Oligomerization of C2-C4 Hydrocarbons in the Presence of Ruthenium-Nickel Supported Catalysts

Abstract

The oligomerization of C2-C4 light hydrocarbon gasses in the presence of ruthenium and nickel supported catalysts is investigated. Determined selectivity of the catalysts by isooctane. Catalytic properties of the catalysts depend on the supported metals on the carrier. The nature of carrier also affects on reaction selectivity. The ruthenium-nickel supported bimetallic pillared montmorillonite is showed good selectivity to isooctane and value is about 60.8% at conversion 87.0%.

Propane-Propylene Oligomerization Over Modified Pillared Clay Catalysts

“…The chemical, structural and textural characteristics of the modified clay and catalysts from its derived were widely examined in our previously report. They are belonging to type of pillared clay catalysts, with well ordered pillar and mesopore structure [17]. The main features of the catalysts prepared on this basis are shown in Table 3.…”

Application of Modified Clay Catalysts in Oligomerization of Light Olefins

“…But deactivated upon coke formation, therefore adding noble metals are less sensitive to coke and perform the high activity. In our previous work noble metal-doped Ga and Cr-pillared clays to be an efficient catalyst for the oligomerization of C 2 -C 4 olefins [32,33]. In continuation of our work, the present paper is to study the effect of doped metal cations to the activity and selectivity of the pillared clay catalyst over oligomerization reaction.…”

“…% of impregnated metals were varied from 0.5 to 2.0%. Pillared clay preparation carried out by the method proposed in [32]. Prior to pillaring process, the clay was saturated with sodium ions through exchange with 1M NaCl for 8 h, and then washed with deionized water in order to remove residues of NaCl as determined by the AgNO 3 .…”
