Dehydration ability of activated marble waste consisting of Ca0 (62.12%), Mg0 (26.8%), Si02 (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 degrees 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, N-2 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.
