Characterization of Cobalt Catalysts on Biomass-Derived Carbon Supports

2017

Cobalt catalysts are known to have a high activity and selectivity in the Fischer–Tropsch reaction converting synthesis gas to higher hydrocarbons (C5+). These catalysts have been supported by different porous materials. Porous carbon materials like activated carbon (AC) have physical and chemical surface properties that affect the preparation of supported metal catalysts and can easily be tailored. In this study, AC was produced by carbonization and steam activation of lignin, a waste fraction from the Kraft pulping process. A series of Co/AC-catalysts was produced and characterized by several techniques. According to the results, tailored properties (high surface area, mesoporosity) were …

The role of part-time special education supporting students with reading and spelling difficulties from grade 1 to grade 2 in Finland

2018

Previous studies show that many students with reading and spelling problems have a lack of progress in reading and spelling skills after years of special education services. The aim of the study is to evaluate the reading and spelling skills of Finnish children in grades 1 and 2 receiving part-time special education from special education teachers for reading and spelling difficulties (RSD) and for RSD with other learning difficulties. In this study, the focus is in the roles of the form and the amount of part-time special education in reading and spelling skills development. Of 152 children involved in the study, 98 received part-time special education for RSD, and 54 did not have RSD and …
