SC-CO2 is cleaner green technology for extraction of algal lipids/oils for algal biodiesel production. This work offers an optimized method for the direct conversion (One-step) of algal biomass to biodiesel using supercritical CO 2 extraction and supercritical methanol transesterification. SC-CO 2...

In recent years, many new solid-state hydrides with a high hydrogen capacity that meet DOE requirement (> 7.5 wt.% H 2 ) have been synthesized as promising on-board hydrogen storage materials. In these hydrides, however, only a small fraction of hydrogen can be released at a desired on-board...

The conversion of C5-C6 sugars into 2-furfural (FA) and 5-hydroxymethylfurfural (HMF) have been considered as key intermediate step in the production of transportation fuels and chemicals from ligno-cellulosic biomass. Typically, the process involves the dehydration reaction of the sugars catalyze...

Presented is a novel gasification application where biomass is steam-gasified and natural gas is steam-reformed simultaneously in a solar reactor. Solar-driven gasification is a proven technology, and can augment the biofuel industry as a domestic fuel source. Gasification performed in an...

The objective of this work is to use thermal pretreatment to separate the complex bio-oil mixture to produce less complex vapor streams of products from 1. light oxygenates (small aldehydes, acids) , 2. furan derivatives, and 3. phenolics. The selective production of products by thermal treatment...

Coke formation appears as a reason for catalyst deactivation and results in undesirable product selectivity in biomass pyrolysis. However, there is no effective way to separate coke and char in the majority of current approaches, which prevents studying coke formation and therefore the real reason...

Hydrolysis of sodium borohydride (NaBH 4 ) over metal catalyst is being accepted as a potential technology to deliver H 2 for portable fuel cells. However, unresolved issues such as minimizing the amount of water and nature of hydration by-product limit the hydrogen storage capacities of NaBH 4 ...

Anthropogenic carbon dioxide (CO 2 ) emissions, major contributors to the greenhouse effect, are considered as the main cause of global warming. So, decrease of CO 2 emitted by large industrial combustion sources or power plants, is an important scientific goal. One of the approaches is based on CO...

Fischer Tropsch (FT) synthesis is a polymerization process where a CH X species is added to a growing aliphatic chain. There are several models of the catalytic chain propagation rate and the termination of the chain growth (e.g. Anderson – Schulz – Flory model). The exact methodology for the...

Depleting oil reserves have encouraged the development of technologies to harness the natural resources to sustain the energy needs. Renewable lignocellulosic biomasses have been focus of many studies but advances in the purification and recovering of the products from the product medium has been...
