Syn-gas-based mono ethylene glycol synthesis in Pujing ChemicalApplied Petrochemical Research - Tập 2 - Trang 23-26 - 2012
Nianjun Luo, Yang Ji, Yanpeng Mao, Bo Zhang
Mono ethylene glycol (MEG) is a kind of important fundamental chemical, mainly used in polyester synthesis. Traditional MEG production is based on petroleum resources. This study reports about a new kind of MEG technology to synthesize CO and hydrogen, developed by Pujing Chemical. Laboratorial researches were performed well by developing both carbonylation catalyst and hydrogenation catalyst. Lat...... hiện toàn bộ
DRIFTS study of Fe promoter effect on Rh/Al2O3 catalyst for C2 oxygenates synthesis from syngasApplied Petrochemical Research - Tập 9 - Trang 211-219 - 2019
Fang Li, Weixing Qian
DRIFTS experiments such as CO adsorption, CO-TPSR and CO+H2 were designated to study the effect of Fe promoter on the key steps of C2 oxygenates formation from syngas. The CO adsorption results demonstrated that Fe weakened CO adsorption and especially the bridging adsorption. It was found in CO-TPSR experiments that the catalyst with lower Fe loading is more easily dissociated while the ones with...... hiện toàn bộ
Removing of hydrocarbon contaminated soil via air flushing enhanced by surfactantApplied Petrochemical Research - Tập 2 - Trang 51-59 - 2012

Surfactants enhanced air sparging actually acts to displace the organic contaminant entrapped in soil pores. In this work, a comparison study was carried out between two air-flushing modes, namely, continuous air flushing and pulsed air flushing, which was conducted to remediate soil contaminated with waste-lubricant oil. Therefore, coarse sand was artificially polluted and mixed well with waste-l...... hiện toàn bộ
The time-on-stream stability of some selected bifunctional nanoporous-based catalysts in n-heptane hydroisomerisationApplied Petrochemical Research - Tập 4 - Trang 189-207 - 2013

In this work, some commercial nanoporous-based catalysts, such as USY, beta and mordenite zeolites loaded with Platinum metal acting as bifunctional catalysts, were used for hydroisomerisation experiments in a fixed-bed reactor at the atmospheric pressure and at feed space time 5.12 h−1 to hydroisomerise n-heptane over a temperature range of 210–270 °C. The study aimed to evaluate the changes with...... hiện toàn bộ
Ultrasonic condition boosts up the rate of phase transfer catalyzed polymerization of acrylonitrile in two-phase systemApplied Petrochemical Research - Tập 7 - Trang 85-96 - 2017
Elumalai Marimuthu, Vajjiravel Murugesan
An ultrasound condition associated with phase-transfer catalyst (PTC) has great diverse applications in synthesis of various organic and polymeric materials because of its fast reaction and high yield in short period of time. Phase transfer catalyst (cetyltrimethylammonium bromide as PTC) extracts the reactive radical anion from aqueous phase and transfer to organic phase whilst ultrasound conditi...... hiện toàn bộ
Hydrogenation of levulinic acid with and without external hydrogen over Ni/SBA-15 catalystApplied Petrochemical Research - Tập 8 - Trang 153-162 - 2018
Mohan Varkolu, Hari Babu Bathula, Young-Woong Suh, David Raju Burri, Seetha Rama Rao Kamaraju
A series of Ni/SBA-15 catalysts were prepared by impregnation method for the hydrogenation of levulinic acid (LA) to γ-valerolactone in a fixed bed reactor at atmospheric pressure. The catalysts were characterized by XRD, TPR, AAS, Pulse chemisorption, SEM-EDAX, TEM, BET Surface area and XPS. The catalyst 30 wt% Ni/SBA-15 exhibited excellent catalytic performance (97% yield) at 250 °C due to the p...... hiện toàn bộ
Environmental impacts of ethylene production from diverse feedstocks and energy sourcesApplied Petrochemical Research - Tập 4 - Trang 167-179 - 2013
Madhav Ghanta, Darryl Fahey, Bala Subramaniam
Quantitative cradle-to-gate environmental impacts for ethylene production from naphtha (petroleum crude), ethane (natural gas) and ethanol (corn-based) are predicted using GaBi® software. A comparison reveals that the majority of the predicted environmental impacts for these feedstocks fall within the same order of magnitude. Soil and water pollution associated with corn-based ethylene are however...... hiện toàn bộ
Ethanol photoreactions over Au–Pd/TiO2Applied Petrochemical Research - Tập 4 - Trang 55-62 - 2014
A. K. Wahab, S. Bashir, Y. Al-Salik, H. Idriss
A prototype Au–Pd/TiO2 catalyst was prepared, characterized and tested for the photoreaction of ethanol. XPS Au4f and Pd3d indicated that the as-prepared material is composed of metallic Au, metallic Pd as well oxidized Pd (Pd2+). Ar ion sputtering (5 min) of the catalyst surface resulted in almost total reduction of Pd2+ to metallic Pd in addition to considerable reduction of surface Ti cations ...... hiện toàn bộ
