Syn-gas-based mono ethylene glycol synthesis in Pujing Chemical
Applied 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
Simulation and optimization of different pressure thermally coupled distillation for separating a close-boiling mixture of n-butanol and iso-butanol
Applied Petrochemical Research - Tập 7 - Trang 143-150 - 2017
Lixin Liu, Liuliu Zhu, Lanyi Sun, Minyan Zhu, Guili Liu
Substantial quantities of energy are required in conventional distillation columns applied in high-purity separation of close-boiling mixtures. To achieve energy saving of distillation, a novel different pressure thermally coupled distillation (DPTCD) was proposed for separating the close-boiling mixture of n-butanol and iso-butanol. Both this intensified energy integration technique and two other... hiện toàn bộ
Enterprise-wide optimization in a petrochemical plant: a MILP approach to energy efficiency improvement
Applied Petrochemical Research - Tập 7 - Trang 151-160 - 2017
Delano Mendes de Santana, Sérgio Ricardo Lourenço, Douglas Alves Cassiano
Public policy, dollar rate, market prices, contracts values and equipment efficiency influence the costs of the energy sources at an ethylene plant. The aim of this research is to identify energy efficiency opportunities at the energy management resources in a petrochemical industry. It was proved that using MILP makes it possible to achieve energy efficiency gains. MILP proved to be effective, ac... hiện toàn bộ

Advances in the study of coke formation over zeolite catalysts in the methanol-to-hydrocarbon process
Applied Petrochemical Research - Tập 6 - Trang 209-215 - 2016
B. Liu, D. Slocombe, M. AlKinany, H. AlMegren, J. Wang, J. Arden, A. Vai, S. Gonzalez-Cortes, T. Xiao, V. Kuznetsov, P. P. Edwards
Methanol-to-hydrocarbon (MTH) process over acidic zeolite catalysts has been widely utilised to yield many types of hydrocarbons, some of which are eventually converted into the highly dehydrogenated (graphitized) carbonaceous species (cokes). The coking process can be divided into two parallel pathways based on the accepted hydrocarbon pool theory. From extensive investigations, it is reasonable ... hiện toàn bộ
DRIFTS study of Fe promoter effect on Rh/Al2O3 catalyst for C2 oxygenates synthesis from syngas
Applied 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 surfactant
Applied Petrochemical Research - Tập 2 - Trang 51-59 - 2012
Th. Abdel-Moghny, Ramadan S. A. Mohamed, E. El-Sayed, Shoukry Mohammed Aly, Moustafa Gamal Snousy
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 hydroisomerisation
Applied Petrochemical Research - Tập 4 - Trang 189-207 - 2013
Faisal M. Alotaibi, Raed H. Abudawood, Hamid A. Al-Megren, Mohammed C. Al-Kinany, Arthur A. Garforth
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 system
Applied 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 catalyst
Applied 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
