Higher Alcohol Synthesis: Product Analysis Using the Concept of Effective Carbon Numbers

Abstract

A catalytic setup for Fischer-Tropsch synthesis to alkanes and alcohols is described. Within this single-channel reactor unit the reaction conditions can be varied in the ranges of 25 -400°C, 1 -100 bar, and 300 -120 000 h -1 gas hourly space velocity (GHSV). The broad product spectrum is efficiently analyzed by GC/MS. The concept of effective carbon numbers, as typically applied in refining and high-molecular chemistry, is suitable for the product spectrum comprising mainly alkanes, alkenes, alcohols, aldehydes, and carboxylic acids. This article provides details about the setup and general measurement procedures.

Quantitative Analysis of Aminoalcohols and Polyamines Using Effective Carbon Number

“…Расчет ECN молекулы с использованием количества и типа присутствующих функциональных групп позволяет проводить количественный анализ без предварительной калибровки. Этот подход особенно полезен в случаях, когда анализируемые пробы содержат сложную смесь органических соединений, когда стандарты недоступны, и когда достаточно точности в пределах нескольких процентов [3][4].…”

Carbon Dynamics on the Molybdenum Carbide Surface during Catalytic Propane Dehydrogenation

“…[15] CNT-supported systems have also been investigated in methanol steam reforming [16] or higher alcohol synthesis. [17] The present work concerns the reactivity of Mo 2 C and V-doped Mo 2 C in propane activation including a detailed analysis of the active surface with the aim to improve our knowledge on the relations between phase composition, surface chemistry, and reactivity of molybdenum carbides in catalytic reactions of hydrocarbons. The motivation arises particularly from the question as to whether the reducing gas mixture obtained in typical selective oxidation processes over, for example, Mo/V mixed oxide catalysts beyond full O 2 conver-Abstract: The effect of the gas-phase chemical potential on surface chemistry and reactivity of molybdenum carbide has been investigated in catalytic reactions of propane in oxidizing and reducing reactant mixtures by adding H 2 , O 2 , H 2 O, and CO 2 to a C 3 H 8 /N 2 feed.…”

Higher Alcohol Synthesis Over Rh Catalysts: Conditioning of Rh/N-CNTs by Co and Mn Entrapped in the Support

“…The standard reaction conditions were: p = 100 bar, H 2 /CO = 1, T = 350 °C, flow rate = 10 mL min −1 . The setup and the method of product analysis have been described elsewhere [28].…”
