BRIQUETTE BASED ON PRESSED LIGNOCELLULOSE BODY SATURATED WITH LIQUID FUEL Russian patent published in 2014 - IPC C10L5/00 C10L5/14 C10L5/36 C10L5/44 

FIELD: chemistry.

SUBSTANCE: briquette consists of a pressed lignocellulose body, containing: (a) 60-90 wt % cuttings of grass stalks and (b) 10-40 wt % scutched lignocellulose binder with degree of scutching of 38-75°RS (Shopper-Rigler degrees), preferably 45 70°RS, (said percentages being expressed in dry weight relative the dry weight of the sum of (a) and (b)) and from fuel which is liquid at room temperature, having a flash point of 30-150°C, which saturates the pressed lignocellulose body, wherein said briquette has a substantially cylindrical shape and has a central smoke conduit with a star-shaped cross-section. The method of making the briquettes comprises the following steps: (1) mixing an aqueous suspension of lignocellulose binder (b) with cuttings of grass stalks (a) in such proportions that the ratio (per dry weight) of the lignocellulose binder (b) to the cuttings of the grass stalks (a) ranges from 10/90 to 40/60; (2) moulding the mixture obtained in a suitable unit of the mould (encircling part)-anti-mould (encircled part) type at temperature of 40-120°C at pressure of 3-12 bar, applied for 5-120 s; (3) removing the obtained pressed body from the press mould; and (4) saturating the pressed body removed from the press mould with fuel which is liquid at room temperature, having flash point of 30-150°C.

EFFECT: obtaining a solid fuel briquette with low weight and a shape which provides multiple points of ignition, concealed inside the central smoke conduit.
