Abstract:
A solid shaped composite adsorbent for reducing deactivated catalyst residues and contaminants from a post polyolefin solution polymerization mixture is disclosed. The composite adsorbent comprises 70 - 90 wt% of an alumina component; 30 - 10 wt% of a clay component; and 0.5 - 3.5 wt% of at least one alkali metal component selected from the group consisting of elements in Group 1 A of the modern periodic table.
Abstract:
The present disclosure relates to a fiber suitable for packaging. The fiber comprises a photocatalyst and optionally, a silicon containing linker. The photocatalyst is bonded to the fiber by means of a first functional group pre-present on the fiber and optionally, a second functional group generated by a silicon containing linker. The chemical bonding between the fiber and the photocatalyst imparts durability and wash ability to the fiber. A packaging material prepared using the fiber of the present disclosure can be used for the storage of plant produce.
Abstract:
The present disclosure relates to a process for the preparation of a fertilizer product which includes preparing a first mixture, pugging, kneading the mixture to obtain dough and processing the dough to obtain shaped articles which are dried to obtain the fertilizer product of the present disclosure. The fertilizer product of the present disclosure includes elemental sulfur, at least one swelling agent, at least one binding agent, at least one plant growth regulator, optionally at least one inorganic material and water.
Abstract:
The present disclosure provides a process for the removal of impurities from impure heavy alkylated benzene (HAB) using an adsorbent. The adsorbent can then be regenerated by using a non-carcinogenic and eco-friendly fluid medium, which can be recovered and reused. The process of the present disclosure avoids the use of steam for regeneration/displacement of impurities from the adsorbent and hence, minimizes effluent generation having higher COD.
Abstract:
The present disclosure provides a process for removing metal contaminants from a contaminated fluid stream comprising the step of contacting said fluid stream with macroporous alpha alumina to obtain a fluid stream containing less than 50 ppm of metal. The fluid stream can be selected from the group consisting of a stream of mineral acid(s) and a stream of alkylene(s); and the metal contaminant can be at least one of elemental metals and metal oxides. The process further comprises a step of obtaining spent macroporous alpha alumina and regenerating active macroporous alpha alumina therefrom by washing said spent macroporous alpha alumina with at least one purified stream selected from the group consisting of a stream of mineral acid(s) and a stream of alkylene(s).
