FIELD: process engineering. ^ SUBSTANCE: invention relates to catalyst for dehydration of cyclohexanol to cyclohexane and to method of its production. Proposed catalyst comprises the following components in wt %: calcium carbonate - 16.4-37.0, graphite - 1.0-3.0, and zinc oxide making the rest. Proposed method comprises preparing reaction mix of previously mentioned composition containing sources of zinc oxide and calcium carbonate, moulding, drying, and calcinating. Note here that said mix comprises the following components in wt %: calcium carbonate - 12.4-29.8, carboxymethylcellulose or methylcellulose - 0.1-1.0, and base zinc carbonate making the rest, while graphite is added into amounts sufficient for production of said catalyst. ^ EFFECT: higher strength, lower costs, simplified production, reduced harmful effects. ^ 3 cl, 2 tbl, 2 ex |
