Two different methods of production bio-hydrogenated diesel (BHD), simply called green from rice bran oil (RBO), were performed. In the first route, a direct hydrotreating reaction RBO to BHD catalysed by Pd/Al2O3 was performed in high-pressure batch reactor. Operating conditions investigated as follows: catalyst loading (0.5 1.5% wt.), temperature (325 400 °C), initial hydrogen (H2) pressure (...

Progress in catalysis is driven by society's needs. The development of new electrocatalysts to make renewable and clean fuels from abundant and easily accessible resources is among the most challenging and demanding tasks for today's scientists and engineers. The electrochemical splitting of water into hydrogen and oxygen has been known for over 200 years, but in the last decade and motivated b...

This paper presents two case studies on the performance evaluation and model validation of two industrial multivariate model predictive control (MPC) based controllers at Suncor Energy Inc., Fort McMurray, Canada: (1) a 7 controlled variable (CV), 3 manipulated variables (MV) kerosene hydrotreating unit (KHU) with three measured disturbance variables that are used for feedforward control; and (...

This paper presents the multi-objective optimization of a crude oil hydrotreating (HDT) process with atmospheric distillation unit using data-driven models based on bootstrap aggregated neural networks. Hydrotreating whole has economic benefit compared to conventional individual products. In order overcome difficulty in developing accurate mechanistic and computational burden utilizing such opt...

Aqueous phase recirculation increased the bio-crude yield and energy recovery along with promoting production of N-heterocyclic compounds that lead to harsher required hydrotreating conditions.

Abstract Active sites in Mo-based hydrotreating catalysts are produced by sulfidation. To achieve insights that may enable optimization of the catalysts, this process should be studied situ. Herein we present a comparative XAFS study where situ sulfidation Mo/δ-Al 2 O 3 and Ni/δ-Al is compared to δ-Al supported NiMo with different ratios. The also covers comparison Ni Mo using oxide supports as...

Summarization of electronic discussion fora is a unique challenge; techniques that work startlingly well on monolithic documents tend to fare poorly in this informal setting. Additionally, conventional techniques ignore much of the structures that have the potential to serve as valuable features in the summarization task. We present several novel examples of such features, including the catalys...
