Investigation of hydrothermal liquefied bio crude oil from paint waste as a fuel in i c engines

Abstract

Many small- and large-scale manufacturing, automobile and newlineaviation industries generate wastes from paints which are not biodegradable newlineand are extremely problematic if disposed and stored in landfills. The present newlinework aims at using these paint wastes from various manufacturing and newlineautomotive industries to generate a clean transport fuel in the most newlineeconomical and eco-friendly way. newlineIn this study, the plant Prosopis juliflora biomass and paint waste newlinewere collected and characterized to analyse its fuel application properties. newlineHydrothermal liquefaction (HTL) was carried out using plant biomass and newlinepaint waste individually and in mixed form at various proportions for HTL newlinebio-oil production using catalyst. The characterization of the HTL bio-oil was newlineperformed to obtain its physical and chemical properties. The HTL byproducts newlinelike bio-char and HTL wastewater were analysed and its reusability newlinewas studied in detail. newlineThe HTL bio-oil obtained from plant biomass and paint waste newlinethrough hydrothermal co-liquefaction was tested on a 5.2 kW diesel engine to newlinestudy its performance characteristics. Diesel was directly injected into the newlineengine at a nozzle opening pressure of 200 bar at 23and#61616;CA before top dead newlinecentre. The secondary fuel was introduced as port fuel injection before the newlineinlet manifold at a spray angle of 60° and an injection pressure between 2 and newline5 bar using an electronic fuel pump. Dual fuel combustion method was newlineemployed where the secondary fuel (Bio-oil and Gasoline) was introduced in newlinedifferent premixed ratios (Rp s) of 10%, 20% and 30% of the total energy newlineneeded for the experiment calculated using diesel fuel. newline
