The present work reports on the characterization of mixed agro-residue pellets and their subsequent use for syngas generation in a laboratory-scale downdraft gasifier utilizing the mixture of oxygen and steam as the gasifying agent (equivalence ratio/steam to biomass ratio: 0.21/2.15). Pure hydrogen is realized in a vacuum pressure swing adsorption...

The current work reports on the performance characterization of a VPSA system developed in-house for ISO-quality green hydrogen generation using commercially available zeolite 13X from two practical multi-specie feed streams generated from near-ambient oxy-steam and air gasification of casuarina wood chips. The breakthrough dynamics in a packed col...

The article presents an experimental investigation on the generation of hydrogen-rich syngas through oxy-steam gasification of corncobs, a key agro-residue available in many countries, to establish biomass gasification coupled with swing adsorption-based multi-component gas separation as a promising route for renewable methanol production. The gasi...

Thermo-chemical conversion of biogenic sources coupled with downstream carbon dioxide separation offers a potential route to generate carbon-neutral/-negative energy carriers to achieve a sustainable future. The current work emphasizes the possibility of using oxy-steam gasification integrated to a low-pressure separation unit to generate syngas wi...

The full design document for 3Nm3/h (50 LPM) Medical Oxygen Generator is now available under Open Source License from the Indian Institute of Science, Bangalore, India. The same design document will shortly be hosted on the institute website and all further updates and response to general queries will be updated on the same web page. The link fo...

A complete design document with supporting CAD drawings for a 3 NM3/h medical Oxygen generation system

The S3 Medical Oxygen Generator is a device put together at Indian Institute of Science for the generation of Medical Oxygen [O2 93 ± 3 vol%; Balance N2 with CO level: < 5 ppm and CO2 level: < 300 ppm]. The product design is available under Open Source Licensing Terms as an initiative in response to the nCoVID19 crisis. As a part of the design, com...

Solar energy technology has grabbed a worldwide interest and attention these days. India also, having a huge solar influx and potential, is not falling back to feed its energy demand through non-conventional energy sources such as concentrating solar power (CSP) and photovoltaic (PV). This work will try to add some comprehensive insight on solar en...

Low temperature industrial thermal applications like process heating involving solar thermal technology renders the usage of inexpensive air filled annuli receivers despite they are below par in thermal performance. This work is cantered around the air filled receiver system and more importantly try to assess both conventional and modified air fill...

Two type of receiver systems currently employed in solar parabolic trough collector technology are evacuated annuli receivers and air filled annuli receivers. While former receiver finds its way into high temperature grid-acquaintance solar parabolic trough collectors, latter are more inclined towards non-grid solar thermal applications like low-te...

World today is facing an acute shortage of energy. Large amount of energy generated from different mechanical processes is dumped into the environment as a waste heat. This waste heat can be utilized for desalination or purification of water. Several researchers have worked in this particular area of desalination of water using waste heat from diff...

Energy demand in India is increasing continuously due to sharp growth in population and industrial development. Major demand of electricity is fulfilled by conventional energy resources like coal, oil, gas etc. About 13% of installed capacity in India is obtained from renewable energy sources. India being an agricultural rich country has a huge sto...

In the modern world large solid waste is generated by the cities; hence environment pollution has become a cause of concern. The solid waste produced by the cities needs efficient handling to reduce health hazard problems caused by the harmful effect of solid waste. In this regard solid waste management plant has become a prime requirement. In the...

Energy is an important entity responsible for economic growth, urbanization, industrialization and improvement of quality of life in the society. Abrupt rise in energy demand due to growing population and industrialization, depleting fossil fuel resources and compilation with international protocols on environment & climatic change has pushed the w...

Coal-oil slurry (COS) can be used as an alternative to fuel oil and also in the future it can be used as an impressive fuel in thermal power plants of India. These fuels are having many advantages over the conventional fuels such as they can easily be transported over long distances from fuel deposits to consumption sites through pipelines using fl...
