112</subfield><subfield code="g">10</subfield></datafield></record></collection>
