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
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
MCM-41-supported vanadium catalysts structurally modified with Al or Zr for thiophene hydrodesulfurizationApplied Petrochemical Research - Tập 9 - Trang 47-55 - 2019
Yelisbeth Escalante, Franklin J. Méndez, Yraida Díaz, Marcel Inojosa, Myloa Morgado, Miguel Delgado, Ernesto Bastardo-González, Joaquín L. Brito
Vanadium catalysts supported on Al(Zr)-MCM-41-type materials were prepared by impregnation. Textural and structural properties, elemental composition and electronic structure were determined by N2 physisorption, small-angle XRD, SEM–EDX and UV–vis DRS, respectively. Al-containing materials showed mostly of Al framework and a small fraction of Al extra-framework species. Zr-containing materials pre...... hiện toàn bộ
Comparative study of the dry reforming of methane on fluidised aerogel and xerogel Ni/Al2O3 catalystsApplied Petrochemical Research - Tập 3 - Trang 91-99 - 2013
Zheng Jiang, Xin Liao, Yongxiang Zhao
The xerogel and aerogel Ni(20 wt %)/Al2O3 catalysts were prepared through incipient-wetness-impregnation and co-precipitation-supercritical drying (CP-SCD), respectively. All the fresh and used catalysts were well characterised using FESEM, BET, XRD, H2-TPR and H2-TPD techniques. Their properties and catalytic performance in dry reforming of CH4 in a fluidised bed reactor were comparatively invest...... hiện toàn bộ
Isothermal study of asphaltene adsorption over 4A, 13X, ZSM-5, clinoptilolite zeolites, and phoslockApplied Petrochemical Research - Tập 10 Số 1 - Trang 49-54 - 2020
Maryam Baninaam, Seyed Abolfazl Hosseini, Ahmad Reza Abbasian
AbstractThe paper reports the adsorption studies of asphaltenes of Iran’s heavy crude oil on some natural and synthetic alumino-silicates. Asphaltenes were precipitated using n-heptane. Toluene was used as a precipitating solvent of asphaltenes and several zeolites including 4A, ZSM-5, Clinoptilolite, and La-modified bentonite (Phoslock) ...... hiện toàn bộ
