Calculation methods of direct coal liquefaction using autoclave
Yan Bingfeng
Abstract：Autoclave is commonly used test device for evaluating the performance of direct coal liquefaction.Due to autoclave products are hard to be completely sampled and measured,the inlet and outlet materials and ash are actually out of balance.The accuracy of experimental data on this basis is low,thus it is needed to make a reasonable adjustment of the materials and the ash to achieve the balance.The method to adjust the materials and ash to achieve balance was described,and on the basis of materials balance,oil yield formula of autoclave was modified.The results show that in order to ensure the real test data,the material balance of outlet and inlet is preferably more than 95％,and the ash balance is preferably 90％-110％.The commonly used formula for calculating oil yield is revised.The oil yield calculated by the modified oil yield formula is 1.14％ to 3.42％ higher than that without modification.
