Abstract
550,105. Nickel catalysts. WILSON, C. L., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. June 16, 1941, No. 7605. [Class 1 (i)] [Also in in Group IV] Tetrahydrofuran is prepared by contacting tetrahydrofurfuryl alcohol in the vapour phase with nickel or a nickel-containing catalyst at a temperature about 200‹C. The following examples of the preparation of catalysts are given:-(1) nickel-on-pumice prepared by fusing nickel nitrate hexahydrate with granular pumice and passing first air at 400‹C., and then hydrogen at 300‹-350‹C. through the product when packed into the catalyst chamber ; the activity of the catalyst is enhanced by heating it to 550‹-600‹C., re-oxidizing in a stream of air and again subjecting it to the treatment with hydrogen; (2) a nickel-on-silica catalyst prepared by heating silica gel with nickel nitrate, nickel carbonate and water, and reducing the granular product in the catalyst chamber with hydrogen ; (3) a catalyst made by heating granulated pumice with a mixture of nickel nitrate, copper nitrate and manganese nitrate in water, and passing hydrogen through the product; (4) a catalyst prepared by passing first chlorine and then alternately hydrogen and air through a reaction tube containing compact rolls of nickel gauze until hydrogen chloride is no longer evolved, when a final oxidation and reduction treatment is given; the catalyst may be reactivated by passing a slow stream of hydrogen through it, or a stream of air followed by hydrogen may be used ; (5) a catalyst obtained by the alternate oxidation and reduction of pieces of gauze made of a copper-nickel alloy; (6) a catalyst prepared by passing hydrogen chloride through granulated Raney alloy nickel-aluminium at 400‹-450‹C., followed by air at 550‹C., and hydrogen at 350‹C.
