FM Technologies, Inc. (FMT) has developed new methods for joining SiC-to-SiC and SiC-to-metal for use in ethylene production. Global production of ethylene from olefin plants reached over 150 million metric-tons in 2012 according to GPCA, making ethylene one of the largest, by volume,...Read more
Alternatives to Carbon Capture and Storage (CCS) are needed that can use captured CO2 directly or convert it to valuable products , such as fuels , chemicals , plastics , or building materials. This paper will describe a breakthrough process invented and patented by Rutgers called hydrothermal...Read more
Hydrogen may become an important energy carrier in the future. The current technologies for the large scale production of H2, i.e. steam reforming of natural gas and steam gasification of coal, are very energy intensive owing to the need for various
The need for practical solutions to both carbon capture and carbon sequestration becomes imperative as the climatic impact of anthropogenic CO2 emissions become increasingly clear. With current global CO2 emissions increasing beyond 30 gigatons per year , all potential CO2 reservoirs should be...Read more
Deep saline aquifers are considered as a promising option for long-term storage of carbon dioxide. However , risk of CO2 leakage from the aquifers through faults , natural or induced fractures or abandoned wells cannot be disregarded. Therefore , modeling of various leakage scenarios is crucial...Read more

This study investigates the cyclic use of several sorbents for CO2 capture and comparative study of thermodynamic analysis to predict sorbent regeneration conditions and thermal levels where sorbent kinetics change from CO2 absorption to CO2 desorption. It is expected cycling processes with CO2...Read more
It is generally well accepted that an increase in anthropogenic emissions is a leading cause of the increase in levels of carbon dioxide (CO2) , one of the greenhouse gases , in the atmosphere. Generation of electrical power is responsible for a roughly 40% of these emissions. Design...Read more
Introduction
Chemical looping is one of several emerging technology options capable to reduce the carbon dioxide emissions and helping in a diverse range of applications for production of fuels , chemicals and electricity [1-3]. In a general chemical looping process

In order to model the growth of microalgae in a open-pond reactor , a 1000L system has been built and operated under realistic outdoor conditions. Environmental data (light intensity , temperature , pH) were captured with a datalogger and the growth was measured. A phenomenological mathematical...Read more
Thermal DeOxygenation (TDO) refers to a simple , non-catalytic , process which produces highly deoxygenated crude oils from levulinic and formic acids formed by acid hydrolysis of biomass feedstocks. The TDO reaction is a single-step decomposition reaction which converts the neutralized...Read more
The increase in greenhouse gasses concentration in the atmosphere has contributed to global warming in recent decades. Carbon sequestration is one of the solutions to control the CO2 concentration in atmosphere. A pH-swing mineral carbonation is the
