Liquid coal characteristic analysis with fourier transform infra red (FTIR) and differential scanning calorimeter (DSC)

The aim of this study is to identify the value of compounds contained in liquid coal by using fourier transform infra-red (ftir) and differential scanning calorimeter (dsc). ftir was used to analyse the components contained in liquid coal,while the dsc is done to observe the heat reaction to the environment. based on the fourier transform infra-red (ftir) test results it is shown that the compound contained in the liquid coal consisting of alkanes,alkenes and alkyne. these compounds are similar compounds. the alkanes,alkenes and alkynes compounds undergo complete combustion reaction with oxygen and would produce co2 and water vapour [h2o(g)]. if incomplete combustion occurs,the reaction proceeds in the form of carbon monoxide co gas or solid carbon and h2o. combustion reaction that occurs in all these three compounds also produces a number of considerable energy. and if it has higher value of carbon then the boiling point would be higher. from the differential scanning calorimetric (dsc) test results obtained some of the factors that affect the reaction speed,which are the temperature,the reaction mixture composition,and pressure. temperature has a profound influence in coal liquefaction,because if liquid coal heated with high pressure,the carbon chain would break down into smaller chains consisting of aromatic chain,hydro-aromatic,or aliphatic. this then triggers a reaction between oil formation and polymerization reactions to form solids (char). © school of engineering,taylor’s university.
