Embodiment 1
[0044] A method for removing mechanical impurities and ash in the full fraction of coal tar, comprising the following steps:
[0045] The first step: filter with a filter press to remove impurities with a diameter of 20-50 μm in the whole fraction of coal tar to obtain the first effluent;
[0046] The second step: mixing the first effluent with the diesel fraction at room temperature at a volume ratio of 1:0.1 to obtain a mixed oil;
[0047] Step 3: Use a filter press to filter out the large particles wrapped with impurities of 1-20 μm in the mixed oil, and the effluent is the whole fraction of coal tar from which mechanical impurities and ash have been removed.
[0048] The diesel fraction in the second stage has an aromatics content of 6% and a paraffinic content of 45%.
Embodiment 2
[0051] A method for removing mechanical impurities and ash in the full fraction of coal tar, comprising the following steps:
[0052] The first step: filter with a filter press to remove impurities with a diameter of 20-50 μm in the whole fraction of coal tar to obtain the first effluent;
[0053] The second step: mixing the first effluent with the diesel fraction at room temperature at a volume ratio of 1:0.2 to obtain a mixed oil;
[0054] Step 3: Use a filter press to filter out the large particles wrapped with impurities of 1-20 μm in the mixed oil, and the effluent is the whole fraction of coal tar from which mechanical impurities and ash have been removed.
Embodiment 3
[0056] A method for removing mechanical impurities and ash in the full fraction of coal tar, comprising the following steps:
[0057] The first step: filter with a filter press to remove impurities with a diameter of 20-50 μm in the whole fraction of coal tar to obtain the first effluent;
[0058] Step 2: Mix the first effluent with the diesel fraction at 80°C at a volume ratio of 1:1 to obtain a blended oil;
[0059] Step 3: Use a filter press to filter out the large particles wrapped with impurities of 1-20 μm in the mixed oil, and the effluent is the whole fraction of coal tar from which mechanical impurities and ash have been removed.
