“…As seen in these figures, although a slight decrease in the intensity of the main peaks was noticed after the introduction of copper, all the characteristic peaks of the parent HZSM-5 were observed in Cu/ZSM-5 catalysts, which indicated that the introduction of copper did not destroy the structure of the parent HZSM-5. In addition, two characteristic peaks related to CuO (35.7°and 38.55°) were only observed on 9.5%CuO/ZSM-5 (23), which indicated that Cu species were well dispersed on HZSM-5(50) and . This is in accordance with the SEM result (see Fig.…”

“…2b and c) became sharper than on Cu/ZSM-5(23) and shift to a lower temperature (208.7°C). The shoulder peak at high temperature for 9.7%CuO/ZSM-5(50) was smaller than that of CuO/ZSM-5 (23). For the catalyst 9.2%Cu/ZSM-5(280), only one low-temperature reduction peak was identified.…”

“…In addition, further dehydration of 2,3-BDO yields 1,3-butadiene [19], which can be dimerized to produce the aromatic intermediate styrene (Diels-Alder reaction) [20] and hydrogenated to butene. Sato and coworkers investigated dehydration of 2,3-BDO to 1,3-butadiene over Sc 2 O 3 [21], and dehydration of other diols, such as 1,3-butanediol and 1,4-butanediol over rare earth oxides [22,23], ZrO 2 [24] and Cu-based catalysts [25].…”

“…One of the promising targets is the selective conversion of 1,5‐pentanediol into 4‐penten‐1‐ol, as it is one of the raw materials used to produce polymers . The Sato group has worked on the dehydration of diols over various rare earth oxides, and these authors found that the dehydration selectivity to unsaturated alcohol from 1,5‐pentanediol on ceria remains lower in comparison with other diols, although the reason for such low selectivity to unsaturated alcohols was not defined.

Dehydration of 1,5‐Pentanediol over Na‐Doped CeO₂ Catalysts

The effects of CeO2 doped with Na on the dehydration of 1,5‐pentanediol were studied by using a fixed‐bed reactor at two different temperatures (350 and 400 °C) and atmospheric pressure. For characterization, BET surface area, hydrogen temperature‐programmed reduction, CO2 temperature‐programmed desorption, and diffuse reflectance infrared Fourier transform spectroscopy techniques were utilized. The conversion of the diol on CeO2 was found to depend on Na loading. The selectivity to the desired product (i.e., unsaturated alcohol) increased and the selectivity to undesired products (i.e., tetrahydropyran, tetrahydropyran‐2‐one, cyclopentanol and cylopentanone) decreased with increasing Na content on CeO2. The basicity of hydroxyl groups or surface oxygen on CeO2 was altered with the addition of Na, and controlled the dehydration reaction pathway.

“…111,114 Dehydration of 1,3-BDO into UOLs such as 3B1OL, 2B1OL, and 3B2OL have been investigated over ZrO 2 , 81 solid acid metal oxides, 81 CeO 2 -ZrO 2 , 115 and all of the rare earth metal oxide catalysts. 116,117 In the rare earth oxides, CeO 2 is the most active and selective catalyst. CeO 2 with weak basic sites shows the highest 1,3-BDO conversion at 325°C as well as the sum of selectivity of 2B1OL and 3B2OL over 99%.…”

Global supply of 1,3-butadiene (abbreviated as BD) is faced with problems such as unstable price of petrochemicals and variation of chemical feedstock in recent years. Many research works have been conducted to produce BD from some renewable resources instead of petroleum. Among them, biomass-derived C 4 alcohols such as 1,3-butanediol (1,3-BDO), 2,3-butanediol (2,3-BDO), and 1,4-butanediol (1,4-BDO) have been considered as alternative resources to produce BD. Direct dehydration of butanediols (BDOs) into BD, however, needs high reaction temperatures while the dehydration into their corresponding unsaturated alcohols (UOLs) such as 3-buten-2-ol (3B2OL), 2-buten-1-ol (2B1OL), and 3-buten-1-ol (3B1OL) proceeds at rather low temperatures over specific catalysts. The latter step of BDO dehydration, dehydration of UOLs to BD, is readily catalyzed by solid acids even at lower temperatures than those at which BDOs are dehydrated completely. Thus, efficient formation of UOLs from BDOs would be a key process to produce BD with high selectivity. We summarize the BD production from C 4 alcohols as well as the dehydration of BDOs to UOLs, in addition to the BD production via ethanol dimerization.
