1Rapid conversion of cellulose to 5-hydroxymethylfurfural using single and combined metal chloride catalysts in ionic liquid显示文摘Direct conversion of cellulose into 5-hydroxymethylfurfural(HMF) was performed by using single or combined metal chloride catalysts in 1-ethyl-3-methylimidazolium chloride(Cl) ionic liquid.Our study demonstrated formation of 2-furyl hydroxymethyl ketone(FHMK),and furfural(FF) simultaneously with the formation of HMF.Various reaction parameters were addressed to optimize yields of furan derivatives produced from cellulose by varying reaction temperature,time,and the type of metal chloride catalyst.Catalytic reaction by using FeCl3 resulted in 59.9% total yield of furan derivatives(HMF,FHMK,and FF) from cellulose.CrCl3 was the most effective catalyst for selective conversion of cellulose into HMF(35.6%) with less concentrations of FHMK,and FF.Improving the yields of furans produced from cellulose could be achieved via reactions catalyzed by different combinations of two metal chlorides.Further optimization was carried out to produce total furans yield 75.9% by using FeCl3/CuCl2 combination.CrCl3/CuCl2 was the most selective combination to convert cellulose into HMF(39.9%) with total yield(63.8%) of furans produced from the reaction.The temperature and time of the catalytic reaction played an important role in cellulose conversion,and the yields of products.Increasing the reaction temperature could enhance the cellulose conversion and HMF yield for short reaction time intervals(5~20 min).Hussein Abou-Yousef El Barbary Hassan Philip Steele 2013燃料化学学报2013,41,2:4
2Cooling performance of earth-to-air heat exchangers applied to a poultry barn in semi-desert areas of south Iraq显示文摘Earth-to-air heat exchangers(EAHE)can reduce the energy consumption required for heating and cooling of buildings.The composition and the thermal characteristics of the soil influence the heat exchange capacity,and the soil moisture can furthermore affect thermal performance of EAHE.The aim of this study was to compare the thermal performance of EAHE in dry and artificially wetted soil.Tests were carried out in the Basra Province(Iraq),in a semi-desert area.Two experimental EAHE were built in a poultry barn and tested from June 2013 to September 2013.The pipe exchangers were buried at 2 m deep.One heat exchanger operated in dry soil(DE),while the other one operated in artificially wetted soil(WE).In the WE system,a drip tubing placed 10 cm above the air pipe wetted the soil around the exchanger.Air temperatures at the inlet and at the outlet of both the exchangers as well as soil temperature at 2 m deep were continuously monitored.The experimental results confirmed that wetting the soil around EAHE improves the general heat exchange efficiency.The coefficient of cooling performance(COP)of the earth-to-air heat exchangers system was evaluated on the basis of the ratio between the heat removed from the air or added to the air and the energy input.During the day,with an average COP of 6.41,the WE system cooled the air more than the DE system,which reported a value of 5.07.On average,in the hottest hours of the day,the outlet temperature of the WE was 37.35℃ while in the DE it was 38.91℃.Moreover,during the nighttime,the WE system warmed the air more than the DE system.Wasseem Morshed Lorenzo Leso Leonardo Conti Giuseppe Rossi Stefano Simonini Matteo Barbari 2018International Journal of Agricultural and Biological Engineering2018,11,3:2
