Abstract Cyclohexanol is an important feedstock in the chemical industry and the selective hydrodeoxygenation of lignin-derived guaiacol to cyclohexanol have gained increasing research attention in recent years. In this work, a series of nanoporous metal catalysts were employed for the hydrodeoxygenation of guaiacol and nanoporous Ni (NP-Ni) exhibited high …
The phase evolution, nucleation, and sintered ceramics of barium titanate (BaTiO3, BT) powder prepared by solid-state synthesis with an ultrafine starting material (27 m2/g of BaCO3 and 190 m2/g of TiO2) were investigated in this study. Surface diffusion between BaCO3 and TiO2 was observed at a relatively low temperature of 400 °C by transmission electron …

7.1 Carrageenan production methods. There are two different methods of producing carrageenan, based on different principles. In the original method - the only one used until the late 1970s-early 1980s - the carrageenan is extracted from the seaweed into an aqueous solution, the seaweed residue is removed by filtration and then the carrageenan is recovered from the …
Raymond mills were usually used to make pulverized coal in the United States. The fineness of finished product varies between 250-325 mesh (fineness and output can be adjusted during operation). With the development and improvement over the years, there are more and more types of Raymond mills. Since China introduced this machine, Raymond mill ...
