Pyroliq 2019: Pyrolysis and Liquefaction of Biomass and Wastes

Plant diseases are a threat to the health and functionality of both natural and man-made ecosystems. Diverse methods and strategies are being employed to prevent, ameliorate or control plant diseases. Unsustainable practices such as use and misuse of synthetic fungicides have caused severe harm to human health, wildlife and the environment (1). Fungal cause the most destructive plant diseases and impose major losses to both natural and production systems, and one of it is the fungi. Botanical fungicides are particularly sought after because they are abundant, selective, readily degraded, and are not toxic to mammals (2).

Upgrading Of Wheat/Barley And Miscanthus Bio-Oil Over A Sulphided Catalyst, Bogdan Shumeiko, Miloš Auersvald, David Kubička, Petr Straka, Pavel Šimáček, Dan Vrtiška

Pyroliq 2019: Pyrolysis and Liquefaction of Biomass and Wastes

In recent years, the production of biofuels from non-food crops wastes and harvesting residues plays an important role in the improvement of the global environment and in the replacement of declining oil reserves¹. Hydrogenation of lignocellulosic bio-oil is attracting much attention as a suitable way to produce petroleum-refinery compatible feedstock. Primarily, hydrogenation of bio-oil is carried out under severe reaction conditions in two-stage fixed-bed reactors, filled with a noble metal catalyst in the first zone and with a sulphided catalyst in the second zone². This setup allows producing low-oxygen upgraded bio-oil, however, it is economically unviable …

Challenges And Opportunities For The Synthesis Of Novel Pyrolysis Oil Refineries, Manuel Garcia-Perez, Anamaria Pp Pires

Pyroliq 2019: Pyrolysis and Liquefaction of Biomass and Wastes

Bio-oil derived from fast pyrolysis of lingo-cellulosic materials is among the most complex and inexpensive raw oils that can be produced today. Although commercial or demonstration scale fast pyrolysis units can readily produce this oil, this industry has not grown to significant commercial impact due to the lack of bio-oil market pull. In this presentation we will review the challenges and opportunities for bio-oil upgrading and refining. Pyrolysis oil consists of six major fractions. (water 15-30 wt.%, light oxygenates, 8-26 wt. %, mono-phenols, 2-7 wt.%, water insoluble oligomers derived from lignin 15-25wt.%, and water soluble heavy molecules 10-30 wt.%). The …

Ablative Fast Pyrolysis Of Biomass: A New Demonstration Project In California, Usa, Dietrich Meier, Christoph Eusterbrock, Brian Gannon

Pyroliq 2019: Pyrolysis and Liquefaction of Biomass and Wastes

California is the fifth largest economy in the world and has about 40 million inhabitants. The California federal government has decided to stick to the Paris climate change agreement by 2030. For many years, California has been feeling the effects of global warming caused by the largest tree extinction in modern history, a five-year dry spell and resulting bark beetle plague, and severe forest fires coupled with heavy winds, heavy rains, and rising sea levels. California is therefore promoting the use of biogenic fuels in the transport sector. In spring 2017, there was a grant funding opportunity from the California …

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 …

Fundamental Study And Applications To Biomass Pyrolysis Of The Mechanically Fluidized Reactor, Valentina Lago, Franco Berruti, Cedric Briens

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

Lignin has great potential for the production of aromatics currently derived from petroleum, since it is the most abundant source of aromatics in nature. At present, Kraft lignin is used as fuel within the pulping process but, alternatively, it could be converted to high-value chemicals using thermochemical processes such as pyrolysis. Kraft lignin, however, is a very cohesive and thermally sensitive powder with foaming and agglomerating tendency under reaction conditions. Consequently, a novel reactor design, designated as Mechanically Fluidized Reactor (MFR) has been developed to successfully process Kraft lignin.

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 …
