Biocrude (fast pyrolysis oil from wood) was hydrotreated to minimize the negative aspects of this fuel. The instability of the oil was reduced by reaction of the most unstable functional groups. Concurrently, the oxygenated component of the oil was also reduced, resulting in an improved energy density. Changes in the physical handling properties were also modified. All of this change was accomp...
A simple and efficient synthesis of aryl and heteroaryl substituted pyrimidines has been developed via initial Knoevenagal, subsequent addition and final cyclization of aldehyde, ethylcyanoacetate and guanidine nitrate. Piperidine has been used as a catalyst. Short reaction time, environment friendly procedure and excellent yields are the advantages of this procedure. All synthesized compounds ...
Catalyst selectivity is associated with well-defined homogeneous active sites. Transition metal complexes and organocatalysts are highly active and selective in the homogeneous phase, and their heterogenization by incorporating them into inorganic solid materials allows combining their excellent catalytic activity with improved separation, recovering and recycling properties. In this article, w...
The aim of this paper is to analyze how different catalyst activity profiles influence the operating strategies of industrial reactors. Based on this analysis a method that can be used to transform information given by laboratory reactor experiments into a form which can be used to estimate the productivity of the catalyst and the quality properties of polymers under industrial conditions is pr...
