Various embodiments of the present invention are directed towards a system and method relating to depositing vapor in a sample. For example, a device includes a vapor source chamber configured to contain a vapor source material to generate vapor. An activation chamber is configured to contain a sample. The activation chamber is in fluid communication with the vapor source chamber to receive the vapor. A permeable separator divides the vapor source chamber and the activation chamber, and isolates the sample in the activation chamber while allowing vapor to pass between the vapor source chamber and the activation chamber. The device is sealable and configured to apply vacuum to the vapor and sample, to cause deposition of the vapor into the pumice stone samples.

A continuous flow process (CFP) for the production of an acid chloride includes the following steps: (i) providing or forming a first reactant comprising a chlorine-donating compound; (ii) providing or forming a second reactant comprising a carboxylic acid; (iii) providing a first continuous flow of the first reactant into a reactor at a first flow rate; (iv) providing a second continuous flow of the second reactant into the reactor at a second flow rate; and (v) mixing the first reactant and the second reactant in a portion of the reactor and reacting the first reactant and the second reactant to provide a reaction product comprising an acid chloride.

A device for converting cellulose to sugar has a reaction chamber with a plurality of control components, and a control assembly. The control assembly is operatively connected to the reaction chamber, a drive assembly and control components to transmit and receive interoperability signals. The device has an inlet hopper with a detector, a crusher, an outlet hopper, a sensor assembly, a steam inlet, and a carbon dioxide inlet. The inlet hopper is configured to receive and analyze proportion data of matters in a feedstock and catalyst mixture via the detector. The crusher receives and grinds the mixture from the inlet hopper to induce chemical reaction for producing sugar. The outlet hopper is configured to determine a proportion data of matter in the grinded mixture. The control assembly is configured to determine adjustments need to be performed on the components and drive assembly to optimize the sugar production.

Processes for producing olefins include passing a hydrocarbon feed to a hydrocarbon cracking unit that cracks the hydrocarbon feed to produce a cracker effluent, passing the cracker effluent to a cracker effluent separation system that separates the cracker effluent to produce at least a cracking C4 effluent including 1-butene, 1,3-butadiene, and isobutene, passing the cracking C4 effluent to an SHIU that contacts the cracking C4 effluent with hydrogen in the presence of a selective hydrogenation catalyst to produce a hydrogenation effluent having a 2-butenes concentration greater than or equal to the sum of the concentrations of 1-butene and isobutene. The processes include passing the hydrogenation effluent to a metathesis unit that contacts the hydrogenation effluent with a metathesis catalyst and a cracking catalyst downstream of the metathesis catalyst to produce a metathesis reaction effluent comprising at least propene.
