A process for regenerating a used acidic catalyst which has been deactivated by conjunct polymers by removing the conjunct polymers so as to increase the activity of the catalyst is disclosed. Methods for removing the conjunct polymers include hydrogenation, addition of a basic reagent and alkylation. The methods are applicable to all acidic catalysts and are described with reference to certain ionic liquid catalysts.

An integrally mounted apparatus for washing out vehicle-mounted concrete mixing drums is disclosed. The washout apparatus includes an open-ended elongate, relatively rigid shaped hollow guide tube mounted in fixed relation to the support structure support of an inclined mixing drum and extending in fixed relation to the open end of the drum between the fins and charge hopper. A flexible hollow hose is threaded through the guide tube. The hose has a receiving end connected with a source of cleaning fluid under pressure and a discharge end which protrudes from the end of the guide tube as it ends inside the open end of the mixing drum. A forward hose stop is provided for preventing the hose from slipping back down through the guide tube and a rear hose stop is provided for limiting the travel of the discharge end of the hose outward from the end of the guide tube.
摘要:
The present invention describes novel methods of designing protein kinase modulators, particularly modulators that interact at the interface between two protein kinase domains. In some embodiments, the methods comprise determining the position of at least one site between the first domain and the second domain, wherein the modulator binds to the at least one site and wherein the at least one site is not an ATP binding site.
摘要:
Filter elements are provided for removing a liquid challenge material dispersed in a carrier fluid. The filter element comprises a three dimensional, self-sustaining, fluid transmissive body comprising a plurality of thermoplastic fibers bonded to each other at spaced apart points of contact. The fibers collectively define a tortuous fluid flow path through the fluid transmissive body from a fluid inlet surface to a fluid outlet surface. At least a portion of the thermoplastic fibers comprise a surface-forming material having a surface energy that is less than a surface tension of the challenge material.

An implantable medical device includes a radio-frequency (RF) telemetry circuit connected to an energy source through a power connection module to obtain power when a user initiates an RF telemetry session. After the session is completed, the power connection module shuts off the at least one portion of the RF telemetry circuit. Power-on examples include a wireless telemetry activation signal received by a low power radio receiver in the implantable device, a physical motion detected by an activity sensor therein, an activation of an inductive telemetry circuit therein, a magnetic field detected by a magnetic field detector therein, and/or a telemetry activation signal detected by a sensing circuit included therein. Power-off examples include a wireless termination signal received by the implantable device, a delay timeout after the session, and/or a signal received by an inductive telemetry circuit in the implantable device.
摘要:
A process for oligomerizing a Fischer-Tropsch derived feed containing oxygenates which comprises (a) reducing significantly the oxygenates present in the Fischer-Tropsch derived feed by contacting said feed with a hydrotreating catalyst under hydrotreating conditions in a hydrotreating zone and recovering from the hydrotreating zone a Fischer-Tropsch derived hydrotreated feed which contains a significantly reduced amount of oxygenates as compared to the Fischer-Tropsch derived feed and also a significant amount of paraffins; (b) pyrolyzing the Fischer-Tropsch derived hydrotreated feed in a thermal cracking zone under thermal cracking conditions pre-selected to crack the paraffin molecules to form olefins and collecting an olefin-enriched Fischer-Tropsch feed from the thermal cracking zone; (c) contacting the olefin-enriched Fischer-Tropsch feed with a Lewis acid ionic liquid catalyst in an oligomerization zone under oligomerization reaction conditions; and (d) recovering from the oligomerization zone a Fischer-Tropsch derived product having molecules characterized by a higher average molecular weight and increased branching as compared to the Fischer-Tropsch derived feed.
