Inductive Heating Assisted-Catalytic Dehydrogenation of Tetralin as a Hydrogen Source for Downhole Catalytic Upgrading of Heavy Oil

Application of carbon nanocatalysts in upgrading heavy crude oil assisted with microwave heating.

Heavy crude oil can be upgraded to lighter oil using several techniques. However, current methods usually require high temperatures, long reaction duration, and cause serious environmental pollution. This study shows that by using carbon nanocatalysts, heavy crude oil can be efficiently upgraded to lighter oil at a relatively low temperature of about 150 °C. The temperature of crude oil was inc...

comparison of catalytic activity of heteropoly compounds in the synthesis of bis(indolyl)alkanes.

heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...

Carbon supports for the catalytic dehydrogenation of liquid organic hydrides as hydrogen storage and delivery system

Hydrogen Production from Selected Kerosine Components by Partial Catalytic Dehydrogenation

The providing and storage of hydrogen for efficient fuel cell systems is an on-going challenge. The partial catalytic dehydrogenation (PCD) of liquid fuels can provide stationary or mobile fuel cell systems with hydrogen. Through PCD, liquid fuels can be treated as hydrogen storage as well as an energy provider for combustion processes. It is also an alternative to the common reforming processe...

Catalytic modification in dehydrogenation properties of KSiH3.

A number of known catalysts, which have been proven to be very effective for several hydrogen species, were studied in order to determine their effects on the hydrogen ab/desorption properties of KSiH3. Among all the catalysts used in this work, mesoporous Nb2O5 is found to be quite effective, with a reduction in activation energy from 142 kJ mol(-1) for pristine KSi to 63 kJ mol(-1) for mesopo...
