Abstract

Dehydration ability of activated marble waste consisting of CaO (62.12%), MgO (26.8%), SiO2 (9.24%) including minor amount of Fe (1.94%), Na (0.70%), P (0.019%), K (0.11%) and Mn (0.13%) was examined in the formation of tetrahydrofuran from biomass derived 1,4-butanediol. An excellent catalytic activity was observed as BDO conversion was 95% with 95% yield of tetrahydrofuran at 375°C. The best reaction conditions were found by studying various reaction parameters such as effect of temperature, flow rate and time on stream study. Activated marble waste was characterized by using XRD, XRF, N2 physisorption, TG/DTA analysis, CO2-TPD, SEM and TEM. The high catalytic activity of AWM was attributed to the presence of high basic nature of the marble waste.

Highlights

? Activated marble waste (AMW) is a novel catalyst for dehydration of BDO to THF.

? High conversion of BDO (95%) and high selectivity of THF (99%) was achieved in vapour phase.

? Basicity of calcium rich marble waste influenced the activity.

? Coke formation during the reaction decreases activity of the catalyst.

? AMW is a cheap and an environmentally friendly catalyst.
