Co-production of biodiesel and hydrogen from rapeseed and Jatropha oils with sodium silicate and Ni catalysts

Long, Yun-Duo; Fang, Zhen; Su, Tong-Chao; Yang, Qing - In: Applied Energy 113 (2014) C, pp. 1819-1825

Calcined sodium silicate was used to rapidly catalyze the transesterification of rapeseed and Jatropha oils to biodiesel under microwave irradiation. Biodiesel yields of 95.8% and 92.8% were achieved from rapeseed and Jatropha oils, respectively (microwave power of 400W, methanol/oil molar ratio...

A review of hydrothermal biomass processing

Tekin, Kubilay; Karagöz, Selhan; Bektaş, Sema - In: Renewable and Sustainable Energy Reviews 40 (2014) C, pp. 673-687

Hydrothermal processing is an important thermochemical conversion process that is used to convert biomass into valuable products or biofuel. The process is usually performed in water at 250–374°C under pressures of 4–22MPa. The biomass is degraded into small components in water. Based on...

Analytical solution of the non-uniform heat exchange in a reactor cooling coil with constant fluid flow

Bogaerts, Ph.; Castillo, J.; Hanus, R. - In: Mathematics and Computers in Simulation (MATCOM) 43 (1997) 2, pp. 101-113

An analytical solution of the partial differential equation describing the enthalpy balance of the cooling fluid in a batch exothermic reactor has been developed for a constant flow. Thanks to an analytical integration on position, the simulation of the process can be performed with one...

Feedforward control of a class of hybrid systems using an inverse model

Karer, Gorazd; Mušič, Gašper; Škrjanc, Igor; … - In: Mathematics and Computers in Simulation (MATCOM) 82 (2011) 3, pp. 414-427

In this paper we describe the design of a control algorithm for MISO systems, which can be modelled as hybrid fuzzy models. Hybrid fuzzy models present a convenient approach to modelling nonlinear hybrid systems.

Are you what you consume? Impact of food, soft drinks, and coffee on cognitive and non-cognitive test scores

Sohnesen, Thomas Pave - 2019

Cognitive and non-cognitive tests are key factors in many aspects of economics, especially within labour market analysis. Non-cognitive tests and personality traits are increasingly used, as these are found to be as critical as cognitive abilities for labour market outcomes, while they might be...
