Process for recovery of nickel from spent catalyst ...

Mar 05, 2015· A brief comparison of catalyst prices shows that a simple metal like nickel is superior to Pd, Pt, Au, Rh (Figure 1). At the moment, these noble metals are … Spent nickel catalyst is generated by various chemical and industrial processes particularly in hydrogenation of natural oils and fats. The spent catalyst generated by the Malaysian palm oil industry usually comes from two processes: hydrogenation of soft oils to fat or hydrogenation of fatty acids of high iodine value (IV) to fatty acids of low IV.

Nickel recovery from spent Raneynickel catalyst through ...

Recovery of nickel from a spent catalyst in an ammonia plant was studied by Ivascanu and Roman, in which 99% of the nickel was recovered as nickel sulfate by nickel leaching in sulfuric acid solution under the following conditions, particle size of 0.09 mm, 80% sulfuric acid solution, reaction time of 50 min and temperature of 70 °C. The nickel based catalysts were investigated in the partial oxidation of natural gas to the feedstock CO/H 2, showing a fairly good performance [12].The promoted catalysts were prepared by a wet impregnation method, with the addition of rare earth oxide like Y 2 O 3, CeO 2, etc.The catalytic performances were compared for the ceria promoted nickel catalysts.

Nickel recovery from spent Raneynickel catalyst through ...

NICKEL (Data in metric tons of nickel content unless otherwise noted) ... a company in Missouri constructed a facility to recover metals, including nickel, from mine tailings. ... superalloys, electroplating, and other uses including catalysts and chemicals. Domestic production of stainless steel recovery is possible which leaves the remaining portion to be treated or disposed by other methods. Treatment of Spent Nickel Catalyst 2 4 4 2 Recovery of metals and other components from the spent catalysts is possible, and the technology for metals reclamation is well established. For catalysts containing Mo, Ni, Co, V and Al 2 O 3

Recovery and Reduction of Spent Nickel Oxide Catalyst via ...

Sep 23, 2014· We are currently involved in spent nickel catalyst recycling. We work with a process to recover the left over nickel residue. We can recover nickel from nickel powder, nickel sludge, nickel fines, nickel shavings, nickel grindings, nickel grinding sludge, nickel dust, low bearing nickel waste, nickel byproduct or high bearing nickel waste. Nickel catalysts used in various operations become spent after several cycles of use, for which a very simple and innovative process is developed at NML for recovery of nickel. The processing step consists of direct acid leaching in presence of a promoter followed by impurity removal to produce nickel …

Nickel recovery from spent nickel catalyst | Request PDF

In this study, recovery of nickel from spent catalyst from palm oil hydrogenation process is carried out via extractive leaching process using sulfuric and hydrochloric acids. RECOVERY OF NICKEL FROM PICKLING SLUDGE ... Apart from HDS catalyst, other waste materials like low grade nickel ore, sludge and ... Joseph and Hogg, 2011) are also exploited to recover nickel ...

G2747A Nickel Catalyst - Agilent

metal recovery from nickel catalyst is also extremely important from an economic point of view, as these metals command a sig-nificant price in the market. Market price of nickel metal equal to 40,000$/ton, so recovery and resale of nickel from spent -alyst is profitable. Finally, in many countries all over the world, By leaching the spent catalyst with hydrochloric acid, Chandhary et al. found the recovery of nickel from a low grade spent catalyst to be 17.7%. Vicol et al. [4] tried to recover nickel by extraction of the spent catalyst with an aqueous solution of 15–23% ammonia at 60–90 o C and at pH 7.5–9.

Disposal of nickel catalyst after hydrogenation of edible ...

Part II: a hydrochloric acid leaching process for the recovery of nickel value from a spent catalyst, Hydrometallurgy, 34(2), 137-150 (1993) Lee J.Y., Rao S.V., Kumar B.N., Kang D.J. and Reddy B.R., Nickel recovery from spent Raneynickel catalyst through dilute sulfuric acid leaching and soda ash precipitation, J. Hazard. electrolysis conditions on Nickel recovery from spent catalyst leachate. Then statistical regression and linear genetic programming are used as simulating tools in predicting Current Efficiency (CE) of Electro deposition cell used for recovery of nickel from spent nickel catalyst. ...

Leaching of nickel from supported nickel waste catalyst ...

Nickel Recovery Nickel/Cobalt rich filtercake material is recovered by steam drying. The resulting concentrate can then be re-used or recycled. We also recover other valuable metals such as copper, tin and cobalt. Processes used include precipitation, steam stripping, sludging and steam drying.

Raney Nickel – Properties and Application

Keywords: Nickel, oil, spent nickel catalyst, hydrochloric acid, recovery. Introduction Nickel is cheap, sufficiently active, and allows suitable catalysts to be economically produced 1. Large quantity of spent nickel catalysts is available from fertilizer, petrochemical, pharmaceuticals vegetables oil and other industries and disposal This indicates that the catalyst derived from nickel(II) triflate is more prone to alteration by coordination of substrates. Therefore, for this substrate class, nickel(II) iodide‐based catalysts should be employed. To demonstrate the broad applicability of the present nickel catalyst, we investigated aryl alkyl alkynes 11 next (Scheme 4).
