Development of local technologies is crucial to the sustainable energy agenda in resource-limited countries and the world. Strengthening local green technologies and promoting local utilization will reduce carbon emissions that could be generated during transportation and delivery of green products from one country to another. In this paper we developed bio-oil/diesel blends using a low-tech pyrolysis system designed for smallholder farmers in developing countries and tested their appropriateness for diesel engines using standard ASTM methods. Corn stover retrieved from smallholder farmers in Gayaza, Uganda were pyrolyzed in a batch rocket stove reactor at 350 °C and liquid bio-oil harvested. Bio-oil …

Development Of A Mobile 100 Kg/H Plant For Pyrolysis Using A Mechanically Fluidized Reactor, Dhiraj Kankariya, Stefano Tacchino, Dominic Pjontek, Franco Berruti, Cedric Briens

5th International Congress on Green Process Engineering (GPE 2016)

Current pyrolysis processes perform the thermal decomposition of biomass into a liquid bio-oil, bio-char and non-condensable gases, at around 500 °C, without the addition of oxygen gas. The bio-oil is a complex mixture of many components that is used either as a substitute for fuel oil or for applications such as liquid smoke and bio-phenol resins that do not require pure chemicals.

The large-scale mechanical fluidized reactor (MFR) is a new technology for the pyrolysis of biomass developed by ICFAR, which does not require a sand bed and, thus, provides an undiluted solid char residue, which is essential to realize …

Catalytic Property Of Olivine For Bio-Oil Gasification, Mohammad Latifi, Franco Berruti, Cedric Briens

5th International Congress on Green Process Engineering (GPE 2016)

Introduction

Biomass is an attractive renewable source of fuel and energy. Thermochemical processes can convert biomass to a liquid bio-oil or to a syngas. The advantage of using bio-oil as an intermediate is that, in contrast with both raw biomass and gas, it can easily be produced in small distributed units, stored and transported. Not only can platform chemicals and clean fuels be produced from syngas, but hydrogen is itself an alternative fuel. A high hydrogen production is usually desired: for example, methanol production requires a syngas with a molar H₂/CO ratio of 2. Therefore, maximum hydrogen production …

Hydrothermal Treatment Of Bio-Oil For The Production Of Biodiesel Antioxidants, Noemí Gil-Lalaguna, Ana Bautista, Lucía Botella, Alberto Gonzalo, José Luis Sánchez, Jesús Arauzo

5th International Congress on Green Process Engineering (GPE 2016)

1. INTRODUCTION

Fuel consumption is inevitable for industrial development and growth of any country. In the last years, diesel fuels have gained an increasingly important role in the transportation sector. However, the rapid depletion of crude oil resources, as well as the worldwide concern about the environmental damage related to the increase in the emissions of carbon dioxide and other pollutants, has led to an increasing awareness about the development and use of renewable fuels. In this context, biodiesel appears as a good alternative to fossil diesel because of its renewable and biodegradable character, also being a non-toxic and clean fuel …

Bio-Oil And Biodiesel As Biofuels Derived From Microalgal Oil And Their Characterization By Using Instrumental Techniques, Dipesh Kumar, Bhaskar Singh, Kuldeep Bauddh, John Korstad

College of Science and Engineering Faculty Research and Scholarship

Microalgal oil has been a source for production of biofuels such as bio-oil and biodiesel. These two biofuels can be characterized quantitatively using advanced instrumentation techniques. Nile red fluorescence method, PAM fluorometry, NMR, GC/GC-MS, and FTIR are among the major techniques available for characterization and quantification of algal oil. NMR is a rapid and nondestructive analytical technique as it requires minimal sample preparation, and even one intact algal cell can be analyzed. It can also be used for continuous monitoring of cellular composition of algal culture. NMR can be used to monitor transesterification reaction and oxidation of lipids and biodiesel …
