Embodiment Construction
[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only for illustration, and are not intended to limit the present application.
[0024] The whole process of preparing 2-methyltetrahydrofuran by hydrogenating 2-methylfuran in a fixed-bed reactor using the catalyst of the present invention will be described below.
[0025] First, the preparation process of the catalyst used in the present invention is to mix nickel powder with a mass ratio of 42%, aluminum powder with a mass ratio of 54%, and cobalt powder with a mass ratio of 6% to obtain mixture A. Then take 80-100 parts by weight of mixture A and 150-320 parts by weight of organic solvent, put them into a ball mill, and ball-mill until the particle size of the slurry is 30-50 μm, then heat and dry at 120-150°C until the...

Abstract
The invention discloses a new nickel-based catalytic material used in the production of 2-methyltetrahydrofuran, and a method for producing 2-methyltetrahydrofuran by using the material. Nickel powder, aluminum powder and cobalt powder are selected and an organic solvent is added to carry out the process. Ball milling, followed by drying, adding alumina monohydrate and polyethylene as a binder, performing high-speed shear stirring for mixing, extruding into strips, and performing alkali activation after sintering. After preheating, it is gasified, so that it enters the tube reactor in the gaseous state at the calculated flow rate for reaction. The invention improves the strength, realizes the balance between catalyst strength and catalytic activity, improves the overall performance of the catalyst, and The flow rate of 2-methylfuran that is compatible with the reaction temperature, pressure and catalyst characteristics has been obtained through research, which greatly improves the production efficiency and is suitable for large-scale industrial applications.
Description
technical field [0001] The invention relates to the technical field of catalytic materials and additives, in particular to a nickel-based catalytic material used in the production of 2-methyltetrahydrofuran and a method for producing 2-methyltetrahydrofuran using the material. Background technique [0002] 2-Methyltetrahydrofuran is an organic compound with a molecular formula of In industrial production, it is currently an important raw material. It is often used as an organic intermediate and an excellent solvent. It has been widely used in organometallic reactions, automotive fuel additives, and pharmaceutical chloroquine phosphate intermediates. [0003] There are many preparation methods of 2-methyltetrahydrofuran, mainly including glycol method, lactone method and furfural method. Since the fifties in last century, Proskuryakov V A, Shikin N I, Baikova Zh G etc. have just begun to study successively under the effect of catalyst, furfuryl alcohol is reduced to obtain ...
