Anylysis on Carbon Emission Based on the Life Cycle of New Coal Chemical Industry

Wu Juanni,Zhang Yueling,Tian Yajun and Xie Kechang

Strategic Study of CAE 2015, Volume 17, Issue 9,   Pages 69-74

Abstract:

New Coal Chemical Industry is developing vigorously recently, which not only leads to a significantcarbon emission growth from coal conversion, but also from the upstream and downstream industrial chainIn order to comprehensively figure out the potential influence of New Coal Chemical Industry to climatechange, Life Cycle Assessment method is used to calculate the current and potential CO2 emission of coalto olefins (CTO), direct coal to liquid (CTL), indirect CTL, and coal to synthetic natural gas (SNG)

Benzene alkylation with long chain olefins catalyzed by ionic liquids: a review

QIAO Congzhen, CAI Yonghong, GUO Quanhui

Frontiers of Chemical Science and Engineering 2008, Volume 2, Issue 3,   Pages 346-352 doi: 10.1007/s11705-008-0045-9

Abstract: The introduction of ionic liquids to alkylation process gives a choice for “green production” in the petrochemical and detergent industry. A lot of papers and patents have been published using chloroaluminate ionic liquid as a novel catalyst for alkylation with high reactivity and easy separation from reactants. These included the acidity, characterization, determination and catalysis technologies in batch and continuous operation mode for different scales. According to published data and several results of pilot alkylation,including the authors’ experience,the prospect of chloroaluminate ionic liquids for commercials was also discussed. It has been pointed out that there still are many difficulties and challenges to be overcome for commercial application of the ionic liquid catalyst.

Effect of temperature in the conversion of methanol to olefins (MTO) using an extruded SAPO-34 catalyst

Ignacio Jorge Castellanos-Beltran, Gnouyaro Palla Assima, Jean-Michel Lavoie

Frontiers of Chemical Science and Engineering 2018, Volume 12, Issue 2,   Pages 226-238 doi: 10.1007/s11705-018-1709-8

Abstract: The methanol-to-olefin (MTO) reaction was investigated in a bench-scale, fixed-bed reactor using an extruded catalyst composed of a commercial SAPO-34 (65 weight percentage, wt-%) embedded in an amorphous SiO matrix (35 wt-%). The texture properties, acidity and crystal structure of the pure SAPO-34 and its extruded form (E-SAPO-34) were analyzed and results indicated that the extrusion step did not affect the properties of the catalyst. Subsequently, E-SAPO-34 was tested in a temperature range between 300 and 500 °C, using an aqueous methanol mixture (80 wt-% water content) fed at a weight hour space velocity (WHSV) of 1.21 h . At 300 °C, a low conversion was observed combined with catalyst deactivation, which was ascribed to oligomerization and condensation reactions. The coke analysis showed the presence of diamandoid hydrocarbons, which are known to be inactive molecules in the MTO process. At higher temperatures, a quasi-steady state was reached during a 6 h reaction where the optimal temperature was identified at 450 °C, which incidentally led to the lowest coke deposition combined with the highest H/C ratio. Above 450 °C, surges of ethylene and methane were associated to a combination of H-transfer and protolytic cracking reactions. Finally, the present work underscored the convenience of the extrusion technique for testing catalysts at simulated scale-up conditions.
