Embodiment 1
[0031] In this embodiment, the preparation method of the ceramic fiber-based catalyst carrier specifically includes the following steps:
[0032] Step 1, making paper by mixing 0.1 part of ceramic fiber, 80 parts of glass fiber, 10 part of synthetic fiber and 0.1 part of natural fiber;
[0033] Step 2. After papermaking, extrude it into a paper with a concave-convex surface. The obtained paper with a concave-convex surface is bonded to the flat paper through silica sol to form a layered body, and the layered body is stacked or wound into a honeycomb profile ;
[0034] Step 3: cutting the obtained profile into a desired shape, heating and removing part of the organic matter, including synthetic fibers, natural fibers and some organic binders, to obtain the catalyst carrier.
[0035] The catalyst carrier prepared in this embodiment has a porosity of 93% to 95%, and a heat-resistant temperature ≥ 600°C.
Embodiment 2
[0037] In this embodiment, the preparation method of the ceramic fiber-based catalyst carrier specifically includes the following steps:
[0038] Step 1, mixing 80 parts of ceramic fiber, 0.1 part of glass fiber, 10 parts of synthetic fiber and 10 parts of natural fiber to make paper;
[0039] Step 2. After papermaking, extrude it into a paper with a concave-convex surface. The paper with a concave-convex surface is bonded to the flat paper through aluminum sol to form a layered body, and the layered body is stacked or wound into a honeycomb profile ;
[0040] Step 3, cutting the obtained profile into a desired shape, heating to remove part of the organic matter therein, and obtaining the catalyst carrier.
[0041] The catalyst carrier prepared in this example has a porosity of 90-93%, and a heat-resistant temperature of ≥600°C.
Embodiment 3
[0043] In this embodiment, the preparation method of the ceramic fiber-based catalyst carrier specifically includes the following steps:
[0044] Step 1, mixing 80 parts of ceramic fiber, 80 parts of glass fiber, 0.1 part of synthetic fiber and 10 parts of natural fiber to make paper;
[0045] Step 2. After papermaking, extrude it into a paper with a concave-convex surface. The obtained paper with a concave-convex surface is bonded to the flat paper through silica sol to form a layered body, and the layered body is stacked or wound into a honeycomb profile ;
[0046] Step 3, cutting the obtained profile into a desired shape, heating to remove part of the organic matter therein, and obtaining the catalyst carrier.
[0047] The catalyst carrier prepared in this example has a porosity of 91-94%, and a heat-resistant temperature ≥ 600°C.
