The new nickel catalyst for vapor phase methanol carbonylationI. Preparation of nickel catalyst supported on phenolic-resine derived active carbon

Nickel supported on phenolic resine derived active carbon(PHAC) for methanol carbonylation was prepared and the preparing conditions were discussed The results showed that reducing temperature, quantity of nickel loading and carbonization heating rate had market effects on the activities of the catalyst At the preparing condition that reducing time 1h, reducing temperature 623K, percentage rate of curing agent, additive and bubbling agent to the resine:16%,15% and 8%; curing temperature 423K and carbonization temperature 873K; nickel loading 7%, carbonization heating rate 4K/min, the activity was highest And the conversion of methanol could reach 93 8%, while the carbonyl compounds yield reached 54 1%.
