A model for transfer processes in column apparatuses has been done. The model may be modified for different apparatuses as columns with (or without) packet bed, two (or three) phase airlift reactors and fluidized bed reactors. The mass transfer is result of different volume reactions as a chemical, photochemical, biochemical or catalytic, reactions, or interphase. mass transfer. The using of the average velocities and concentration permit to solve the scale-up problems. A hierarchical approach for model parameter identification has been proposed.

The paper demonstrates the thermal admittance procedure as a technique to quantify the dynamic thermal properties of two uninsulated rammed earth building components subjected to radiative and conductive heat transfer processes. With the aid of Australian climate data and a climate chamber, this research paper uses a dynamic thermal property calculator developed by Arup in accordance with EN ISO 13786:2007 to quantify the performance of a homogenous rammed earth envelope subjected to in-situ measurements that mimic real conditions.

In Situ Derivatization

A bismuth trifluoromethanesulfonate (triflate)-catalyzed (2.0 mol-%) multicomponent reaction involving the allylation of dioxolanes followed by in situ derivatization with anhydrides to generate highly functionalized esters has been developed under solvent-free conditions. Most reagents used to date for allylation of dioxolanes are highly corrosive and are often required in stoichiometric amounts. In contrast, the use of a relatively non-toxic and non-corrosive bismuth(iii)-based catalyst makes this methodology especially attractive for scale-up.
