Experimental and theoretical studies on oxy-cracking of Quinolin-65 as a model molecule for residual feedstocks

Abstract

Oxy-cracking is a combination of oxidation and cracking reactions for converting heavy hydrocarbons into commodity products with minimal emission of CO2.

Surface modification of carbon nanotubes with copper oxide nanoparticles for heat transfer enhancement of nanofluids

“…5b). 65,66 This latter peak and the one at 933.83 conrm that the CuO is higher in 10 wt% CuO sample compared with 1 wt% CuO which is also evidenced in Fig. 6a and b for the highest contribution of O 1s at 531.4 eV in 10 wt% CuO-CNT.…”

A combined experimental and density functional theory study of metformin oxy-cracking for pharmaceutical wastewater treatment

“…As mentioned in our previous work, 13,47 the oxy-cracking reaction is initiated by free-radical species, such as cO, cHO 2 , or cOH, primary attacks on the organic molecule. This leads to a free-radical chain reaction to form further radicals.…”

Oxy-Cracking Reaction for Enhanced Settling and Dewaterability of Oil Sands Tailings

“…Upon oxy-cracking, most of the organics are converted to carboxylic acids and alcohols. 20 This is expected as oxy-cracking is a simpler version of the intense processes used for oil extraction, but at mild temperatures and pressures it also produces carboxylic acids. These acids can be easily adsorbed from the water using various processes to reduce their toxic effect as described in our previous studies.…”

“…Oxycracking experiments were conducted at conditions previously found to be optimal for this reaction but for a different application, at a temperature of 473 K over a 2 h duration. 20,26 Figure 6 shows the images of the compact mudline after the oxy-cracking reaction took place. The images compare the mudline for the oxy-cracked sample with the original tailings water at different settling times.…”
